Batch OCR

Upload a whole batch in the app, or send files via the API, an SDK, or n8n. Batches are processed in parallel, and any document can be re-run from the OCR step without uploading it again.

Works with PDFs, images, Office files, and emails, in more than 50 languages. Hover over a tile to see it at work.

OCR gives you the text. Klaaro gives you the data.

Plain OCR tools are great at turning a document into machine-readable text, but you still need to find the relevant data manually. Klaaro automatically recognizes what kind of document you have uploaded and extracts the fields you need as structured data for your ERP.

How OCR works in Klaaro

  1. Drop files into the app, or send them from your systems via API, SDK, webhook, or n8n. Batches are processed in parallel.

    Integrations

  2. Each page goes to the OCR model that fits it: print, handwriting, or tables. The layout of the page stays intact.

    Document parsing

  3. Classification and data extraction pick up where OCR ends, so the text turns into checked data for your systems.
