Free up to 200 words — 3 runs per week, no sign-up required. Longer runs are billed at $1 per 10,000 words from your Valence credit balance.
Edit either side, then run it. Results vary by model and stealth settings.
Two layers, one rewrite
The humanizer runs an LLM pass against a curated pattern catalog, then a deterministic post-processor that targets the statistical signals AI detectors actually score on.
29-pattern catalog
Significance inflation, AI vocabulary words, copula avoidance, rule-of-three, em-dash overuse, and more — from Wikipedia's Signs of AI writing guide.
Stealth post-processing
Aggressive vocab sweep, sentence-length variation, paragraph reshuffling, and optional zero-width character shield. All off, light, or full per request.
Multi-model
Gemini 2.5 Flash / Pro, Claude Opus 4.7 and Sonnet 4.5. Falls back to a local rewriter when no keys are configured.
Free + pay-as-you-go
Short runs (up to 200 words) are free, 3 per week. Longer ones are metered at $1 per 10,000 words against your Valence credit balance. No subscriptions, no monthly minimums.
