What this receipt proves

✓

Signature valid

This receipt was signed by Figleaf's server

✓

These words were chosen by AI, not by the sender

The sender wrote a message with a related meaning, but the specific words were generated by Figleaf's server — the sender did not choose them

–

Sender may have seen the output before sending

The sender used the extension or compose tool, which shows the blurred text before sending. The blur is still AI-generated and verifiable.

Dial settings

Distortion 1/10 — minimal Wordsmithing 5/10 — moderate

Distortion — how far the output drifts from what was said. Higher = more cover, more unpredictability. Wordsmithing — how much the AI reshapes based on author and audience context.

Trust

This receipt is signed by Figleaf's server. You are trusting that Figleaf performed the re-encoding as described. The sender provided a message; the server transformed it using AI with the dial settings shown above, and the sender did not control the specific words in the output.
