Launch HN: Muddy (YC S19) – Multiplayer browser for getting work done

[lele0108]

Hey HN! This is Jimmy, Ron and Austa from Muddy (https://feelmuddy.com/). Muddy is a browser for work that automatically keeps project files organized in the same place where you use and share them. Here’s a demo: https://www.youtube.com/watch?v=tZr49aN3sjQ. Download and try it out here: https://feelmuddy.com/.

Building together in the past, we were incredibly frustrated with how much friction there is to get anything done on our computers. I was losing time everyday digging through chat logs looking for that one important link or breaking others out of flow by asking where something is.

Web apps promised to help us get more done—and they do, but each in its own silo, so there’s still a ton of redundancy to deal with. Every app has its own way of organizing files, its own notification inbox, its own search system. Conversations live everywhere and there isn’t a single view to see everything about a project. Remember when files simply lived in folders rather than the “cloud”?

We started dedicating time to organizing our files in shared docs and limiting new apps we used. This helped – but the second we didn’t stay on top of organization, links became stale and things got messy again.

Muddy started as a hack week project we built for ourselves—a single place to use web apps with others, but personalized for each user automatically. Everyone gets their own view for every project, designed around how they work.

Muddy users work on projects in spaces, which are like automatic tab groups. Users share apps (any site works—a Github PR, Figma file, Trello board—whatever you want) into the project’s shared timeline and Muddy automatically opens relevant tabs for you. It’s a single click to open up all the apps you need for the project.

Under the hood, Muddy works in the background to keep track of the timeline and uses a LLM to continuously organize apps and keep everything on to date. It considers signals like the popularity of a file, naming conventions, and conversations to figure out what’s relevant. So everyone is presented with an updated list of important tabs, without anyone lifting a finger. Our actual browser is based on Chromium.

When you need to revisit something from weeks ago, you can rewind the project timeline to that point in a single click. Apps open up in the timeline so you’ll see your files right away. For sites that don’t have built in collaboration features (like documentation), Muddy lets you do annotations directly on the website.

Projects sometimes get big and need to be broken up. Across all your spaces, Muddy can answer questions like ChatGPT, cite your files as sources, and return apps directly. This is possible since Muddy’s AI shares your browser and can use your authenticated apps locally (with privacy in mind).

Other browsers like Chrome and Arc focus on solo productivity with sharing as a bolt-on. We think productivity depends on how well you can work with others, and should be the first class consideration. And doing organizational work manually is unsustainable.

Muddy will have paid subscriptions for teams with additional features like shared passwords, team organization, custom shortcuts, and SSO management. Those aren’t built out yet and the base product will be free. No part of our revenue will come from data monetization.

We’d love for you to give Muddy a spin! You can download Muddy for Mac or Windows on our website and add others once inside: https://feelmuddy.com/. We’ll be around to answer questions and look forward to any and all feedback!

[TIPSIO]

The feature for sending messaging and posting comments to a tab is some pretty clever and creative UX. Seriously next level future stuff and congrats for just coming up with the concept.

I like that it's all timeline based. For my use case, we currently use Front email thread and then link to a Shared Dropbox where we post everything (including links to like a Google Doc or webpage). I think having chronological bookmarks like you do would be clearly better. I also know many people who use Google Groups and Google Doc to document progress too -- which I think would be insane / nightmare but teams do it. You all definitely would solve that automatically.

Couple other notes:

- Whenever I screenshare with a team or others I see 1000 bookmarks or tabs on their browser. I could not imagine the nightmare of how that would impact my workflow or the timeline. Trusting AI to clean stuff up or hunt is not for me.

- I can tell you all have been heads down blitzing (dog in video, phone ringing in background of another) but I think a separate "Solutions" page where you tackle specific examples would be nice to see or browse.

