Captcha Helper

Recognize common static text and one-step arithmetic CAPTCHAs offline, then fill safely or ask for confirmation.

Captcha Helper is a privacy-focused browser extension that recognizes common static CAPTCHAs directly on your device. It is designed for users who frequently access administration panels, information systems, internal tools, and other websites that require repeated CAPTCHA input. The extension supports common CAPTCHA formats, including digits, English letters, alphanumeric strings, and one-step integer arithmetic. Recognition can be initiated through the extension popup, an image context-menu command, or a configured mouse action. When Captcha Helper finds a unique and suitable input field, it can fill in a high-confidence result. It never clicks login, confirmation, or submit buttons, and it never submits forms automatically. If the recognition result or input-field match is uncertain, the extension abstains and leaves the decision to the user. All recognition runs locally inside the browser using the model bundled with the extension. CAPTCHA images, recognition results, website permissions, extension settings, and diagnostic records are not uploaded to the developer or any third-party server. Users remain in control of website access. You can grant access to all websites once, or enable the extension only for selected websites you regularly use. Authorized and disabled websites can be reviewed and managed at any time from the settings page. Captcha Helper requires no account, contains no advertising, uses no telemetry, and does not track browsing activity. Local diagnostic records are sanitized, limited in number, and can be cleared by the user. Supported CAPTCHA formats: • Digits • English letters • Alphanumeric strings • One-step integer addition, subtraction, multiplication, and division Captcha Helper does not support image-selection challenges, sliders, puzzles, animated CAPTCHAs, behavioral verification, or other interactive challenges. CAPTCHA styles vary between websites, so the extension cannot guarantee recognition of every image. When confidence is insufficient, it prioritizes safety and avoids automatic filling.
