01 — Inject / Watermark
Insert an invisible character at a fixed interval to watermark or fingerprint text (e.g. to trace which copy of a document was leaked). Fully reversible with Scan and Clean. Optionally hide a short secret message using zero-width steganography.
02 — Scan / Detect
Paste any text to reveal every invisible or suspicious character — zero-width formatting, bidirectional overrides (Trojan Source), unusual spaces and control codes. Each is highlighted inline and listed with its code point. Also extracts any hidden steganographic message.
03 — Clean / Sanitize
Strip hidden and dangerous characters from untrusted text before storing, publishing or committing it. Ideal for sanitizing pasted content, user input and source code (defends against Trojan Source attacks).
04 — Character Library
A searchable reference of special Unicode characters — invisible formatters, bidi controls, unusual spaces and handy symbols. Click Copy to grab any character. Filter by name, code point or category.
