Timestamped pins

Press N on any video page. The video pauses, you type your thought, press Enter — video resumes exactly where it left off.

Works everywhere

Activates on popular video sites by default. Enable on any other site in one click from the popup — no settings page needed.

Jump back instantly

Click any timestamp in your notes and the video seeks to that exact moment and resumes playing.

AI summary

After 7+ pins, summarise your notes into key points with AI. Summary is saved with your session. 10 free summaries per month — no API key needed.

Export to Markdown

Download your pins and AI summary as a clean Markdown file. Paste into Notion, Obsidian, or any note app you already use.

Private by default

All notes stay on your device in local browser storage. Nothing is synced to any server. No account required.

Dark mode

Follows your system preference automatically. Switch between light, dark, and auto in Settings.

Site control

Enable or disable Grovepin on any site directly from the popup. Built-in support for YouTube, Vimeo, Coursera, Udemy, Loom, and more.
