Your lectures, turned into notes.

Syft Notes' Home page: Monday, October 12, the day's classes and meetings under Up next, the newest notes with a line about each, a Record button and an Ask bar, and the classes, clubs and what's coming up down the side.

Record

Every word, written down live.

Click Record on Home, in the menu bar or the tray, or press ⌥⇧R (Ctrl+Alt+R on Windows). Syft Notes writes the lecture down as it's said, on your own computer. The audio never leaves it.

  • Type your own notes while it records; the write-up is built round them
  • Pause or stop from the menu bar
  • Or have it written down after class, to save battery
A Machine Learning lecture being recorded: the recording bar with its time, the sound level, Pause and Stop, and the student's own notes typed under Notes as it records.

Notes

Written for you after class.

When you stop, the lecture is filed under its class and written up: a summary, key points, definitions and questions to review, by the AI you choose.

  • Filed under the right class, worked out from what was said
  • Fix or add to the notes yourself whenever you like
  • Plain Markdown files on your computer, one folder per class
The notes for 'The cardiac cycle and cardiac output': a summary, then the key points, with cardiac output and mean arterial pressure written as formulas.

Formulas

Every formula, worked through.

Maths is written the way it was on the board, in proper notation, with each step of a worked example in the order it was done.

Formulas in the notes: a dose worked out as desired over have times quantity, and mean arterial pressure worked through line by line to 93.3 mmHg.

Graphs

Drag a slider, watch it change.

When a lecture is about a curve, the notes draw it from its formula. Move a slider, or press play, and see what each number does.

A graph in the notes: the sigmoid with its tangent at zero and a reading pinned on the curve, Explain this, Quiz me and Where was this said?, and a slider for its steepness.

Diagrams

Click a step to follow it.

A process becomes a diagram you can click through, and anatomy becomes a labelled drawing, made from what your lecturer said.

  • Click a box to follow its arrows
  • Ask about any part: Explain this, Quiz me, or Where was this said?
A labelled drawing of the heart cut open in the notes: the aorta, the superior vena cava, both atria and ventricles, the valves and the pulmonary veins.
A diagram of the five phases of the cardiac cycle as a loop of boxes joined by arrows.

Due dates

Pulled in from Canvas for you.

Syft Notes reads Canvas through your browser with your own sign-in, so there's no password or token to hand over, and it only reads. Nothing on Canvas changes.

  • Everything due across your classes, as a calendar
  • Each assignment's instructions and rubric, your submissions and feedback
  • Works in Chrome and the browsers built on it, such as Edge and Brave
  • And in Firefox 140 or later and the browsers built on it, such as Zen, with the add-on from Mozilla's site
The Due page: October as a calendar, with each class's assignments, quizzes and projects on the days they're due, in the class's colour, and what's missing.

Ask

Answers from your own lectures.

Ask about one lecture, a class, or all of them. The answer comes from your own notes, with the lecture and the minute it was said.

  • An Ask bar on Home, on every class and under every lecture's notes
  • The quick panel from anywhere: ⌥Space on a Mac, Alt+Shift+Space on Windows
  • Answers appear as they're written
An answer to 'What's a normal MAP?': 70 to 100 mmHg, with its formula, from Claude, with the minutes of the lecture it came from, above the Ask bar.

Connect

Works with Claude and ChatGPT.

Turn it on in Settings, and the Claude and ChatGPT apps on your computer can read your lectures and notes to answer your questions. They can't change or delete anything.

  • One Connect button for each app, nothing to type or paste
  • You choose what they can read: lectures, notes, Canvas
Settings, AI apps: Claude Desktop connected, ChatGPT almost done with a Reopen ChatGPT button, Claude Code with a Connect button, and a question to try in Claude.

One computer, or two.

Start on one computer. Later, record on a laptop too with Settings → Your library → Add a laptop, or move your library to a computer at home in Settings → Connection, with nothing to reinstall.

Just this computer

Your laptop records, keeps the library and writes the notes itself. Nothing else to set up; notes are written while it's on.

your laptop records your library notes · Canvas

A laptop and a library

A computer that stays on at home (a Mac mini, an old laptop, any Mac or PC) keeps the library, writes the notes and syncs Canvas, even while your laptop sleeps. Your laptop reaches it at home or, anywhere, over Tailscale.

Your recordings never leave your computers.

  • Your audio never leaves.It's transcribed on the computer that recorded it.
  • No account, no server.There's no Syft Notes cloud. Your library is a folder on a computer you own, and your notes are Markdown files you can open, back up or sync however you like.
  • No tracking.The app doesn't track you or report on what you do. Once a day it sends one anonymous count (a random code for this copy, the app's version, and Mac or Windows) so we know how many people use it. You can turn it off in Settings. Nobody at Syft Notes can see your lectures.
  • You choose the AI.Ollama keeps everything on your computer. Claude Code, Codex or Gemini use the plan you already have, and only when you pick them.
  • Canvas and calendars are read-only.Syft Notes reads with your own sign-in and changes nothing. What it reads goes only to your library.
  • Open source.Every line is on GitHub, so you don't have to take our word for any of this.

The details are in the privacy policy.

Your library in your pocket.

Read your notes, ask a question and see what's due from your iPhone, iPad or Android phone. There's no app store involved: it's a web app your own library serves.

Get the phone app

Free, for Mac and Windows.

The same app for every computer. Setup asks how you'll use it: just this computer, your library, or your laptop. It comes in light and dark and twenty colour themes, and keeps itself up to date, never while it's recording.

Mac

This computer

Needs macOS 15 or later. Open the DMG and drag Syft Notes onto Applications (or just open it: it offers to move itself there). It's signed and notarized by Apple, so it opens like any app from the internet. Allow the microphone when it asks.

Download Syft-Notes.dmg

Windows

This computer

Open the Setup.exe. It installs for your account only, with no questions and no admin rights, then opens Syft Notes by itself. If Windows says "Windows protected your PC", click More info, then Run anyway.
