AI Video Note Taker — Transcribe Any Video Locally
Transcribe any video — live or recorded — with CFAI's local AI. No video upload required. Works on Zoom recordings, YouTube, Loom, courses, and more.
How to Extract Notes from Any Video Without Uploading It
You have a backlog of recorded video meetings, online course lectures, YouTube tutorials, and Loom walkthroughs that you know contain useful information — but re-watching them is time-consuming. AI video transcription solves this, but most tools require you to upload the video file to a cloud server, raising privacy concerns for confidential meeting recordings.
CFAI captures audio from your Windows PC's system audio — which includes any video playing on your screen. Whether you're watching a recorded Zoom call, a Loom video, a YouTube lecture, or a course video, CFAI transcribes the audio locally using Whisper as the video plays. No file upload required. The resulting transcript lets you search, summarize, and query the video content in minutes.
For live video calls (Zoom, Teams, Google Meet), CFAI transcribes in real time during the meeting itself. For recorded videos, you play the video at normal speed while CFAI processes the audio locally. Either way, your video content stays on your device.

Frequently Asked Questions
Can AI take notes from a video automatically?
Yes. CFAI captures system audio from any video playing on your Windows PC and transcribes it locally using Whisper. It works for Zoom recordings, Loom videos, YouTube, online courses, and any local video file — without uploading the video.
How do I transcribe a recorded Zoom meeting?
In CFAI, enable system audio capture. Play the Zoom recording on your PC. CFAI transcribes the audio in real time as the video plays. For a 1-hour recording, it takes approximately 1 hour to transcribe at normal playback speed (or faster if you increase playback speed).
Can I get a transcript from YouTube videos?
YouTube has its own auto-generated captions, but they're not always accurate and can't be queried with AI. CFAI captures YouTube audio from your system audio and generates a higher-accuracy local transcript you can then query with Document RAG.
What is the best AI for extracting notes from video?
For offline/local video note-taking: CFAI is the best option — no upload, local Whisper processing, Cognitive Map, Document RAG. For cloud-based video analysis: Descript and Loom AI work well for videos already in those platforms.
Does CFAI work with Loom videos?
Yes. Play any Loom video in your browser on Windows. CFAI captures the audio from your system audio stream and transcribes it locally — faster and more private than uploading the Loom to a third-party transcription service.
