Show HN: Brainstorm.gg – Get ideas out of your head fast

[ajoshu]

How to get ideas for your next startup or side project. - Use this tool

A more focused way of generating ideas would be to have a multi-step approach, define the scope, collect information, generate ideas, clean up, expand/deduplicate, evaluate and rank, see a figure 4 from a review [1]

I tried to do it based on ICLR conference, and rank via LLM-tournament, see result https://openreview-copilot.eamag.me/projects and process https://eamag.me/2025/Paper-To-Project

You’ve described my manual consulting process :)

Except when I have access to the right ears I force some measurable success metrics at the beginning to maintain scope stability after agreements.

Interesting, thanks

Given the title, thought this was going to be another "write it down, get it out of your head" note-taking tool. Boy was I surprised when the first thing I typed in exploded into 10 more things to think about!

[ajoshu]

Thanks for trying it out!

Love this! UX nit: I love that I can 'lock' good ideas in and ask for a fresh batch, but I want a way to say 'I reject this idea and don't want to see it again.'

I kept getting the same 'wrong flavor' ideas even after 2-3 rounds.

[ajoshu]

Interesting, I could prob store that locally then make it avoid re-generating

Thanks for feedback

Whenever I click "Brainstorm", I get an error saying "Failed to fetch ideas." Just wanted to report it in case it's helpful for the developer.

[ajoshu]

Thanks for the feedback I'll look into those logs now! Sometimes specific questions can throw errors, which I am trying to improve.

[ajoshu]

This really exploded in traffic, thanks to everyone who tried it out and gave me feedback!

Evidence that ideas are a dime a dozen.

I'm told: > Enter a topic and get some ideas

And when I enter something I get: "Error: Invalid topic"

[ajoshu]

Hi, yes this happens very rarely, it's usually triggered when it thinks you are trying to escape out of the subject, try to limit your question length a little. - Thanks for giving it a try.

It was fun, I’ll try it again when I have more time.
