No document generators to configure, no hand-labelling. Synthony handles the synthesis — you focus on measuring your model.
Choose from bill of lading, customs invoice, health claim, remittance advice, and 40+ other schemas. Pass locale and any field overrides.
The API returns a rendered PDF alongside a JSON object with every extractable field value — exactly what your extraction model should output.
Feed the PDF to your model, compare extracted fields against ground truth. Compute precision, recall, and field-level accuracy at any scale.
Benchmark your extraction model against hundreds of realistic documents with known-good answers. Catch regressions before they reach production.
Seed your CI pipeline with repeatable, deterministic documents. No more brittle fixtures scraped from real data.
Populate demo tenants or QA databases with high-fidelity synthetic records. Safe to share, safe to delete.
Generate thousands of document-label pairs at scale. Label noise is zero — ground truth is computed at generation time.
Lock specific fields — shipper, patient, payer, port codes, currency — to your values. Synthony synthesises everything else around them.
Tears, blur, skew, stains, missing fields — dialed in via the API. 100% generative output, so use any names, IDs, or locations. No real PII required, no anonymisation step.
Request a pack and get multiple related documents with shared field values stitched across all of them — ready for multi-document extraction evals.
Synthony ships schemas for every major document type across freight, healthcare, and finance — each with realistic data variance and exact ground truth.
Generate Bill of Ladings, customs entries, and airway bills that mirror real-world variance — different carriers, port codes, Incoterms, and weight formats — with exact ground truth for every field.
Stress-test extraction across document layouts, fonts, and scan quality. Ground truth is always exact.
Generate Bills of Lading in MSC, Maersk, ONE, CMA CGM, and other carrier-specific layouts. Your model handles every variant.
Generate edge-case documents — missing port codes, split consignees, multi-currency invoices — to validate your rules engine.
Populate demo tenants with high-fidelity shipment data. Safe to share, safe to reset.
Same API, three entry points. Run Synthony from your terminal, wire it into CI for reproducible eval fixtures, or expose it to Claude Code and Codex over MCP.
Generate documents from the terminal. Ideal for ad-hoc test data or scripted batches piped into your local eval suite.
