Show HN: Allein - Markdown editor with AI autocompletion, completely offline

[szdoro]

Hi everyone! I built Allein, a Markdown editor powered by Ollama — use your own LLMs locally for AI-assisted writing, completely private, no account required, and works offline.

What it does:

- Context-aware autocompletion (think GitHub Copilot for Markdown)

- Writing improvements (spelling, grammar, readability)

- Flexible model selection—swap between different LLMs based on your needs and your device's capabilities

- Full-featured Markdown editor with live preview

Why I built it: I wanted GitHub Copilot-like autocompletion in a lightweight text editor—something between Apple Notes' basic suggestions and a full IDE. As a non-native English speaker, I also wanted built-in writing improvement tools to help me improve my English.

Tech: Built with Tauri, React, Rust, and Ollama for local LLM inference. Ollama is incredibly powerful, and this felt like a perfect use-case for it.

I'd love to hear your thoughts. Feedback on the concept and any features you'd like to see are very welcome!

Love the simplicity. It would be great some type of zone discraction function where users can't do anything else just taking notes in a fullscreen app.

That’s an interesting use case. Some popular writing tools offer “Zen” or “Focus” modes, so it can definitely be valuable. Thanks for the suggestion

This looks really good, love the local LLM support. Will try this instead of Notion which is my current note taking app. Thank you!
