Video to notes

Turn any YouTube video into notes

Paste a YouTube link into Sochen and ask for notes: it watches the whole video, frames and sound, and answers with timestamps you can tap to jump to that moment. It works for lectures, tutorials, recipes, podcasts and your own recordings.

How it works

  1. 1

    Paste the link

    Or tap the video button in the chat to upload a file, up to 500 MB.
  2. 2

    Ask for what you need

    “Study notes with timestamps”, “every ingredient with its amount”, “the exact steps he follows”.
  3. 3

    Jump, ask, make a file

    Tap a timestamp to watch that moment. Ask follow-ups, or have Sochen turn it into a document or a checklist.

What people ask it

  • A lecture or class

    Notes by topic with timestamps, the formulas on the board, and a quiz to test yourself.

  • A recipe video

    Every ingredient with its amount, the steps in order, and a shopping list.

  • A how-to or repair video

    The exact steps and the tools needed, with the moment each one is shown.

  • A screen recording of a bug

    What happened, step by step, so someone can reproduce it.

  • A meeting or interview recording

    A summary, the decisions, and who's doing what.

  • A long video, one part

    Ask about 40:00 to 55:00 only, and pay only for that part.

Questions

Is it free?+
A 10-minute video costs about 9 credits. Every account starts with a 7-day trial of Plus for one payment of $5 (₹199 in India). It never renews: after 7 days you pick a plan if you want to keep going. The free tools at sochen.dev/tools need no account at all.
Which videos can Sochen watch?+
Public and unlisted YouTube videos, links to video files, and videos you upload (up to 500 MB). It can't open private, members-only or logged-in videos, like Instagram reels or paid courses: download or record them and upload the file instead.
How long can a video be?+
Up to 3 hours. For anything over 20 minutes, Sochen tells you what it will cost and asks first. You can also ask about just one part, like 12:00 to 20:00.
Does it hear what's said, or only see the screen?+
Both. It watches the frames and listens to the sound, so it catches what's said, what's written on screen and what's shown.
Can it turn a video into a document?+
Yes. Ask for notes as a Word document or PDF, a checklist, a spreadsheet of what's shown, or a quiz, and Sochen makes the file in the chat.
What happens to a video I upload?+
It's kept privately in your account for 7 days, then deleted. To watch it, Sochen sends it to Google's Gemini model.