- Maybe too much or not really your goal, but right now need some sort of client integration for an outside person. I can't imagine giving access to a client on a whim and training them on this. Instead, maybe automatic email integration where their emails show up in the timeline and can respond directly from there. Would produce a really great timeline for where things left off and when things are being communicated. Being able to sub-comment and share files/updates/things on Front on email threads is one of the most killer features for productivity and a team. Mixing this with what you all have could be even more next level. Again though, might not be the goal.

Congrats and best of luck! Big fan of people trying to tackle PM stuff and think you all are doing a great job.

[lele0108]

Great idea for creating some specific videos for engineers, designers, etc.

Browsers are interesting since they can do almost anything but "you can do anything you want!" is intimidating for many new users.

We've given e-mail thought and it's certainly a door we are considering as we keep on building. Has anyone built a browser without thinking about an email client? :P

[webappguy]

Integrating an AI tab organizer of which they’re very few and the chrome one is essentially garbage, would make this a definite purchase for me. The AI should organize my own tabs and the ones I share

[idoh]

What's the story around getting into YC in 2019 and then launching in '24? I'm guessing there were some interesting pivots along the way ...

[lele0108]

You are right. We came in letting hosts open experience stores in Airbnbs (try on an Oculus at a hosts home). Difficult to attribute our sales so we moved on.

COVID hit and we had the itch to look at the browser in a different light. Building a browser seemed intimidating...but it was quarantine. Long story short, built a few different ideas and here we are :)

[aranibatta]

You can actually check out all the material from the pivots inside the app. There's a walkthrough in the Getting Started space when you first set up.

[kisonecat]

Totally evokes the good memories I have of "Google Wave" as a way for folks to collaborate on rich documents. Super cool.

[aranibatta]

Google Wave for the web has been one of the more popular ways to describe Muddy. I didn't see it at first, but I'll take it :)

[gaudystead]

Google Wave was the first thing that came to mind for me as well. RIP

That being said, this looks like a nice spiritual successor to it!

[jasonlotito]

Yep! Glad to see I wasn't the only one who remembered Wave and what it had the potential for.

[oaktowner]

I came here to say this -- couldn't agree more. Very positive feelings and this nails it (and adds some stuff, too).

[sachinkesiraju]

This is super impressive. Love the demo, especially the AI recall feature that deeplinks your files and @'s collaborators. This product feels like the obvious evolution of the digital workplace after the cloud. Is the plan to eventually integrate more native collaboration tools (Kanban boards, team password sharing, cloud file storage) after chat?

[aranibatta]

I think we might have more base interfaces (notes, sheets) but we want to encourage people to keep building first class software. All in one is worst of all

[zuhayeer]

Congrats on the launch! Awesome to see this release as an early user who was able to check it out. The shared workspaces and shared browser windows with context in place has been incredible for collaborating with folks. We have our Figma design, Notion doc, and Gitlab MR all in the same space so we don't have to go searching for each one independently or have them cross-linked to each other.

[seism]

Love to see a hack week project get this far. The timeline and signals features look awesome, and I can't wait to give this a try. Hope you also have thoughts (and a business model) for more private, ephemeral spaces - enabling short term collaboration, e.g. for freelance/remote/hack work.

[aranibatta]

Curious what you had in mind?

[ekhar01]

This is so cool. Much respect. I am curious what tech stack you are writing this with? Is it electron or maybe lower level?

It might also be cool if it could automatically import sheets or google docs if I were to drag a csv or .txt file in and just magically open the project up. I hate having to upload via google drive

[lele0108]

Electron isn't meant for building a browser and has perf / other limitations. We went with a full Chromium backing with some patches to allow us to write our UI in web tech.

Looking to explore such automations in the near future -- important to us that it feels great to create new files in Muddy (and have Muddy do any of the busywork we are used to)

[joloooo]

This is awesome. What are your thoughts on Office365 tools and Muddy? We don't use Google docs and would love to have a similar experience. That said, I could probably manage certain teams to move away from our MSFT reliance with this flow.

Really excited to try this out and follow along.

