Captcha Helper - 本地验证码助手 作者： Wang Hongshuo

Captcha Helper recognizes common static text CAPTCHAs entirely on your device.

Supported CAPTCHA types:

• Digits
• Uppercase and lowercase English letters
• Alphanumeric strings
• One-step integer arithmetic using +, -, *, /, x, X, ×, or ÷

Start recognition from the extension popup, an image context menu, or the configured mouse shortcut. When the result is reliable and the page contains one matching empty input
field, Captcha Helper can fill it automatically. Low-confidence or ambiguous results are left for you to review.

Recognition and automatic filling are separate decisions. The extension never clicks a submit button, never submits a form, and does not replace existing input without
confirmation.

All recognition runs locally using the model bundled with the extension. CAPTCHA images and recognition results are not uploaded. There is no account, advertising, analytics,
telemetry, remote OCR service, or runtime model download.

You control website access. Grant access to all HTTP/HTTPS websites or maintain a list of selected sites. Settings, permission state, and sanitized diagnostic records remain in
your browser.
