Deliberate capture
Inspect selected text, article text or a pasted draft only when you ask the extension to run.
Chrome extension · Version 1.2.3
Free AI Checker Chrome Extension
A free AI checker Chrome extension that inspects selected page text or a pasted draft locally. Not an AI detector Chrome extension that runs a trained model by default: it uses named, model-free checks with no host permissions, remote code or analytics.
Product features
AI content checker for Chrome: selected text and pasted drafts, checked locally
The extension waits for text you deliberately select, capture or paste, then runs the packaged checks in a local Worker. It does not request permanent access to the sites you visit, and the inspected copy is not retained by default.
Local Worker checks
Unicode, lookalike, writing-pattern and protected-content checks run inside the packaged extension.
Hash-only receipts
Export a method record without silently retaining the inspected draft.
Tested features
Chrome versions, permissions and interaction checks
Supported Chrome versions
The exact package has been exercised in the declared minimum Chrome version and the current Chrome for Testing release.
Privacy and permissions
Package inspection confirms no host permissions, remote code, analytics or undeclared network route.
Rendered interaction
Keyboard, narrow viewport, service-worker restart, storage clearing and accessibility checks are included in the release gate.
Requirements
Before installing the Chrome extension
Confirm the supported Chrome version. Restricted browser pages cannot expose their content to an extension, so paste the text into the extension when a page cannot be captured.
- Google Chrome 145 or later is the declared minimum for version 1.2.3.
- Restricted browser pages can be checked by pasting text into the extension.
- Select or paste only the content you want the extension to inspect.
Frequently asked questions
Free AI checker Chrome extension questions
Does the extension read every page I visit?
No. Version 1.2.3 has no host permissions. It inspects only text you deliberately select, capture or paste through its own controls.
Does it send page text to Opace?
No. The named checks run in the packaged extension, with no analytics, remote code or content-bearing network route.
What text can I inspect?
Select or capture text on a normal web page, or paste a draft into the extension. Restricted browser pages can still be checked by pasting the text.
Is this an AI detector Chrome extension?
Not in the trained-model sense. It is a free AI checker Chrome extension that runs named, model-free checks locally: invisible characters, writing patterns and protected facts, with no host permissions, remote code or analytics.
Where should I report a problem?
Use the Opace contact page and include the product version, platform version, expected behaviour and the smallest safe reproduction. Do not include draft text, authentication tokens, personal data or customer information. Contact Opace.
