HoverNotes

AI that watches your video and writes study notes as you watch

Visual AI that watches the screen

Captures code, equations, diagrams and slide content exactly as they appear, so notes are complete even on videos with no captions.

Structured Markdown notes

Generates headings, bullets and syntax-highlighted code blocks that drop straight into an Obsidian vault or any Markdown editor.

Timestamped screenshots

One click adds the current frame to your notes at the right timestamp, ideal for diagrams, demos and UI walkthroughs.

Live Translate and Hovie assistant

Listen to a speaker in your own language while the video stays in sync, and ask Hovie to explain or summarise any moment using your notes and screenshots.
