Still testing AI the hard way? Manually?

•

Spending hours collecting good test scenarios

Hours wasted

•

Manually testing, waiting for AI responses and checking outputs

Hundreds of times

•

Documenting what worked and what didn't in spreadsheets

Lost in spreadsheets

•

Running same tests accross different LLM providers (OpenAI, Anthropic, etc.)

Double work

•

When you update your system prompt? Test everything again

Back to square one

Paste your AI's instructions

To test your LLM app, we need your prompts. Large Language Model (LLM) powered applications are driven by prompts — clear, specific instructions that shape AI behavior.
