Frequently Asked Questions
Распознает ли он рукописный русский текст?
Нет. Tesseract Russian model supports printed text only. Handwritten Russian (especially pre-Soviet пропись cursive) is not reliably recognised. Specialised handwriting models are on our roadmap.
Can it read Soviet-era typewritten documents?
Yes, with 85-92% accuracy depending on typewriter clarity. Moscow-standard typewriters from 1950-1990 (Yatran, Ukraina) produce consistent output that Tesseract handles well. Very faded ribbons or multi-carbon copies drop to 70-80%.
Дореволюционный русский шрифт поддерживается?
Да, with caveats. Pre-1918 Russian orthography includes Ѣ (yat), І (decimal i), Ѳ (fita), Ѵ (izhitsa) — these are in Unicode and the model recognises them at ~80% accuracy on clean scans. Old church Slavonic scripts are not supported.
How accurate on Russian newspapers?
On clean printed Russian (Коммерсантъ, Ведомости, РБК, Российская газета), accuracy is 94-97%. Kommersant's complex typography drops slightly; tabloid-style papers with decorative fonts may fall to 88-92%.
Мои документы в безопасности?
Абсолютно. Вся обработка происходит в вашем браузере — паспорт РФ, загранпаспорт, СНИЛС, ИНН, водительское удостоверение never leave your device. Privacy is enforced by architecture, not policy.
