Normalize exact characters
Replace unusual spaces, remove invisible carriers and preserve meaningful script marks.
Clean invisible Unicode from ChatGPT, Claude, Gemini and other AI text in your browser. Use a fast edge rewrite for statistical token patterns, and strip image metadata on-device.
A browser-side view of writing regularity and phrase distribution.
This is a surface-pattern comparison, not proof of authorship or a model-specific watermark detector.
Replace unusual spaces, remove invisible carriers and preserve meaningful script marks.
Use Cloudflare's fast edge model only when you click — with no model download. Numbers, links, emails, quotes and code are locked. Sections that fail checks stay unchanged.
NoMark combines an AI text watermark remover, invisible character checker and AI image metadata remover in one private web app. There is no sign-up, and the exact scanner shows what changed before you copy or download the result.
Clean pasted AI text from supported hidden characters, suspicious formatting and statistical token patterns while preserving visible meaning and protected facts.
Find zero-width spaces, word joiners, Unicode tags, bidirectional controls and mixed-script lookalikes with an inspectable character report.
Strip common EXIF, GPS, XMP, IPTC and C2PA Content Credentials from JPEG, PNG and WebP images through local browser processing.
Paste the text into NoMark, review the character report, then choose Remove AI watermark. NoMark removes supported invisible Unicode and can optionally rewrite statistical token patterns while protecting facts such as numbers, links, email addresses, quotes and code.
NoMark detects exact hidden Unicode, zero-width characters, directional controls and mixed-script lookalikes. Those findings are not proof of AI authorship. Statistical text watermarks cannot be confirmed by scanning Unicode alone.
NoMark rebuilds JPEG, PNG and WebP images in your browser to remove common file metadata including EXIF, GPS, XMP, IPTC and C2PA containers. It does not remove visible logos or robust watermarks encoded into image pixels, such as SynthID-style signals.
Yes. NoMark is free and requires no account. Exact Unicode scanning and image processing happen on your device. The optional text rewrite runs only after you click the removal button and uses a fast edge model.
