Integrations

Verist wraps AI tools – it doesn't replace them.

How it works

Any external tool – LLM provider, extraction library, classifier – runs inside a defineStep. Verist captures artifacts, enables replay, and produces diffs when you recompute with a new model or prompt.

your tool (extraction, classification, generation)
        ↓
  defineStep({ run })   ← Verist wraps the call
        ↓
  artifacts captured    ← input, output, events logged
        ↓
  recompute + diff      ← see what changed after a model upgrade

What Verist adds

Concern	Your tool provides	Verist adds
Extraction quality	Prompts, models, grounding	–
Replay	–	Reproduce past runs from artifacts
Diff	–	See exactly what changed
Audit trail	–	Structured events per execution
Human overrides	–	Overlay layer survives recompute
Identity-aware diff	–	keyBy for stable array matching

Available integrations

• LangExtract – structured extraction with source grounding

More integrations coming soon. Any tool that runs inside a step gets replay and diff automatically.
