AI CAPTCHA recognition API for reCAPTCHA, Cloudflare and more
Handles popular challenge types including reCAPTCHA, hCaptcha, Cloudflare Turnstile, and image or OCR-based recognition.
A straightforward HTTP API lets developers submit challenges and receive solution tokens programmatically.
Extensions and browser-automation hooks make it easier to solve challenges inside real browsing sessions.
Image recognition plus OCR models are applied to text and picture CAPTCHAs as well as interactive puzzles.
Humanize AI text and check how human it reads
Rewrites AI-generated drafts with natural phrasing, rhythm and flow, and lets you pick light, medium or aggressive rewriting depending on how much change you want.
Scan text before and after humanizing to see which sentences still look machine-written, with colour-coded sentence-by-sentence highlights.
Click any sentence to see alternative rewrite options and fine-tune the output until it matches your own voice.
Returns humanized text in seconds, with word limits per input ranging from 1,000 words on the free plan up to 5,000 words on paid tiers.
