WHY GRINDA

Where Ordinary OCR Stops, Grinda Keeps Going

Four real worries that make teams hesitate on document AI — here's how Grinda handles each. Tap a worry to see how.

"Every vendor's form is different — do we have to set it up for each one?"

Ordinary OCR

Requires registering coordinates/templates per format, and re-setup whenever a new form arrives.

Grinda Document AI

Understands the document's meaning to find fields — no templates. Even a form it's never seen is processed as-is.

FAQ

Document OCR: Top Questions Before Adopting

Recognition performance depends on document quality and type. That's why, before adoption, you can see extraction results on your own real documents, and in production a workflow where humans review only low-confidence fields keeps final data quality high.

FREE EXTRACTION TEST

Ten of Your Documents Are Enough to See the Results Yourself

Start with a short request — you send samples only after we've agreed on how to share them. See the results for yourself before you decide on adoption.

  1. Send a request

    Tell us about your document types and volume. No documents are attached at this step.

  2. Agree on how to share samples

    Within 1 business day, we contact you to define the fields to extract and explain how to send samples securely.

  3. We run the extraction

    We run extraction on your samples. The closer they are to what you actually receive, the better the results predict production.

  4. Get the results report

    Field-level results with confidence scores, what can be automated, and a proposed review and integration setup.

Before you send samples

  • 5–10 pages per document type is enough — include tricky ones with handwriting, stamps or poor scans.
  • You can mask personal or sensitive values before sending.
  • If you need an NDA, we sign it before receiving any samples.
  • Your documents are used only for this test and never to train external models.
