I have been struggling a lot with focus during research recently, and AI apps and browser windows dont help with that, I go on tangents in conversations with AI, so I built an app that would refuse to answer questions if out of context.

So it's basically a PDF reader + Rich text notes + AI chat (RAG optimized for learning with context of the document) + annotations that can link these chats and notes to PDF content.

It's free to try, give it a go if you have a similar workflow. If you have a PDF heavy workflow, you'd find it useful.

Its very lightweight as there are only the required features (5Mb dmg , 12Mb unpacked)
