Paste any HTML
Reports from dashboards, notebooks, and AI tools render exactly as written, in an isolated sandbox. Charts and scripts included.
Comment in context
Select any text, in a paragraph or a table cell, and pin a thread to it. Highlights stay anchored. Resolve when it's done.
Share like a doc
Invite editors, commenters, or viewers by email, or hand out a link. Anyone with the link gets their own identity.
Safe by default
Uploaded HTML runs in an opaque-origin sandbox with no access to your account. Faithful rendering, zero exposure.
Watch a report go from upload to comment to share.
One continuous take. Real product, no mockups: drop in an HTML report, mark a line, drop a comment, watch a teammate drop their reply live, then hand out a link.
Stop screenshotting reports into Slack.
Create your first reportWe believe sharing work-in-progress should feel like sharing a Google Doc.

Comma is built by Nadir Tech LLC. We're a small team that believes sharing work-in-progress should be as natural as sharing a Google Doc, even when the work is raw HTML from a notebook, dashboard, or AI tool. The product is a measuring instrument, not a notebook; that's the bar we hold.