[aranibatta]

I think if EVERY tool you use at work is in the Office suite, teams is just better. If you have any other tools like one off SaaS or devTools, Muddy could be a fit.

[antidnan]

This is really cool! Congrats on the launch!

I think my usage of figma,sheets,etc. is 90% single player, until the moment of sharing my (maybe unfinished) work, where I go through an intense period of collaboration with others for an initial review, then tails off, and becomes async.

I can't see myself using muddy for the single player part, but it sounds interesting for after that initial intense collab process. Especially if the process includes multiple apps, as opposed to a single design review in figma etc. I find the longer running async collab is when I get the most scatterbrained across apps.

[lele0108]

I felt this pain a lot. Never really resonated with all-in-one apps so we always had a few places to check for every project. Figuring out the right links was hard and prone to distraction.

In a way, we like trying new software. Downside is each app has the need to build their own slightly different file system, which makes finding things extra challenging. Wanted to solve with Muddy.

[t1c]

So, despite being based on Chromium, there's no Linux builds? Would like to try this but me and my entire team uses Linux.

[lele0108]

Hear you! Coming soon. There are some OS specific patches we made to Chromium that make this less straightforward

[aranibatta]

We have Ubuntu and Fedora users through Wine. Not ideal I know, but enough to try out unless you have a super custom Arch setup

[toddmorey]

Question: What were the technical requirements that necessitated a custom browser? That would really sink adoption for my team. Any plans to have a lite version that can work inside your favorite browser (even if plugin is required)?

Idea: your privacy section only talks about cookies and ads, but all my privacy questions were around the AI features that would use all our team's messages and work across apps as context. Would definitely cover that piece.

[aranibatta]

Most of the stuff we do that people seem to really like can't be technically or physically done inside of another browser's tab unfortunately. Chrome extensions are too limiting as well. We started off as a chrome extension inside of our previous company, and hit a wall pretty quickly.

For the LLM calls, the one's you currently see are patching calls to a variety of model providers. As long as they hold their end of the TOS you should be fine. Everything else is happening locally.

We will launch a self-host option for Muddy. Cool features like hosting the servers and build process yourself, custom icon and skin on the app, and other internal rules you can set up. Let me know if that's of interest.

[nikunjk]

Congrats on the launch - seems like a neat product. A few questions: 1) It seems like you iterated on a bunch of ideas that landed in this - what were some interesting features that the team was really interested in that you ended up killing? 2) What were the most non-intuitive hard technical challenges? 3) Have you successfully ended up having someone give up on Slack to use this?

[lele0108]

1. Spatial canvas based browser (we called it Sail). Had people who loved it but their team refused to learn it. Spatial tools are just incredibly niche and difficult to get started (besides Google Maps).

2. Auto updating across Mac and Windows (in 2024!!). Google Omaha is hard to setup, Sparkle is jank on Windows. Throw in binary delta support and it's an oof.

3. Our team builds Muddy on Muddy and ditched Slack when product got stable. Few other beta users and their companies as well. Slack is super sticky and has some terrific workflows, but more "quality" conversations today happen natively in apps and almost all apps have commenting functionality. Just easier to talk next to the context. So a lot of Slack convo's become "where is X" and we think Muddy will stop the need for those questions all-together.

[aranibatta]

check the timestamp: https://x.com/SlackHQ/status/367835012315357184

[kingzulu]

The unsubscribe link in your welcome email is not a link, it is just text.

[UmWhatever]

So does "local data stay local" or what? I mean, obviously Trello cards are stored in Atlassian's cloud somewhere and Slack convos are somewhere in Salesforce's series of tubes. I guess what I mean is, if "Muddy works in the background to keep track of the timeline and uses a LLM to continuously organize apps and keep everything on to date", does this mean Muddy ships off local data to some remote API to get it's work done? Or if I'm only ever working within my local network, is the data I'm working with inside the Muddy context as safe as my local network can make it?

