Inovai / Document extraction
Stop retyping mill test certificates.
We extract heats, chemistry and mechanical properties from the PDF and check them against ČSN EN standards. Your people only verify and approve.
Problem
Certificates come from dozens of suppliers, each with a different table and language. Retyping is slow and errors are found late.
What we’ll do
We extract the data by heat and compare it with the limits of the standard by steel grade, thickness and delivery condition.
Result
The operator only confirms. A value outside the standard is visible before you put the material into stock. More than 10,000 certificates in operation at Favex.
From attachment to finished data
Four steps, a human approves the export.

01 / 05
Same value, different thickness, different limit.
The check works with context and says why it flagged a value.
ČSN EN standardsChemical and mechanical limits for the supported steel grades, thicknesses and delivery conditions. We verify the scope for your operation during the test.
Each heat separatelyChemistry and mechanical properties stay with the specific heat. A missing heat or a mismatch between sections is visible.
A missing standard is visibleWhen a standard is not in the database, the system says so. It does not replace it with an estimate based on another standard.
Data in your ERP’s format.
We verify the fields, code lists and import method during roll-out.
XML export to ERPIn operation at Favex. Codes from the ERP code list, split by dimension, original PDF attached.
Other ERPsFor another system, we design an adapter based on its import options: XML, CSV or API.
Email, PDF and archiveIntake from a Microsoft 365 mailbox or via IMAP, manual upload and batch import of history. REST API for custom integrations.
Result first, then the decision.
Send us 5 to 10 certificates from different suppliers by arrangement, scans or complex documents are welcome.
Test on your certificatesExtracted data, check results and an overview of corrections and limitations on your documents. NDA up front; we delete the samples after the test.
PilotAn agreed sample of suppliers and standards, a review interface and verification of accuracy and operator time.
OperationOutput quality monitoring, rule management and support when documents change.
Can it handle scans and different suppliers?
Handles text PDFs and scans, multi-page certificates and different languages. So include both typical and difficult documents from several suppliers in the test.
How long does extraction take?
At Favex, automatic extraction takes 28 seconds on average. Human review and ERP import are further steps.
Does a green rating mean a flawless certificate?
No. It means the configured checks found no discrepancy. A responsible employee always approves the result before export.
Where are the documents processed?
Depending on data sensitivity: in the cloud in the EU, on a dedicated server, or entirely in your infrastructure with a local model. We agree the rules for data transfer and retention before the test.
Does the check replace physical verification of the material?
No. It checks the data in the certificate against the standard. A responsible employee decides about the material.
