Frequently asked questions

Does it validate JSON?

Completely — it runs in your browser, so your JSON never leaves your device (unlike many online formatters).

One licence key, pasted into any CYZOR tool. Today it does three things: drops the CYZOR line from PDFs you send for signature, takes CYZOR branding off your forms and adds CSV export, and switches on the AI rewrite in the resume builder.
