💎 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.

▶️ YouTube features
• Timestamped notes linked to the exact moment you’re viewing.
• One-click video screenshots to capture diagrams, slides, and visual details.

• Notes and highlights organized as a thread for each source.

🤝 Works the way you do
