Your thinking, amplified by AI.
NoteBook is the workspace where students, researchers, and professionals capture ideas, collaborate live, and get instant AI answers — all in one place.
Built for how you actually think.
Six core capabilities that turn scattered thoughts into structured, searchable, shareable knowledge.
Smart Notebooks
Auto-organize your notes with AI tagging, nested folders, and semantic search that finds what you mean — not just what you type.

Ask questions across all your notes. Get summaries, surface connections, and draft new content — trained on your own knowledge base.
Real-time Sync
Every keystroke syncs across all your devices and collaborators in under 200ms. Work together without stepping on each other.
Lightning Fast
Opens in 0.4 seconds. Search returns in 80ms. Built on a custom CRDT engine — no lag, no spinners.
Secure Storage
End-to-end encrypted by default. Your notes are yours — zero-knowledge architecture means even we can't read them.
Smart Alerts
NoteBook watches your deadlines, meeting notes, and action items. It surfaces what needs your attention before you forget — not after.
From idea to insight in three steps.
No steep learning curve. NoteBook fits into your workflow from day one.
Create your workspace
Sign up in seconds and set up your personal or team workspace. Import existing notes from Notion, Obsidian, or plain text — we handle the migration.
Capture & organize
Write freely with rich text, code blocks, math equations, and embeds. NoteBook auto-tags and links related notes as you type.
Ask, learn, and share
Query your entire knowledge base with natural language. Generate summaries, flashcards, and quizzes — then share with one click.
