The open-source chatbot making RAG seamless.

Heelix is a desktop chat app written in Rust and Tauri, automatically augmenting LLM queries using text data from your machine collected via accessibility API and OCR.

• The app collects text from documents visible in the foreground
• Collected content organized into local SQL and vector databases
• Top K results automatically injected into LLM query as context
• Full privacy, only local data storage, use your own API key with Claude or OpenAI

Why we built Heelix

• We wanted to build an app that makes it lighting fast to reference everything you've read on any app when interacting with LLMs - no high spec requirements or massive battery consumptions, no API integration, just install and the it works. All while maintaining privacy and full user control.

Requirements

• Install Node 18 (recommended: https://github.com/nvm-sh/nvm, normal install: https://nodejs.org/en/download/package-manager)
• Install rust https://www.rust-lang.org/tools/install
• Install tesseract (optional) https://tesseract-ocr.github.io/tessdoc/Installation.html

How to run
