Redline is a collaborative review tool for HTML documents. Reviewers annotate and suggest changes. You queue them, apply them with AI, and publish a new version — all in one place.
How it works
Upload an HTML document. Redline renders it exactly as it appears, inside the review interface.
Share a review link with stakeholders — no account required. They annotate, comment, and suggest changes directly in the document.
Review all suggestions in a structured queue. Accept, reject, or modify each one before applying. Nothing gets applied without your sign-off.
AI applies your queued changes and generates a new version. Each version is stored and versioned — so you can always go back.
Key features
Everything teams need to go from messy feedback to a clean revised document.
Your document renders exactly as it looks in a browser, with your original styles preserved. Reviewers see what they're actually commenting on.
All feedback collects in a structured queue — like a cart of changes to apply. Review everything before anything gets changed. You stay in control.
When you're ready, Claude AI applies your queued changes to the document and produces a new, clean version. No manual editing of HTML required.
Every published version is stored. See what changed between v1 and v3, share a specific version with a stakeholder, or roll back if needed.
Share review links with anyone — clients, legal, external stakeholders. No account or login required. Token-based access keeps it secure and simple.
Auto-populated from a comment in your HTML file, the Document Brief gives reviewers the context they need: what this document is for, what kind of feedback is useful.