[alexkern]

Congrats on the launch! One of the positive byproducts of the open web platform is that products like this are possible. Much of what I share in other communication tools are links to things on the web, but sharing ends up forcing a context switch cost on both my end and the receiving end. Love that Muddy is exploring this problem space since I haven’t felt like other neue-browsers have gone far enough in making browsing itself a more collaborative and in-context experience.

[v3ss0n]

Browsers especially work browsers are very sensitive piece of software which needs to fully respect data privacy and security so it is opensource or burst. If it's not opensource user might just as well, consider it a spyware.

Opensource or Burst.

[watermelon0]

Not disagreeing with your statement, but would add that the majority of businesses use Safari, Microsoft Edge, or Google Chrome, and all of them are closed source.

[pkiv]

Congrats on the launch!! Collaborative browsing is something I've been looking for a few use cases of mine. Excited to try it out.

[yohannparis]

An integration with current chat system (Slack, Teams, etc.) would be neat. Changing where the work happens is a big ask in my opinion.

[TIPSIO]

I can't really imagine how integration with them would work.

I don't want to speak for the Muddy people, but I wager they probably think chat app is kind of miserable experience. This instead tries to have a superior offering of something cleaner, easier to visualize where things are, and then move that "slack/teams" type convo to specific comments and tasks.

[indie_rok]

Nice landing! Just curious how did you do those canvas animations (videos of features of the product)? They look amazing

[TheBengaluruGuy]

i think it's lottie - https://lottiefiles.com/

[sahaskatta]

Congrats on the launch. I recently was trying out Microsoft Edge's built-in Workspaces feature which allows multiplayer collaboration. What would you say are the key differences?

https://www.youtube.com/watch?v=w5AX_HvtYfI

[lele0108]

The main difference is that Muddy automatically creates and updates those shared tabs for you based on what's being added to the project timeline (multiplayer feed of apps/websites).

We used some similar tools like Workona in the past but without constant maintenance, links would get stale and we'd abandon it. Wanted something that did that for us automatically.

(Also we support: website annotations, team presence, and letting you rewind a project's timeline back to any point in time)

[ggsp]

Really cool demo! Curious to try it.

The homepage says "(y)our business model is around selling collaboration services and enterprise features, not ads"—can you expand on this a bit, specifically what you mean by "collaboration services" and how you intend to monetize Muddy?

[csmeyer]

Curious to give this a try, how would you compare it to Arc? I used Arc for a while but eventually just ditched it for going back to chrome

(Also, landing page nit, but the kerning on the H1 is pretty wide, and the kerning in the wordmark is a bit tight IMO.)

[csmeyer]

OK, I tried it out. First thing I did was type a website into the big bar at the top and got an upsell modal for an AI thing... I get the need to make money but this was not a good first experience for me

[jerrygenser]

I spent a little time googling around but even wayback machine is only showing results in 2024 for the domain.

Was there a different project that was being worked on previously? Or is this the only product being launched since YC S19?

[aranibatta]

Previous projects of ours include: sail.online nototo.app

This is the first one with real traction and retention, so it's the first time we started to share on HN. Wanted to make sure it was GA and not a waitlist before we came here

[hasante]

This solves a problem - but i also feel like it could be a chrome or desktop plugin. But then am also wrong because there is a use case requiring intensive sharing where this looks like it solves it deeply. Good job.

[dvaun]

This is super neat. I would love to use this in a team setting if I could convince the org to pay for it.

I saw in another comment that it’s a patched version of Chromium. Are you using CDP for underlying communication?

[jbaczuk]

I'm not sure this would be useful to me, because I don't switch between various projects that would benefit from different tab groups, but sounds like it could be useful! Good luck.

[NayamAmarshe]

Looks very interesting. The chat feature almost looks like a good slack alternative.

I can imagine this being useful to organization where your chats and your work are in the same window.

[aranibatta]

That's the general idea. We found that if you break down the average team's project slack channels, it's a bunch of urls and threads about them. Just wanted to make that experience simple!

