Invoices in.
Audit-grade postings out.

Drop an invoice. Watch a multi-agent ADK pipeline extract it deterministically with AILANG Parse, validate against the vendor master, decide a posting, and surface every step as an inspectable artifact.

How it works

Every decision, inspectable.

No video, no slide deck. Every claim the agent makes shows up in a Card you can click into.

  1. 01

    Pick a sample invoice

    Three fixtures pre-loaded — DOCX, ODT, EML — so you can run the pipeline without finding your own file. Or drop your own invoice in.

  2. 02

    Watch the four-agent pipeline run

    Intake → Extract → Validate → Post. Each step emits a structured A2UI Card the moment it completes — no JSON-staring required.

  3. 03

    Open the audit view

    Click any specialist chip to see exactly which tools fired, what input each agent saw, and what it returned. Every decision is inspectable.
