The Windows and Mac apps do all of it on your own device, so your lectures never leave your computer, and your transcript is always yours to copy or export.

Elasticity of Demand
How sensitive consumer demand is to a change in price or income.
Everything you need. All built in.
Live concept detection
Demist listens to your microphone and flags unfamiliar concepts as your lecturer speaks. Each definition shows on screen, matched to your subject and year.
Automatic glossary
Demist saves every concept with its definition. Your glossary fills itself while you focus on the lecture.
Spaced repetition flashcards
Demist queues each concept as a flashcard and uses SM-2 spaced repetition to schedule reviews at the right time.
Session summaries
When you stop recording, Demist generates a summary of your lecture. Find it in your history alongside the term list and transcript.
Full session history
Every lecture you record or import is stored with its terms, transcript, and summary. Rename sessions, browse past notes, and come back to anything.
File import
Upload a recording, slide deck, or transcript. Demist pulls every unfamiliar concept and builds your glossary in seconds.
Notion sync
Export your glossary or summaries to Notion in one tap, or import your own lecture notes to extract terms automatically.
Quiz mode
Test yourself on your glossary with multiple-choice or recall questions. A results screen shows what you got wrong so you can retry just those terms.
How it works
Record, import, or paste a link. Demist handles the rest.
Record live or import from anywhere
Tap record before a lecture, or upload a recording or slide deck. In the browser there is nothing to set up or install, and the Windows app is a single install from the Microsoft Store.
Unfamiliar terms are explained as they appear
During live recording, definitions pop up on screen the moment your lecturer says something you might not know. For imports, Demist scans the full content.
Your glossary and flashcards build themselves
Every concept is saved with its definition and a summary of the session. Flashcards queue with spaced repetition on a schedule built around when you'll forget.
Windows app
Now on the Microsoft Store. Transcribed on your own machine.
The desktop app runs speech recognition locally, on your computer's own processor. Your lecture audio is never uploaded, not to us and not to anyone else. Install it once and record straight from your laptop.
Mac app · Beta
Now in beta for Apple Silicon. Same transcription, on your own computer.
The same locally-run transcription, term detection, and translation as the Windows app, now on M1 and newer Macs. It's early: the build isn't notarized yet, so macOS shows a security warning the first time you open it. The install guide below walks through it - it takes one extra step, not a workaround.
