What Heurio does

Annotate webpages for design reviews, bug reports and guided heuristic evaluations.

Documented features

The official listing documents the capabilities below. Compare the functions you need with the available platform and paid-feature information before installing. These are the developer’s descriptions, not independent performance or security test results.

“This is a guided manual review, not an automated scan.”
“Click any element and pin a comment - add a note, a suggestion, a severity level, and (optionally) a heuristic guideline reference (Nielsen, WCAG, and more).”
“Pin comments straight on the live preview as you build, then use the copy-as-prompt button so your AI agent knows exactly what to fix - and share the project link so anyone helping you build can leave feedback too.”
“Invite others to the project, or share the project link.”

Installing and opening Heurio

Open the Chrome Web Store link, confirm Heurio - Website Review, Heuristic Evaluation & Vibe Coding Feedback and the publisher Zoltan Bartha, then select Add to Chrome. Read the requested permissions before confirming. After installation, Chrome’s Extensions menu provides access to the extension; pinning its toolbar icon is optional. To disable or remove it later, use Chrome’s Manage Extensions page.

The manifest declares a toolbar action. Use its toolbar entry to open the extension’s action.

Using the documented workflow

Start with the operation that matches your task. The following actions are documented in the official listing; they are separate usage options, not a sequence that every user must complete. For controls not named here, consult https://www.heurio.co/support rather than assuming a particular button or menu exists.

“You choose what to flag, one click at a time - Heurio doesn't scan the page for you automatically.”
“Leave structured feedback on a live build, track what's fixed, and compare implementation against your Figma design.”
“Suggest copy changes directly on the live page, in context - not in a separate doc that goes out of sync.”
“Run real-time, shared reviews during a brainstorm or workshop, with everyone commenting on the same live site at once.”

Platforms, version and interface languages

Verified store editions: Chrome. The captured version is 2.6.08.07, with an update date of 2026-08-10. Version numbers and release timing can differ between stores. Only the browser-store buttons shown here were verified. A shared browser engine does not establish a separate official store edition.

The official store lists 1 interface languages. The supported-language tags on this page come from that product metadata; they are separate from the eight languages available for this guide. Check the current store if a particular language is essential to your workflow.

Price and paid features

The developer describes a free tier, trial or free version alongside paid features. Check the official website for the current feature limits and price in your region. Installing the browser package and subscribing to a connected service are separate actions; a browser-store button alone does not establish which paid features are included.

Permissions, privacy and practical limits

The published extension manifest lists these API permissions: storage, activeTab, tabs. These are declared capabilities, not proof of what data the developer actually collects. Review Chrome’s installation prompt and the developer’s privacy policy (https://www.heurio.co/privacy-policy) before granting access.

Chrome’s extension details let you inspect site access and disable the extension. If an expected control does not appear, check that the extension is enabled and that the current site is one supported in its description. Do not extend access to every site merely to troubleshoot a single website.
