Noteback: add and share feedback notes directly on HTML docs
Noteback is a Chrome browser extension that lets you leave comments and notes directly on HTML documents while viewing them. You can then share those notes with others without needing a separate tool.
When reviewing a web page or an HTML document, people usually have to copy text into emails or separate note apps to send feedback. Noteback removes that extra step. Once installed in Chrome, you can click on any part of an HTML page, add a note, and share the annotated view with teammates or collaborators.
This can speed up document review cycles for small teams or solo projects. However, it has no direct connection to AI agent development or reducing API token costs, so its relevance to that use case is limited.
Key points
- Installs as a Chrome browser extension — no separate app needed
