Trust your data, faster Similarity API

Fuzzy match hundreds of thousands of records in minutes—not hours—with a highly configurable, easy-to-set-up string similarity API.

Designed for Speed, Control & Trust

Why data teams choose us...

Lightning Fast

A matching engine that scales exponentially better, making real-time deduplication of millions of records practical.

Zero Setup Required

Simple REST API—no clusters, projects, or pipelines to spin up. Copy → paste → fuzzy-match in minutes.

Highly Configurable

Fine-tune thresholds and behavior without the math. Defaults work; knobs are there if you need them.

Flexible, Transparent Pricing

Pay-as-you-go, tiered, or enterprise—per-row pricing with no hidden fees.

Batteries Included

From data cleaning to match confidence, the heavy lifting is done. You focus on decisions, not wiring.

Security & Privacy by Design

Data stays in memory, encrypted in transit, and is never stored or shared.

Performance Benchmark

15× faster than the next best option

We benchmarked Similarity API against common fuzzy string matching libraries. The results? It's 15× faster than the fastest alternative on a 10K-record dataset — and it only scales from there!
