THE ACCURACY GAP

A single misplaced field breaks the whole form.

Generic OCR guesses at boundaries and types. We benchmark against 50,000+ real government, finance, and healthcare forms — and publish the method.

FIG.3 — ANATOMY OF A DETECTED FIELD

Every field comes back fully described.

Not just a box on a page. Each detected field is returned with everything you need to render, validate, and trust it.

BOUNDARYA pixel-exact bounding box, so the widget lands precisely on the line.
TYPEOne of 14 field types, mapped to the correct interactive widget.
CONFIDENCEA 0–1 score per field, so you can flag anything below your threshold.
FORMATA semantic hint — ssn, currency, date — for instant validation.

"We replaced a three-week manual templating process with one API call. The detection is genuinely better than what our team did by hand."

"At 40,000 government forms a month, a 1% field-error rate was unacceptable. Create a Fillable PDF closed the gap."

FAQ

Questions developers ask first.

Everything else lives in the docs — or ask us directly.

What input formats do you accept?+

Any PDF — scanned, exported from Word or InDesign, or born-digital. Send a file upload or a URL; we normalize it before detection.

How is accuracy measured?+

Field-by-field against a hand-labeled corpus of 50,213 real government, finance, and healthcare forms. We publish the methodology and re-run it every quarter.

What do I get back?+

A standards-compliant AcroForm PDF plus a typed JSON schema describing every field: name, type, format, bounding box, tab order, and a confidence score.

How do you handle sensitive documents?+

Encrypted in transit and at rest, and every uploaded file is permanently deleted within 24 hours. A zero-retention mode is available on Scale.

Is there a rate limit?+

Each plan has a requests-per-minute limit. If you need higher throughput for large jobs, contact us and we'll raise it.
