Research Companion

A desktop library for your papers. Import PDFs, read and annotate, and link each note back to the passage it came from. Ask questions across your library and get answers that cite the source.

You choose the model, local or hosted. Claude comes first. ChatGPT, anything on OpenRouter, or any OpenAI-compatible API also work.

Open research gets the best Claude model you can access. Secure research stays on your machine.
