Stop tweaking prompts.
Start optimizing them.

Build prompts, run experiments across models, auto-optimize with six algorithms, and simulate real conversations - all with evaluation scores at every step. No more guessing.

Create prompts from scratch, generate them from natural language, or start from templates. Every execution shows median latency, token counts, cost, and linked traces - so you know exactly how each change performs before it ships.

Open the workbench

Compare prompt versions, models, and parameter configs against the same dataset in one view. Automated evaluators score every response on accuracy, fluency, coherence, and your custom metrics - no more eyeballing outputs.

Run an experiment

Stop tweaking prompts by hand. Run ProTeGi, PromptWizard, GEPA, Meta-Prompt, or Bayesian Search to automatically generate, score, and refine prompt variants. Each algorithm targets different failure patterns - from targeted error fixing to full evolutionary optimization.

See the optimizers

Define agent personas and test scenarios - graph-based flows, scripted sequences, or dataset-driven cases. Run voice and text simulations against your agent, then evaluate every turn with automated scoring. Find failures before your users do.

Auto-optimize underperforming prompts

Paste a prompt that's not hitting your accuracy bar. Pick an optimizer - GEPA for production-grade, PromptWizard for creative tasks - and let it generate, score, and refine variants automatically.

Simulate customer conversations

Define personas and scenarios - then run voice or text simulations against your agent. Score every turn automatically. Ship agents that handle edge cases, not just the happy path.

Experiment and optimize

Run the prompt against your dataset. Compare model and config variants side-by-side with automated evaluation scores. If results aren't good enough, run an optimizer to automatically find better variants.
