FasTube

Jump to the exact moment in any video with AI-generated timestamps

AI-generated video 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.

One-click side panel

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.

Works beyond YouTube

Handles videos on other platforms as well as articles and PDFs, so the same timestamp workflow applies almost anywhere you read or watch.

ChatGPT visual integration

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.

Strengths & Pros

+Removes the slowest part of video research by jumping directly to relevant timestamps
+Very small install footprint with fast advertised response times
+Works across general websites, PDFs and ChatGPT responses rather than only one platform
+Clear privacy stance: the developer declares no collection or sale of user data
