Now live — comment on any webpage

Leave A Note In The Margin Of Any Webpage.

SideQuill saves you time and mouse clicks by enabling faster and efficient asynchronous communication with your teammates across the web. It's like comments inside Google Docs, but for any website URL, public or gated — no more screenshots, no more "check the third paragraph on the page" over Slack.

Built For Teams Who Live On The Web

Everything you need to leave feedback, ask questions, and keep everyone in sync — without leaving the page you're looking at.

Comment On Any URL

Highlight anything on a public or gated webpage and leave a comment directly on it, just like in Google Docs.

Slack & Google Integration

Sign in with Slack or Google Workspace, tag teammates and channels, and get notified the moment someone mentions you.

Asynchronous By Design

Skip the live meeting. Leave a comment, tag who needs to see it, and let your team respond whenever works for them.
