💎 Why Gistr is different
Gistr captures information where you work and turns it into organized threads—so timestamps, screenshots, highlights, and AI outputs stay connected to their sources and remain searchable over time.
On YouTube, you can take timestamped notes, grab video screenshots, and highlight the transcript—making visual and spoken content equally easy to revisit.
On web articles, highlight key passages and generate concise AI summaries, then keep everything together with the source in one thread in your Gistr workspace.
The result is a durable record of what you captured and why it matters, ready to extend and connect across future sessions.

- Stelios Angelis
- Extremely useful extension! I was frustrated because these days almost no YouTube title offers useful information, but mostly works as click bait. So, I must spend at least some time browsing through the video watching parts of it, just to understand if I may be interested in the content or not. Gistr helps me quickly "Get the Gist of it" and decide if I get any value watching the video or reading the full transcript or not. Gistr lets me quickly discard the garbage and spend more time on YouTube videos that make a difference to me and are actually worth it!
