Frequently Asked Questions
What is AI Checker & Shield and is it free?
AI Checker & Shield is a free browser tool that detects AI-generated images, masks sensitive data, stamps watermarks on ID documents, and anonymizes faces. No registration, payment, or installation required; all operations run directly in your browser.
Do my uploaded files go to servers?
No. None of the images, texts, or documents you upload reach our servers. All analysis, masking, and editing operations run client-side (only in your browser). When processing is complete, data is instantly erased from memory. You can verify this yourself with DevTools.
How are AI-generated images detected?
The Image Detective examines EXIF metadata analysis, pixel-level noise maps, and compression artifacts. It compares AI signatures such as DALL-E, Midjourney, and Stable Diffusion against real camera metadata to produce a probability score. Results are not definitive legal proof but provide professional guidance.
What does Prompt Shield do and which data does it mask?
Prompt Shield is a privacy tool that automatically detects and masks sensitive data in text and code. It finds email addresses, phone numbers, IP addresses, credit card numbers, IBANs, API keys, JWT tokens, MAC addresses, national ID numbers, passwords, and sensitive URL parameters in seconds. Full mask, partial mask, or highlight-only modes are available.
Why is the ID Stamp (watermark) important and how does it work?
It stamps cross-purpose watermarks on your ID photocopies to protect against digital fraud. For example, text like "FOR ABC BANK LOAN APPLICATION ONLY" makes it difficult for your document to be used for other purposes. The watermark is applied semi-transparently across the entire image and is downloadable.
Who is Face Blur for?
It is designed for journalists, photographers, parents, event organizers, and anyone who values privacy. It automatically detects faces in photos and applies blur or pixel (mosaic) effects. It anonymizes faces in children's photos, protest images, or corporate events where individuals have not given consent.
What does client-side mean?
"Client-side" means all operations are performed on your computer and in your browser. Data is not sent over the internet to another server, not processed in the cloud, and not shared with third parties. You can even disconnect from the internet while using the site; the tools will continue to work.
Is there a file size limit for image analysis?
There is no strict limit because processing happens in your browser's memory. However, very large files (over 50MB) or very high-resolution images (20MP+) may cause temporary slowdowns depending on your browser's performance. JPG, PNG, and WebP formats are supported.
