Loved by developers, researchers & chemists

Join thousands who switched to faster, cheaper, more accurate OCR — from drug discovery to education.

Tiny OCR is absurdly fast. I switched from Mathpix and cut my API costs by 80% while getting the same accuracy.

ML Researcher, Stanford
The SMILES output from molecular diagrams is a game-changer. We pipe structure images straight into our docking pipeline — no manual redrawing.
JO
Dr. James Okafor
Computational Chemist, Novartis
We process 50K student submissions daily. Tiny OCR handles our volume effortlessly and the handwriting recognition is best-in-class.

CTO, GradeBot
The API is so clean. I had it integrated into our app in under 10 minutes. Genuinely impressed.

Aiko Tanaka
Senior Engineer, EduTech Inc
We digitized 20 years of handwritten lab notebooks in a weekend. Chemical equations, structures, all of it — straight to searchable SMILES and LaTeX.
