A little clarity.
A lot of possibility.

A FRESH PERSPECTIVE

Your project is ready.
Let’s bring it to life.

CopyReplace selection

Review your words. Keep your voice.

An illustrative rewrite. Results vary by text and model.

LESS COPYING. MORE WRITING.

A small extension.
A smoother writing routine.

Keep the context of your page and bring only the passage you want to work on.

Start with a selection

Select text on an ordinary web page, then open Check AI from the right-click menu. You can also paste text directly into the extension.

Check, then consider

Review an AI detection signal alongside its limitations. A result supports your review; it cannot prove who wrote a passage.

Refine with intention

Humanize your passage, review the result, then copy it or replace your selection in a supported text field. You decide what to keep.

READY IN A FEW STEPS

Make room for
better words.

The beta uses Chrome’s “Load unpacked” option. Install it once, then pin Check AI beside your address bar.

  4. 04

    Choose your first passage

    Select text, right-click and choose Check AI, or paste into its panel. Review the word count and tool availability before you run it.

A deliberate action.
Every time.

The extension processes the text you choose. It does not run AI checks as you browse. Submitting a request sends your chosen text to external AI processing services and uses your account allowance. Provider details are available in the extension privacy information.

Where does it work?

You can select text on ordinary web pages and replace selections in supported textareas, text inputs and standard contenteditable fields. Some editors handle text differently: Google Docs, canvas-based editors, embedded frames and protected Chrome pages are not supported in this beta. Copy and paste is available as a fallback.

Do I need a separate subscription?

No separate extension subscription is needed. AI requests use your Check AI detection or rewriting word allowance. If you need more words, eligible paid accounts can add a credit pack from My account. Service availability is shown before processing.

How long does the connection last?

The extension keeps a temporary account session in Chrome’s session storage. Reconnect when it expires or after restarting Chrome. You can disconnect from the extension at any time.

Is this a Chrome Web Store release?

This is a downloadable beta with manual installation. There is no Chrome Web Store listing yet. To update, download the latest ZIP, replace the extracted files and choose Reload for Check AI on Chrome’s extensions page.

Keep your train of thought.
Bring Check AI along.
