AI that watches your video and writes study notes as you watch
Captures code, equations, diagrams and slide content exactly as they appear, so notes are complete even on videos with no captions.
Generates headings, bullets and syntax-highlighted code blocks that drop straight into an Obsidian vault or any Markdown editor.
One click adds the current frame to your notes at the right timestamp, ideal for diagrams, demos and UI walkthroughs.
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.
AI YouTube summaries and key insights without leaving the video page
The extension reads the video and returns a condensed version of its content in seconds, so you can decide whether the full video is worth your time.
Rather than dumping a wall of text, Quicksense surfaces the central arguments and takeaways, which is useful when you are revising or researching.
Summaries appear inside YouTube itself, so there is no copying links into a separate dashboard or tab to get a result.
The developer reports an average summary turnaround of roughly five to ten seconds depending on video length, keeping note-taking within the flow of watching.
