A few useful details.
Do I need an account?
You can capture, draft, and review without an account. Sign in with Google or X when you choose to publish.
What can I annotate?
Select text on a regular webpage, or mark a moment from a video or podcast. Some sites and Chrome-managed pages restrict capture. The extension explains what is available on the current page.
Can I use this on my phone?
You can read and share published annotations on your phone. Capturing a new annotation requires the desktop Chrome extension.
What stays with the annotation?
Your selected excerpt or recorded clip, your commentary, and a link to the original source. Article excerpts are limited to 100 words when published. A source link preserves context; it does not independently verify a claim.
