PromptPerfect – Open-source prompt optimizer for LLMs
Handy prompt refiner, but prompt engineering itself is becoming obsolete with better base models.

Yet another prompt optimizer when PromptPerfect and built-in model tools already exist.

The motivation was simple: most prompts people write are poorly structured, which often leads to unstable AI responses.
So I implemented a Proposer–Critic–Verifier optimization pipeline.
Proposer restructures the prompt. Critic evaluates clarity, structure, and task definition. Verifier checks consistency. Arbiter detects convergence.
The system runs several iterations and produces a structured prompt specification.
It usually takes around 30–40 seconds to run the full optimization loop.
The tool also includes: • prompt quality analysis • explain mode • version history • prompt diff viewer

Would love to hear if people building AI tools find something like this useful.
