Base Prompt
Variant
How it works
From draft to
production-ready
Build a reliable prompt workflow: iterate safely, test across models, and ship improvements with clarity.
Create and collaborate on prompts
Write, organize, and share prompts in one workspace - so your team stays aligned from the very first draft.
Branch prompts into variants
Iterate systematically by branching prompts into variants for different approaches, while keeping a clear history of every change.
Run experiments across LLMs
Compare prompt variants across multiple LLMs - choose models and set iterations.
Rate outcomes and decide on variants
Rate outcomes together and compare metrics - then promote the best prompt variant.
