We obsessed over efficiency so you get state-of-the-art accuracy without the bloat, cost, or latency.
Blazing fast
Our tiny model runs in under 50ms on average. Real-time OCR that doesn't keep your users waiting.
STEM-native
Built from the ground up for math, physics, chemistry, and engineering. LaTeX output that just works.
Chemistry-first
Molecular structures to SMILES, reaction equations to LaTeX, chemical diagrams to structured data. Built for drug discovery and research.
Tables & documents
Complex tables, multi-column layouts, and full-page documents. Preserves structure perfectly.
Handwriting ready
Messy lecture notes? Whiteboard photos? Our model handles real-world handwriting with ease.
Dead-simple API
One endpoint. One line of code. Get LaTeX, Markdown, MathML, or plain text back instantly.
10x cheaper
Our efficient model means lower costs for you. Pay a fraction of what other OCR services charge.

\int_{0}^{\pi} \sin(x) \, dx = 2One API call. That's it.
No SDKs to install, no complex configuration. Send an image, get back structured text — including SMILES for molecular structures. Works with every language and framework.
Chemistry-native outputs
SMILES, MOL/SDF, InChI for structures. LaTeX for equations. Choose what fits your pipeline.
Batch processing
Send up to 100 images in a single request for bulk screening workflows.
Webhooks & streaming
Get results pushed to you in real-time with server-sent events.

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.”
“The SMILES output from molecular diagrams is a game-changer. We pipe structure images straight into our docking pipeline — no manual redrawing.”
“We process 50K student submissions daily. Tiny OCR handles our volume effortlessly and the handwriting recognition is best-in-class.”
“The API is so clean. I had it integrated into our app in under 10 minutes. Genuinely impressed.”
“We digitized 20 years of handwritten lab notebooks in a weekend. Chemical equations, structures, all of it — straight to searchable SMILES and LaTeX.”
