A surface you actually want to think on.
Rich text. Sketches. Attachments. Comments. AI that turns videos, lectures, and your own messy drafts into transcripts, summaries, and quizzes. Less switching. More thinking.
Rich documents
Headings, lists, tables, code, callouts. Markdown export. Print-to-PDF with page breaks that actually break right.
Sketch & handwriting
Notability-style canvas with Apple Pencil pressure, lined / dotted / grid paper, multi-page layout, three eraser modes, lasso selection, and shape recognition.
YouTube → notes (Pro)
Paste a YouTube link. Get a transcript, a structured summary, and a quiz — appended right to the note. The kind of "study hack" your favorite influencer keeps promising.
Smart Notes recording (Pro)
Hit record on a lecture, meeting, or call. Live transcript. Rolling summary. A clean insert when you stop.
One-tap quizzes (Pro)
Generate a personalized quiz from any note — multiple choice, fill-in-the-blank, short answer.
Attachments & comments
Files inline, comments per note for shared Spaces, and links to the calendar event the note belongs to.
PDF annotation, in-line
Open a PDF inside a note, highlight, draw, and write on the pages — same Apple Pencil feel as the canvas. Three eraser modes, lasso selection, and shape recognition all work on the PDF too. No exporting, no app-switching. The PDF lives with the note so your reading and your thinking stay together.
Save Copilot answers as notes
When a Copilot reply is worth keeping, one tap turns it into a real note — same hub, same workspace, fully editable. Highlight a passage and turn it into events or tasks without leaving the chat.
Hub-scoped notebooks
Open the Academic workspace and the notes list shrinks to your courses. Operations shows just your project notebooks. Same notes; calmer view.
What it looks like in your week
"Smart Notes captures the room, the transcript goes into my course note, and a quiz drops in by the end of class."
"Paper surface, sketch when I need it, typed when I don't. It's the first note app I open by choice."
"Comments per note in a Space mean we don't need a separate chat app for doc feedback."
The ones people ask first
- Each note lives in a notebook (a folder) or a Team. Notes have rich text, sketches, attachments, comments, and AI tools (YouTube import, Smart Notes recording, one-tap quizzes — all Pro). Personal notes are private until you 1-to-1 share them. Team notes are visible to everyone in the Team. Notes can be linked to a calendar event so they pop up when the event runs.
- Paste a YouTube link into a note (or use the YouTube button on the editor toolbar). Kairo fetches a clean transcript, generates a 7-point summary with timestamps, and creates a multi-choice quiz from the content. Everything is inserted into the note, and the quiz is saved alongside so you can retake it. Pro feature — beta testers and admins get it for free.
- Hit the Smart Notes button in any note and press record. Kairo captures the room (lecture, meeting, call) through your microphone, transcribes live using your browser's speech recognition, and updates a rolling summary every 8 seconds. When you stop, the transcript + summary are inserted into the note. Audio is processed locally where the browser supports it; nothing is uploaded for training. Pro feature.
- Click the Quiz button on any note. Kairo extracts key concepts and definitions and generates a 6-question quiz with multiple choice, fill-in-the-blank, and short-answer questions. Take it, see your score with explanations on missed questions, retry as many times as you want. Quizzes are saved to your library. Pro feature.
