Hi, I'm Angus, the creator of FinLang.
I built this because categorising financial transactions with "black box" ML models is becoming a massive compliance risk, especially with the EU AI Act's 2026 deadline.
FinLang is the alternative: a simple, high-performance rules engine that is 100% deterministic, auditable, and transparent.
It includes: • finlang — apply rules at 24k rows/sec • finlang-discover — find uncategorised patterns • finlang-suggest — auto-build exact rules
The engine is self-hosted, no telemetry, and fully auditable.
I'd really appreciate feedback.
