Everything you need to keep your reference data clean.

Semantic matching

AI finds the closest canonical record even when the input looks nothing like it on the surface.

Correction cache

Every human review becomes a cache entry. The same messy input never asks a reviewer twice.

Batch orchestration

Resolve a million rows with parallel embedding, vector search, and LLM calls — or stream matches one at a time.

Confidence tiers

Auto-accept above a threshold you set. Route ambiguous matches to your review queue. No-match stays no-match.

Reviewer workflow

A tight review queue with side-by-side diffs, keyboard shortcuts, and bulk actions. Built for the people who actually do the work.

Full audit trail

Every decision — cache hit, model verdict, human override — is logged with timestamps and actor.

Six deterministic steps from messy input to canonical record.

Each stage is observable, cacheable, and overridable. The fast path is cache; the slow path is a few hundred milliseconds end-to-end.

  1. 01

    Normalize

    Lowercase, strip punctuation, collapse whitespace. The input is rebuilt as a canonical search string before we look at it.

  2. 02

    Cache

    Hit the correction cache first. Prior human decisions short-circuit the rest of the pipeline with zero model calls.

    Embed

    Titan v2 generates a 1024-dimensional vector for the input. Cached entity embeddings are pre-computed.

    Vector search

    Postgres pgvector returns the top-k nearest entities by cosine distance. Typically k=12.

    Disambiguate

    Claude Sonnet scores the candidates against your field weights and domain glossary. Structured output, no parsing.

  6. 06

    Decide

    Auto-accept above your threshold, route to review if ambiguous, emit no_match if nothing clears the floor.

Built for the messiest reference data in your stack.

ERP migration
