How it works
Simplex wraps form complexity into a simple API. You build workflows in an interactive editor, then run them deterministically in production.- Custom-built web agents — agents write and execute code to fill forms, handling dropdowns, branching logic, and multi-step flows
- Automatic form mapping — discovers which question branches might appear based on your input data
- Variables and test data — integrates with your existing databases and context engines
- Structured outputs — get structured data back via API (approval status, quote amounts, confirmation numbers)
- Deterministic production execution — workflows run as code (fast, cheap, reliable), not LLM inference
