Frequently asked questions

What do I get back?
text is the rewrite. patternsFound lists the patterns found in your text, remainingPatterns what still sounded generated in the first draft, and draft holds that draft.
What does a call cost?
About 32 credits for a short text: the rules take about 7,400 tokens per call and tokens cost 4 credits per started 1,000. gpt-6.1-terra costs twice as much.
Does it get text past AI detectors?
That is not its goal, and detectors may still flag the result. It edits for human readers.
