Turn saved web pages and documents into an AI knowledge base you can question

This is our editors' assessment out of 5, not an average of user ratings. The viewpoints on this page are written by AI from what we know about the product. They are not customer reviews.

Finally a bookmark tool that actually answers questions about what I save.
UI feels a bit like an abandoned student project.
Great for quick research document chats.
Sync between extension and web app glitches out occasionally.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
The browser extension saves the article or page you are reading straight into your myGPTBrain knowledge base without copying and pasting.
Ask questions in natural language and get context-rich answers grounded in the pages and documents you have saved.
Generate a summary of any saved document and pull out the key points so you can skim before committing to a full read.
Chat with several documents at once, which makes it practical to compare sources or synthesize information across a set of files.
Set custom instructions to shape responses, and upload images, ZIP files, Office files and other formats as inputs.
myGPTBrain approaches the "read it later" problem from the consumption side rather than the collection side. Instead of building a bigger bookmark pile, it gives you a place to save pages as you browse and then immediately interrogate that content: ask a question, get a context-rich answer drawn from the material you saved, and pull out the parts that actually matter.
Beyond bookmarking, it acts as a lightweight document assistant. You can give it custom instructions so the answers follow your own style or format, upload a range of file types including images, ZIP archives and Office documents, and chat with several documents at once — useful when you want to compare sources or pull a synthesis across reports. Summarization and key-highlight extraction are built in for each saved item.
The extension itself is deliberately tiny and does one job: save the current page to your myGPTBrain dashboard in one click. The heavy work happens in the web app, which is where your uploaded documents, saved pages and conversations live. It is a sensible fit if you already save a lot of reading and want AI to help you actually use it rather than just store it.
Save research pages as you find them and later ask questions against your own collected material instead of re-searching the web.
Upload several reports or papers, chat with them together, and get summaries and highlights to prioritize what deserves a careful read.
Use multi-document chat to check where several files agree or diverge without manual cross-referencing.
Set custom instructions so extracted highlights come back in the tone or structure you need for your own writing.
