AI transparency

BlinkWrite uses AI to draft writing suggestions. You decide if BlinkWrite inserts a suggestion.

Text watermark

BlinkWrite adds an imperceptible statistical watermark while its self-hosted model generates text. The watermark does not add hidden characters or visible labels.

The watermark changes the probability of model tokens. A detector can measure the resulting statistical pattern.

Detection

Use the BlinkWrite watermark detector to inspect text. The detector produces a digitally signed JSON report.

The report contains:

• A SHA-256 hash of the submitted text
• The report time
• The detector and watermark versions
• The model identifier
• The score, threshold, and result
• The public signing-key identifier

BlinkWrite does not retain text that you submit to the detector.

Result limits

The detector needs at least 200 tokens for a reliable result. Short text gives an inconclusive result.

Translation, paraphrasing, and substantial editing can weaken the watermark. A negative result does not prove human authorship.

A detected watermark is evidence that the text matches BlinkWrite's watermark. It does not identify a person or a request.

Public signing keys

Each downloaded report contains a compact JWS signature. The detector publishes the current and retired public signing keys.
