Your AI assistant for UBL & Peppol e-invoicing

Upload an invoice and describe what you need in plain language. The assistant converts, creates, validates and extracts your UBL and Peppol invoices in seconds, right inside the chat.

What can the UBL assistant do?

Attach an invoice, then describe what you need. Tap any example to drop it into the chat, edit it, and press send.

Convert legacy invoices

Drop in a plain PDF or a CII XML file and get a compliant UBL invoice back.

Create an invoice from scratch

Describe the invoice in plain language and the assistant builds a compliant UBL file for you.

Validate compliance

Check any invoice against EN 16931 and the Peppol BIS 3.0 rules, with a clear pass or fail and the exact issues listed.

Extract structured data

Pull the machine-readable UBL XML out of a PDF invoice, ready to reuse in your systems.

Getting the best results

Attach a file

Use the paperclip in the chat to add a PDF or UBL XML invoice, then tell the assistant what to do with it.

Be specific

Mention the UBL customization or fields you care about, for example the Peppol BIS 3.0 profile or a payment due date.

Download in the chat

The assistant returns a finished UBL file you can download straight from the conversation.
