Grounded Brain remembers what matters to you across notebooks, and you stay in control of it.
Private by design
Sign in with Google. Your notebooks, sources and memories are visible only to you.
How it works
Up and running in three steps
Create a notebook
One notebook per topic keeps every answer focused.
Add your sources
Upload, paste or link them. We read and index each one.
Ask, then study
Chat with citations, then generate material to revise.
Questions, answered
Frequently asked questions
What is Grounded Brain?
Grounded Brain is an AI notebook that answers questions only from the sources you add, such as PDFs, websites, YouTube videos and GitHub repositories. Every answer includes citations that point to the exact passage, so you can verify it.
How is Grounded Brain different from a general AI chatbot?
A general chatbot answers from what it learned in training. Grounded Brain retrieves passages from your own sources and cites them, so answers are traceable and stay focused on your material.
What kinds of sources can I add?
You can add PDFs up to 10 MB, websites, YouTube video transcripts, GitHub repositories, pasted text and Markdown. Each source is read and indexed before it is used in chat.
Can it create study material?
Yes. Grounded Brain can turn your sources or a conversation into summaries, key takeaways, flashcards, quizzes, mind maps, reports and repo wikis.
Is my data private?
Yes. You sign in with Google, and your notebooks, sources and memories are visible only to you. You can edit or delete anything, including what the assistant remembers.
Who built Grounded Brain?
Grounded Brain was built by Mohammed Saif, a senior software engineer focused on full-stack development and generative AI. You can find more about him and his other work at his portfolio, https://www.imohdsaif.in/.
How do I get started?
Sign in with Google, create a notebook, add a source and ask your first question. It takes under a minute.

The story
Grounded Brain is my hands-on project for exploring full-stack AI: how retrieval-augmented generation (RAG) pipelines work end to end, and what it takes to turn a language model into something people can trust.
I'm building it step by step, from ingesting and indexing sources to retrieving the right passages and answering with citations you can verify. Every stage teaches me something new about shipping generative AI features properly.
It's actively evolving. Try it out, and tell me what you'd like to see next.
