Could this workfor your team?
Show us the documents you process and the information you need. Together, we’ll work out how HEROextractor fits into your workflows.
Discuss your use caseYour examples. Your workflows.
Which documents can we extract data from automatically?
Examples include invoices, delivery notes, contracts, technical drawings and emails. HEROextractor processes digital documents, scans, images and text, including printed and handwritten content. Representative samples are the best way to assess how well it works with your documents.
Can we choose which data fields to extract?
Yes. You decide which information you need and can add or adjust fields, descriptions and table columns. Alongside individual values, HEROextractor supports tables and matrices, for example for invoice line items, quantities or measurements.
Do we need to train HEROextractor before getting started?
For supported standard document types, you can start with the existing templates. If information is missing or your particular documents need better recognition, you can add fields and rules and train models using your examples. This lets you improve the results that matter to your daily work.
What happens if a value is read incorrectly?
You can review and correct extracted values alongside the original document. Rules and comparisons with your master data help identify implausible values. Together, we define the checks your process needs before the data is passed on.
Can HEROextractor work with our existing software?
Extracted information is available as structured data for further processing. REST interfaces can connect applications and databases and compare values with existing master data. We work with you to establish which connection your software supports and where each piece of data should go.
Where are our documents processed?
Processing is carried out entirely by DOCSHERO. All services run 100% in the EU on servers rented by DOCSHERO. No external apps or AI providers are involved in processing.
Can we test HEROextractor with our own documents?
Yes, without signing up, in the “Try it yourself” section on this page. Upload a PDF, image, text file, e-invoice or XML/JSON file, select the document type and adjust the fields if needed. Then review the results alongside the original. You can also request a personal demo to discuss your specific workflows.
Do the online demo limits also apply in production?
No. The free online demo allows files up to 1 MB, up to 10 pages and 16 documents per person per hour. This protects the public demo from overload. These limits do not apply in production, where we tailor processing to your document volumes and workflows.
Can HEROextractor also suggest cost centres?
Yes. You provide your cost centres and describe which expenses belong to each. Based on the extracted information, AI suggests an allocation – for example, office supplies to cost centre 100 “Administration” or machine spare parts to 200 “Production”. The cost centre does not need to appear in the document: it is suggested using your criteria and can be reviewed before further processing.
Are e-invoices supported and checked?
Yes. HEROextractor supports e-invoices such as XRechnung and ZUGFeRD/Factur-X. It reads the structured invoice data and checks the information against your business rules. In the verifier, you can review the results alongside the document and correct them before further processing.
