Vid · free
See what reaches your agent.
Paste a message, a document or a prompt. Vid undoes the disguises an attacker hides text behind — invisible characters, look-alike letters, Base64 and other encodings, text tucked inside JSON, XML or Markdown — and shows you what is really there. It shows; it does not block. Stopping is Perun.
This runs entirely in your browser. The text you paste never leaves your computer — the same as the Vid you download.

Vid is the free edition: it watches and shows. Perun, the paid edition, reads the meaning of a message and stops the attack.
