A second brain that actually thinks
Notebook is a personal knowledge tool that turns scattered notes, tasks, and voice memos into a connected graph of ideas — extracted, linked, and recalled by AI.
Everything is built around the loop of capture, enrich, recall — so the system gets smarter the more you use it.
Quick-add tasks with natural language. Drop in notes, links, or voice memos from anywhere — sorting can wait.
Every note is parsed for people, places, projects, and concepts so your knowledge auto-organizes as you write.
Notes link to entities, entities link to notes. Browse the web of connections you've built without filing anything.
Ask questions in plain English. Vector search surfaces the right notes by meaning, not just keywords.
Record a thought, get a transcript and a structured summary in seconds. Background-played narration for everything you've saved.
Inbox, Today, and Upcoming views with project tagging, priorities, and a sane keyboard-first workflow.
Designed for the way ideas actually arrive — fragmented, mid-meeting, at 2am — not the way filing systems wish they did.
Hit Q for quick-add, paste a link, or record a voice memo. No tags, no folders, no decisions.
Notebook extracts entities, generates a summary, classifies the type, and pins it to your knowledge graph.
Convert notes into tasks. Schedule them. Today and Upcoming views keep your focus sharp.
Search semantically, browse by entity, or follow links between ideas. Your past thinking compounds.
Every primary action has a shortcut. The command bar (⌘K) is the fastest way to jump between projects, search notes, or trigger any AI workflow.
