Prompt testing and AI evals

Test prompts, compare models, and ship AI with confidence.

Why it works

Built to make AI decisions feel calm, legible, and defensible.

Evaluate with clarity

Bring prompts, datasets, and graders into one place so model decisions stop living in scattered docs.

See tradeoffs directly

Compare quality, latency, and spend in the same view instead of guessing from separate dashboards.

Ship with evidence

Promote only the prompt or model version that holds up against the cases your product actually sees.

How teams use it

A simple workflow for a problem that is usually messy.

The best part of Anthropic’s homepage is not decoration. It is restraint. This version moves in that direction: fewer gimmicks, stronger typography, softer tones, and clearer product storytelling.

Prompt library

Version the exact tasks that matter.

Store production prompts, benchmark examples, and edge cases together so your team can evaluate real work, not toy demos.

Structured evals

Run rigorous comparisons across models.

Use exact match, regex, and model-based judges to score outputs consistently as providers and prompts change.

Release decisions

Know what improved before you ship.

Review score movement, latency, and cost in one calm interface built for product and engineering teams.

Get started

This direction is quieter, more premium, and closer to Anthropic’s editorial feel while still presenting your own product clearly.
