Open a notebook
One topic, one library. Sources never leak into another notebook — a course, a paper, and a side project stay apart.
Grounded research desk

Pour in PDFs, YouTube, Gmail, Calendar, or Drive. Ask in text or voice. Every claim should open a page or a clip. Delete a source, a chat, or a notebook — and its vectors and memory leave with it.

Add what you are studying
PDFs, websites, YouTube, captions, notes — plus Gmail, Google Calendar, and Drive when you connect Google. Wait until the card says Ready — that is when it can be asked.
Ask in text or voice
Type, or hold the mic. Answers stream with citations. Only two or three sources show under the reply; the rest still inform the writing.
Check the passage
Tap a citation. A PDF jumps to the page. A video starts at the timestamp and plays. A note highlights the excerpt.
Study in Studio
Turn the same corpus into a two-host podcast, a YouTube roadmap, flashcards, a FAQ, or a briefing — without leaving the desk.
Pin what should last
Follow-ups remember the thread. Pin a fact so the next question does not forget what you already established.
Sources

PDFs
Opens on the cited page.
Websites
Paste a public URL.
YouTube
Plays from the timestamp.
Captions
VTT or SRT transcripts.
Notes
Paste text any time.
Paste, .eml, or import from Gmail.
Calendar
.ics or import Google Calendar.
Drive
Browse a folder, tick the files.
MCP tools
GitHub, Jira, Postgres, JSON.
From the rest of your desk
Gmail,Calendar,Drive—pouredin,notpastedforever.
One Google connection. Three doors. What you pick becomes a source in this notebook — and leaves when you delete it.
01
The thread you meant to study
Gmail
Connect once. Pick messages — they become sources in this notebook, not a second inbox. Marketing chrome is stripped so the model reads the letter, not the footer.
02
Meetings have a paper trail
Calendar
Import Google Calendar or drop an .ics. Events land as a readable source you can ask against — who, when, and what was on the docket.
03
Only the files you tick
Google Drive
Walk a folder. Check Docs, Sheets, Slides, PDFs, or text. ChaiBook indexes what you choose — nothing else in the drive walks in uninvited.
Leave no crumbs
Deletethecup,thetealeavesgowithit.
Memory is notebook-scoped on purpose. When you throw something away, ChaiBook does not keep a quiet copy of the embeddings underneath.
The leaf leaves the cup
Delete a source
Indexed vectors for that file go first. Memory, episodes, and graph nodes tagged to it follow. Remove the last source and Studio artifacts leave with the empty cupboard.
The steam forgets the kettle
Clear a chat
The thread, chat-derived memory, episode embeddings, the knowledge graph, and Studio artifacts — podcast, FAQ, flashcards, briefing, roadmap — vanish. Sources and facts you pinned stay on the desk.
The cupboard is empty
Delete a notebook
The whole library goes: sources, chat, Studio artifacts, chunks, memory, graph, and the notebook’s Mem0 records. Nothing from this desk lingers for the next one.

Stays out
One notebook, one subject
Keep a course, a paper, or a project isolated so answers do not mix unrelated files.
Use cases
Builtforstudying,notbrowsing.
Students
Exam prep
Drop lecture PDFs and a playlist. Ask for definitions, generate flashcards, then play the podcast on a commute.
- Cited answers for last-minute checks
- Flashcards from the same notes
- Roadmap through course videos
Researchers
Reading a paper
Load the PDF and related pages. Ask where a claim is stated, jump to the page, pin the result for the next meeting.
- Page-accurate citations
- Pin findings into memory
Self-learners
A YouTube course
Paste a playlist. ChaiBook indexes public videos, then a roadmap walks concepts in order — click a node and the clip plays.
- Timestamped citations
- Autoplay from the cited moment
Teams
A briefing, not a guess
Paste notes, pull Gmail threads, calendar, Drive files, and links. Ask for a synthesis, export the chat, or generate a briefing you can send — every claim still has a source.
- Gmail, Calendar, and Drive import
- Notebook-scoped answers

Cited chat
Answers come from your sources. Tap a citation to see the passage.
Ask by voice
Dictate a question. The mic fills the composer in Chrome, Edge, or Safari.
Spoken summary
The speaker rewrites the answer for listening — short, natural, no citation numbers.
Source viewer
Open the PDF page, webpage, or video clip the answer used. YouTube starts playing.
Podcast
Aarav and Meera host an audio overview generated only from this notebook.
Learning roadmap
A path through your YouTube sources, pinned to the moment each idea appears.
Flashcards & briefing
Study cards, a FAQ, and a briefing — all from this notebook only.
Memory
Pin facts and keep the thread. Follow-ups remember what you already established.
Gmail, Calendar, Drive
Connect Google once. Import mail, events, or files you pick — they stay inside this notebook.
External tools
Connect GitHub, Jira, Postgres, or paste Claude / VS Code MCP JSON. Chat can call them live.
Wipe on delete
Remove a source, chat, or notebook and its vectors, memory, graph, and Studio artifacts leave with it.
On a phone, switch between Sources, Chat, and Studio. On a large screen they sit side by side.
FAQ
Straightanswersbeforeyoupouranotebook.
A notebook-scoped research desk. You add sources, ask questions, and every answer is supposed to point back to a page, a clip, or a note — not the open web.
It is instructed to stay inside your sources and to refuse when they do not cover the question. Always open a citation if the claim matters. The model can still be wrong; the viewer is there so you can check.
PDFs, public websites, YouTube videos or playlists, VTT/SRT transcripts, pasted notes, email (paste, .eml, or import from Gmail), calendar (.ics or Google Calendar), Google Drive files you choose from a folder, and MCP tools (GitHub, Jira, Postgres, or pasted JSON). Indexing runs in the background. Chat unlocks when at least one source is Ready, or when a tool is connected.
Yes. Connect Google from the add-source dialog — one authorization covers Gmail, Calendar, and Drive. Pick messages, events, or files; they become ordinary sources in that notebook. Paste and .eml / .ics still work without connecting.
Delete a source and its indexed vectors plus tagged memory leave. Remove every source (or the last one) and Studio artifacts go too — podcast, FAQ, flashcards, briefing, roadmap. Clear chat and the thread, episode vectors, chat memory, knowledge graph, and those Studio artifacts leave — pinned facts and sources stay. Delete a notebook and the whole cupboard goes: files, chat, chunks, memory, Studio, and Mem0 records scoped to it.
The reply is written from a wider set of passages. The chips under chat show the strongest two or three unique sources so the desk stays readable. Inline [n] still opens the exact excerpt.
The mic transcribes into the composer. The speaker on an answer first writes a spoken summary with the model, then plays it — OpenAI speech when a key is configured, otherwise the browser voice.
Yes. Each notebook is its own library, and it belongs to your account. After you sign in with Google or email, you only see your notebooks. Vectors, chat, and memory do not mix across notebooks or across users. Delete a source, chat, or notebook and those embeddings leave with it.
Yes, to create or open a notebook. Create an account with email and password, or continue with Google. If you tap New notebook while signed out, the sign-in screen opens first. You can only delete your own notebooks and chats.
After you have sources, generate a podcast, a YouTube learning roadmap, flashcards, a FAQ, or a briefing. Those cards also sit in the chat column.
Yes. Switch between Sources, Chat, and Studio. On a large screen they sit side by side.
