Why did you built Heelix?

We wanted to reimagine note-taking and document organization for the era of AI and make it lighting fast - so you can easily organize your knowledge and tap into AI with the right context rather than hoping that RAG works.

What system specs are required to run Heelix?

Our app is designed to work across all Mac and Windows machines with no specific hardware specifications threshold.

Is Heelix free?

The desktop version of the app is completely free - just plug in your API key and you're good to go!

Do I need to download a new app version periodically?

Right now, yes, but we'll add auto-updater in the next iteration of the app.

What language models does Heelix currently support?

You can pick the model in the model picker, right now available options include Sonnet 4.0, OpenAI's o-1, gpt-4o and o4-mini, and Gemini. Just sent us a message and we'll add other ones in the next version.
