How the Hindi captcha solver works
- Reads the Devanagari. A recognition model trained on Hindi captchas reads the number word letter by letter, including vowel signs, halant and nukta, even when the portal draws each character separately.
- Snaps to a real number. The reading is matched against every Hindi number word from 0 to 100, so a single blurred letter can't turn बयालीस (42) into nonsense.
- Computes the answer. The operator and digit are read too, and the result comes back in
text, with what was computed inexpression(e.g.42-6). - Tells you when to trust it.
reliable: falsemeans refresh the captcha. That answer isn't charged.

Frequently asked questions
Can an API solve Hindi captchas?
Yes. Send the captcha image with math: true and hindi: true. The API reads the Hindi number word in Devanagari, the operator and the digit, then returns the computed answer, ready to type. It takes about 25 ms.
Which Hindi numbers does it understand?
Every Hindi number word from शून्य (0) to सौ (100), including common alternative spellings such as पन्द्रह, चवालीस and पैंतीस. The full list is on this page.

Not yet. The second operand is read as Western digits (0–9), which is how the portals we support show it. Contact us if your captchas use Devanagari numerals.

Which portals use Hindi captchas?
Hindi-number arithmetic captchas appear on Indian government sites, such as state land-records portals, where the question reads like ‘इकतीस + 6 = ?’. The solver was built and measured on these captchas.
