The Prompt Lab
Validate, Analyse and Score your Prompts
The Prompt Lab helps you write better AI prompts before sending them to ChatGPT, Claude, Gemini, or other LLMs. Our prompt linting engine analyzes prompts for clarity, context, constraints, structure, and potential issues, then provides actionable suggestions to improve quality. The goal is simple: fewer retries, more consistent AI responses, and better prompt engineering through intelligent prompt evaluation.
Thanks for checking out The Prompt Lab!
This is a side project we're actively building and validating with the community. The current release is an early version focused on prompt linting and evaluation, so there's still plenty of room to improve.
We're especially interested in understanding:
* Does the prompt evaluation feel useful?
* What features would make you use it regularly?
* What's missing or confusing?
Every suggestion, critique, and idea helps shape the roadmap. Thanks for taking the time to try it out—we genuinely appreciate your feedback, and there are many improvements on the way!
