Translation
Move prompts across models with versions tailored to the target provider.

Model-specific rewrites

Adapt prompts for a new provider without rebuilding your workflow from scratch.

Provider-aware prompt style

Generate prompts that better match how each model family responds in practice.

Versioned prompt variants

Keep multiple translated versions inside one project and compare them over time.

Start Translating
Evaluation
Benchmark prompt quality with repeatable runs, clear scores, and output-level visibility.

Side-by-side results

Compare outputs case by case so regressions and weak spots stand out fast.

Clear quality scoring

Track semantic and structural performance with a score you can use to decide quickly.

Standalone evaluation

Run repeatable prompt benchmarks and get useful signal without extra process overhead.

Start Evaluating
Workflow

A tighter loop from prompt to signal

Run evaluations quickly, see where quality breaks down, and improve with less guesswork.

Define the prompt to test

Add your prompt, build realistic test cases, and set the quality bar up front.

Run evaluation instantly

Benchmark your prompt against real scenarios and capture quality signals fast.

Review what changed

See scores, output diffs, and weak cases in one place so issues are obvious.

Improve and rerun

Refine the prompt, rerun the suite, and keep the version that performs best.

Prompt portability
Move working prompts to a new model without rebuilding everything from zero.
Quality checkpoints
Catch weak responses early with explicit test cases and scores you can trust.
Project timeline
Keep prompt revisions, evaluation runs, and translation history organized in one place.
