Faithful rendering is the product.
Don't mess with the report. Render it untouched inside a sandboxed iframe. The chrome around it should never compete with what's inside.
Mission
Sharing work-in-progress should feel like sharing a Google Doc.
AI tools and dashboards spit out HTML. Sending it as a file is a regression. Comma fixes that.
Principles
04 / 0402 / 04
Commenting is the signature gesture.
Anchored, contextual feedback is the reason this tool exists. The accent color belongs to marks and actions, not decoration.
03 / 04
The tool should disappear.
Earned familiarity, not theatrics. Users notice when chrome competes with content. Our chrome is a structural, drafting-table sensibility: honest to what the product actually is.
04 / 04
Speed is a feature.
A measuring instrument loads instantly. Latency is a tax on every collaboration. We pay it ourselves so you don't.
What we won’t build
The shape of a tool is also the shape of what it refuses to be.
- No.01We won't reformat your HTML “for you.”
- No.02We won't bundle a dashboard builder. Bring your own report.
- No.03We won't lock comments behind a paywall.
