Every tool and feature on the platform, in one list. Start free - no credit card required.
Takes text you already have and rewrites it so it reads the way a person would naturally write: varied sentence structure, adjusted word choice, and smoother rhythm, while keeping what the text actually says. Five writing styles cover casual, formal, and in-between tones, and grammar is smoothed as the text is rewritten.
Estimates how likely a passage is machine-generated and shows the evidence behind the number: an overall score together with sentence-level detail, so you can judge each sentence yourself rather than trusting a single figure. Our own detector test found a human-written paragraph scoring 99% AI, which is exactly why the sentence signals are shown alongside any score.
Checks images through pixel analysis and metadata inspection to estimate whether an image was generated by AI. Upload an image and review the reported signals.
Focused tools for the smaller jobs that come up in everyday writing:
The humanizer and detector are available as HTTP endpoints for use in your own applications and workflows. Request and response formats are documented on the API docs page. API access is included with the Pro and Business plans.
A free account keeps your work in one place: past rewrites and detector reports are available from the dashboard. The Free plan covers limited monthly usage of the humanizer and detector with no credit card required; paid plans raise the limits and unlock detailed reports and API access. See the pricing page for the full comparison.
Rewrites preserve meaning: the goal is to change how text sounds, not the facts, arguments, or claims behind it. Detection is presented as an estimate, not a verdict, with the underlying signals visible. Terms like perplexity and burstiness are explained in plain language in the AI detection glossary.
