# Heurio Documentation — Chrome extension & web app user guide

> Heurio documentation: install the Chrome extension, pin comments on live websites, run heuristic evaluations, share projects, and manage teams in the Heurio web app.

Each page below is also available as plain markdown by appending `.md` to its URL (for example `/docs/onboarding/getting-started.md`).

## [Onboarding](https://www.heurio.co/docs/onboarding)

Install the Heurio Chrome extension and run your first website review in minutes.

- [Getting Started](https://www.heurio.co/docs/onboarding/getting-started) — Install the Heurio Chrome extension, pin it to your toolbar, leave comments on any live website, and invite teammates — all in under 5 minutes.

## [How to use Heurio](https://www.heurio.co/docs/how-to-use-heurio)

Use the Heurio extension and web app to pin comments, switch views, change screen sizes, run heuristic evaluations, and invite teammates.

- [Add a Comment on a Website](https://www.heurio.co/docs/how-to-use-heurio/add-a-comment-on-a-website) — Pin a structured comment (a 'heurio') on any live website element with the Heurio Chrome extension — including a note, suggestion, severity, and optional guideline reference.
- [Invite Team Members](https://www.heurio.co/docs/how-to-use-heurio/invite-team-members) — Invite teammates to your Heurio project by email with 'Can edit' or 'Can view' permissions — from either the Chrome extension or the web app — for shared visual feedback on any live website.
- [Browser & Comment View](https://www.heurio.co/docs/how-to-use-heurio/browser-and-comment-view) — Switch between Comment View (click any element to add a heurio) and Browser View (navigate the live site with all heurios visible) in the Heurio Chrome extension.
- [Heuristic Evaluation](https://www.heurio.co/docs/how-to-use-heurio/heuristic-evaluation) — Run a heuristic evaluation on any live website using Heurio's built-in guidelines — Nielsen, Dieter Rams, Shneiderman, Weinschenk & Barker, and more — directly from the Chrome extension.
- [Change Screen Size](https://www.heurio.co/docs/how-to-use-heurio/change-screen-size) — Review your website at desktop, tablet, or mobile sizes from inside the Heurio extension. Each heurio also captures the exact viewport it was created at for context.
- [Extension & Web App](https://www.heurio.co/docs/how-to-use-heurio/extension-and-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.
- [Heurio in Incognito Mode](https://www.heurio.co/docs/how-to-use-heurio/heurio-in-incognito-mode) — Enable the Heurio Chrome extension in Incognito mode to review websites in private browsing sessions — useful for staging environments, logged-out flows, and isolated profiles.

## [Share & Collaborate](https://www.heurio.co/docs/share-and-collaborate)

Share Heurio projects, manage teams and seats, use comment threads, and export reports for stakeholders.

- [Share Project Link](https://www.heurio.co/docs/share-and-collaborate/share-project-link) — Share a Heurio project with a copyable link, set it as private, public, or organization-only, and optionally protect it with a password — from the extension or the web app.
- [Export Project](https://www.heurio.co/docs/share-and-collaborate/export-project) — Export your Heurio project as a PDF or CSV report — filter by date range, creator, page, or status, and optionally redact creator info before sharing with stakeholders.
- [Use Comment Threads](https://www.heurio.co/docs/share-and-collaborate/use-comment-threads) — Reply, @-mention, attach files, and react with emojis underneath any Heurio comment. Comment threads turn each heurio into a focused discussion you can resolve as a team.
- [Manage Your Team](https://www.heurio.co/docs/share-and-collaborate/manage-your-team) — Group Heurio users into teams (Developers, UX Research, QA, Copywriting…) and add an entire team to a project in one move. Available on Heurio's Organization plan.
- [Assign Seats](https://www.heurio.co/docs/share-and-collaborate/assign-seats) — Assign and unassign Heurio seats to activate or deactivate users in your organization — all from one admin panel, on the Heurio Organization plan.

## [Project Management](https://www.heurio.co/docs/project-management)

Track heurios across severity, kanban, and details views, review project analytics, and use organization admin features.

- [Severity View](https://www.heurio.co/docs/project-management/severity-view) — Heurio's Severity View groups every heurio by impact (Critical, High, Medium, Low, Neutral) so your team knows exactly which website issues to fix first.
- [Kanban View](https://www.heurio.co/docs/project-management/kanban-view) — Track heurios as cards on a Kanban board — drag them between status columns (To do, In progress, Done) for visual workflow management in any Heurio project.
- [Details View](https://www.heurio.co/docs/project-management/details-view) — Heurio's Details View walks through one heurio at a time, slide-style, so reviewers can focus on each comment, screenshot, and discussion thread without distractions.
- [Project Analytics](https://www.heurio.co/docs/project-management/project-analytics) — Heurio's Project Analytics summarizes a website review at a glance — total heurios, severity distribution, status breakdown, and progress over time — for status updates and stakeholder reports.
- [Admin Features](https://www.heurio.co/docs/project-management/admin-features) — Heurio's organization admin tools give you full visibility into every project in your workspace — track progress, manage access, and oversee feedback across teams. Available on the Organization plan.

## [Comment Details](https://www.heurio.co/docs/comment-heurio-details)

Configure each Heurio comment with severities, guidelines, custom heuristics, assignees, due dates, and captured device info.

- [Severities](https://www.heurio.co/docs/comment-heurio-details/severities) — Heurio's 5-level severity system (Neutral, Low, Medium, High, Critical) categorizes and prioritizes every heurio so the team knows which website issues to fix first.
- [Guidelines / Heuristics](https://www.heurio.co/docs/comment-heurio-details/guidelines-heuristics) — Reference a built-in heuristic guideline (Nielsen, Dieter Rams, Shneiderman, Weinschenk & Barker…) on any heurio. Set a global guideline per project or lock a specific rule for rule-by-rule reviews.
- [Custom Guidelines](https://www.heurio.co/docs/comment-heurio-details/custom-guidelines) — Build your own Heurio guideline — a custom checklist of rules that reflects your company's design system, content standards, or QA process — then run it on any live website.
- [Assignee](https://www.heurio.co/docs/comment-heurio-details/assignee) — Assign a heurio to a specific project member so every comment has a clear owner. Set the assignee from the extension or the web app and the project automatically tracks accountability.
- [Due Date](https://www.heurio.co/docs/comment-heurio-details/due-date) — Set a due date on any Heurio comment to keep reviews on schedule. Visible from both the Chrome extension and the web app, with sorting and filtering across project views.
- [Device Info](https://www.heurio.co/docs/comment-heurio-details/device-info) — Every Heurio comment automatically captures the timestamp, operating system, browser version, screen resolution, and DOM selector — so engineers can reproduce a bug without asking 'on what device?'.
