GLYPH
GLYPH tucks a short note inside ordinary text using invisible characters, so the text looks completely normal but quietly carries your note. You can also paste text someone sent you to reveal a hidden note, or to check whether a message has an invisible watermark in it. Revealing is free; hiding a note needs a Sovereign pass.
Please read: GLYPH is obfuscation, not encryption. It hides a note in plain sight, but anyone who knows to look can pull it back out, and copying the text through some apps will strip the hidden part. Do not use it for anything that needs to stay secret, and do not use it to slip content past a filter or a person. For real secrecy, use encryption.

Hide a note
GLYPH runs entirely in your browser and never uploads anything. It encodes your note as invisible zero-width characters mixed into the cover text. This is a lightweight way to watermark your own writing or leave a note in plain sight, not a security tool: the hidden text is easy to detect and extract, and it will not survive every copy-paste. Never rely on it to protect anything sensitive.
