Turn plain text into diagrams, infographics, and presentation-ready visuals.
Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.

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.
