Jump to the exact moment in any video with AI-generated timestamps
Highlight a question or keyword and FasTube returns the moments inside a video where that topic is covered, so you can skip straight to the answer.
Launches from the toolbar or with the Ctrl/Cmd + M keyboard shortcut, appearing as a Chrome side panel that never covers the content you are watching.
Handles videos on other platforms as well as articles and PDFs, so the same timestamp workflow applies almost anywhere you read or watch.
Connect chatbot replies to the underlying source material so an answer written by ChatGPT can be located and verified visually in the original video or page.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
