Built for STEM. Built for accessibility.

Every feature designed to turn handwritten scientific content into documents that work for everyone.

AI-Powered Recognition

State-of-the-art OCR trained on millions of STEM documents. Handles messy handwriting, faded ink, and complex notation with 99%+ accuracy on printed content.

WCAG 2.1 AA Compliant

Every output meets WCAG 2.1 Level AA standards. Proper heading hierarchy, alt text for every equation and diagram, tagged document structure, and verified reading order.

Under 30 Seconds

Most single-page documents convert in under 10 seconds. No waiting, no queuing โ€” upload and download in moments.

Secure & Private

Documents are encrypted in transit and at rest. Files are automatically deleted after conversion โ€” never stored, never used for training.

MathML & LaTeX Output

Equations are rendered in MathML for maximum screen reader compatibility. LaTeX source is also embedded for easy editing and re-use in academic workflows.

Accessibility Report

Every converted document includes a detailed accessibility report. Heading structure, alt text coverage, reading order verification, and color contrast checks โ€” all in one summary.

Simple, pay-as-you-go pricing

Your first 3 conversions are free. Then purchase credit packs โ€” the more you buy, the less each conversion costs.
