How to use Heurio
Extension & Web App
Heurio has two interfaces: a Chrome extension for capturing visual feedback on live websites and a web app for managing projects, teams, and reviews across the organization.
Use both: the Chrome extension is where you capture feedback on the live website. The web app at heurio.app is where you manage projects, assign owners, and report.

Frequently asked questions
- Do I need both the Chrome extension and the web app?
- No, but they complement each other. Use the extension to capture heurios directly on a live website, then use the web app to triage, assign, comment in threads, and export reports.
- Is the web app available without installing the extension?
- Yes. The Heurio web app at heurio.app works in any modern browser without an extension. You won't be able to create new pinned comments on a live site without the extension, but you can browse, comment, assign, and export existing projects.
- Do changes sync between the extension and the web app?
- Yes — in real time. Edit a heurio in the extension and the change appears immediately in the web app for everyone with access, and vice versa.
- Which one is better for QA and bug reporting?
- The extension is the right tool for capture: it pins exact elements, screenshots them, and records device info automatically. The web app is the right tool for triage and prioritization — sort by severity, filter by assignee, and export to PDF or CSV.