[verdverm]

You can use Slack & Discord from browser tabs. That's how I roll

One Chrome window for

- work (slack, jenkins, bitbucket)

- personal (discord, gmail, twitter, HN)

- open source (github, docs, projects)

Each one is a mental box and are kept separate

[whimsicalism]

I can see why managers would love this, social pressure around doing work and working faster.

[aranibatta]

I can't say we haven't heard that. Surprisingly, it's usually more of a TL or most Senior Eng who seems to like those presence features. A lot less cat herding across apps for them.

We have less traction with PMs. Most of the feedback from them implies they like being bombarded with Slack notifications even if they say they don't.

[aboodman]

Please stop doing this:

https://i.imgur.com/2WeVGxK.png

It's so frustrating. Early in your product lifecycle it should be painfully easy to get started and you shouldn't be worrying about this kind of security.

[lele0108]

Good point, we'll fix this in the next update.

p.s. fan of the work on replicache and of course chrome

[lIl-IIIl]

Please keep doing this.

[promiseofbeans]

I don't see any issue with this? It makes sense to keep the accounts secure, and very few people will be coming up with passwords by hand; they'll be using the auto-generated ones from their browser (or from their 3rd-party password manager for the more HN-y types).

[aboodman]

I almost gave up after trying this like three times but as an ex browser developer really wanted to see what ya'll were up to. I think it's an interesting concept. But I bet you will lose tons of trials here.

In fact it should just be google auth (not sure if I missed the option to do that).

[causal]

Cool idea! Curious how it handles auth. Like how do you collaborate on a shared URL without shared credentials

[mschrage]

Love this and am tremendously impressed by this team's persistence. Congrats on the launch!

[psuedo_uuh]

I already have too many tabs open, can you imagine how many would be open on a shared browser?

[pbhjpbhj]

Edge has shared browser "workspaces", I use them solo to have different browsers for different roles. Like a workspace for project A, another for intranet, another for project B, ... the main thing about it is all your tabs are where you leave them and it's a bit more visually manageable than TST which I use at home. Basically means you can have lots of tabs open, but now in different windows (with different colours!).

That feature is supposed to be about 'multiplayer' and has been so good it actually makes me want to see Muddy just because of how positive that 'multiplayer' has been. Weird, huh.

Aside, I'm still mourning Opera Unite.

[andrewfromx]

i can't click the create account button because my screen resolution is small: https://i.imgur.com/EATViKH.png

[rrr_oh_man]

The demo video is excellent!

[astiela]

How do you plan to monitize this and even compete with larger platforms

[decide1000]

Is there a Linux version?

[aranibatta]

Not yet, in the pipeline. Depending on your distro (Ubuntu and Fedora) have users through Wine.

[c01nd01r]

Is creating an account necessary to use the browser? No, thank you.

[bozhark]

This should say “data” not just ads

“All your cookies and passwords are stored locally and never on our server. Our business model is around selling collaboration services and enterprise features, not ads”

[aranibatta]

You're correct. Don't really need to do anything with your data as well. I will change.

[kingzulu]

The unsubscribe link in your welcome email is broken. It isn't a link.

[aranibatta]

Ty for the catch, correcting now. Seems to be for the invite and update emails?

[keshav55]

This is amazing

[otteromkram]

Relevant: https://imgs.xkcd.com/comics/standards.png

[aranibatta]

This post is a right of passage

[hammyhavoc]

wot? no Linux?

[sonicanatidae]

Is there a listing of what data is sent back to your servers and how that data is stored/handled?

I work in a secure environment. I like the idea of this app, but leakage is a huge factor for my teams.

That aside, I've already downloaded a copy and plan to try it out in a non-secure environment. The concepts here look like a great idea. GL and thanks!

[aranibatta]

Nothing sophisticated right now unfortunately. But we're planning on releasing a version where all servers, models, and build CI for the app are self-managed. Let me know if that's of interest.
