YesCaptcha Assistant is a browser extension for Chrome and Firefox. When a page shows a captcha, it sends the challenge to YesCaptcha for recognition and clicks automatically, with no code. The extension is free; recognition is charged at the price of the API types it uses, from the same account and balance as the API.

What it does

Section titled “What it does”
  • Recognizes and clicks the image challenges of reCAPTCHA v2, hCaptcha, FunCaptcha, AWS WAF and bCaptcha.
  • Text captchas: right-click the image and choose “Mark as captcha source”, then right-click the input box and choose “Put captcha answer here”; the extension reads the image and fills in the answer.
  • Each captcha type can be switched on or off in the settings, and click speed and retries can be adjusted.
  • Not every site can be passed; try it first.
