Basic ($1.99/week or $5.99/month) bumps your weekly usage budget well above Free and unlocks reasoning, agent mode, custom instructions, plus the advanced models (GPT-5.4, Gemini 3.1 Pro, Claude Sonnet 4.6, Grok 4.20). Pro ($3.49/week or $9.99/month) pushes the budget higher again and adds Privacy Guard, web search, and the URL-fetch tool.

Chrome on desktop, nothing else. The extension depends on Chrome-only APIs that Firefox, Safari, and Edge do not implement, and there is no mobile version.

Visit the activation page, select Pro, and enter your email. If you already have an active subscription, you'll only be charged for the remaining time in your billing period.

Open the CaptureAI extension popup, go to Settings, and click “Manage Billing”. Cancel anytime from there. Your access stays active until the end of the billing period you already paid for.

Privacy Guard is a Pro feature. It hides the signals your browser sends that exam platforms use to spot tab switches, focus loss, and extension activity, and it blocks the scripts those platforms run to sniff for installed study tools.

No. The screenshot is read on your own computer first. When the text comes through clearly, only the text reaches the AI and the image never leaves your device. If the text is too blurry to trust, the image goes up so the model can read it, and we drop it as soon as the answer comes back.

Yes, within 7 days of purchase. We look at each request individually. Email support@captureai.dev with your order details and we will get back to you.

Check your spam or junk folder for a message from captureai.dev. Keys send the moment payment clears. If nothing turns up after 10 minutes, email support@captureai.dev with your receipt and we will resend the key.

Capture just the question, not the whole page. If the text is small, zoom in before you drag the box. You can also switch models from the floating panel or the sidebar — the advanced models (GPT-5.4, Gemini 3.1 Pro, Claude Sonnet 4.6, Grok 4.20) generally handle messy wording better than the Quick tier.

Every plan has a weekly cost budget that resets on a 7-day rolling window, plus a smaller 6-hour session budget. Free runs out the fastest. Basic and Pro have much higher caps. If you keep bumping the Basic ceiling, upgrade to Pro for the highest budget.

Chrome itself blocks every extension on its internal pages and on the Chrome Web Store, so CaptureAI cannot run there. If an exam platform looks like it is sniffing for extensions, switch on Privacy Guard (Pro) and try the page again.

That message almost always means a payment failed and the subscription lapsed. Open the CaptureAI extension popup, go to Settings, and click “Manage Billing”. The billing portal will show the current status and let you update the card on file.

No. Locked-down browsers are stand-alone applications that disable Chrome extensions entirely, so CaptureAI never loads there. The extension only works inside regular Chrome. If your exam runs in Chrome and only uses webcam proctoring, the sidebar chat and capture flow still work, and Privacy Guard (Pro) hides extension activity from the page itself.

Start at chrome://extensions and confirm the extension is enabled. Then press Ctrl+Shift+E to force the panel open. Certain pages on Blackboard and Canvas try to block extensions, and switching on Privacy Guard (Pro) usually gets things working there.
