Sightnote

Turn a YouTube lecture into notes

Paste the link to a public YouTube lecture and Sightnote writes study notes from what the teacher says and what is on the board or slides. Every note links to the moment in the video it came from, so you can check it.

Made up to show the format. Not from a real lecture.

Rotational Motion · Lecture 12

3. Torque and angular acceleration

Torque is the turning effect of a force. Just as force causes linear acceleration, torque causes angular acceleration.

Formula · from the board

τ = r F sin θ = I α

Teacher stressed this: anticlockwise torque is taken as positive.

  • Torque is largest when the force is at 90° to the arm.

How it works

  1. Paste the link

    Any public YouTube lecture. Private and unlisted videos can't be read, so upload the recording instead.

  2. We read the board and the audio

    The frames and the speech are read together, so formulas are copied as written. You can watch each stage while it runs.

  3. Study from the notes

    Chapter notes with timestamps, flashcards and a one-page quick revision sheet. Download a PDF, share a link or send it to Notion.

Questions

Which YouTube videos work?

Public videos. Private and unlisted videos can't be read. If you have the file, you can upload it instead (up to 1 GB).

What happens with a long lecture?

Each video is processed up to its first 30 minutes. If a video is longer, you see a notice before you confirm.

Does it need the video's captions?

No. Sightnote reads the video's frames and audio together, so it picks up what is written on the board as well as what is said.

Can the notes include things that weren't in the lecture?

No. Notes contain only what is in the video. Every block links to its timestamp, and a block that can't be linked to the video is left out.

What if someone has already made notes for this video?

If the lecture is already in our library, its notes open straight away and use none of your hours.

How much does it cost?

You start with free hours, once, after you verify your phone. Paid plans give you new hours every week. The plans are listed above.
