In their own words
PromptPerfect
PromptPerfect is an open-source prompt optimizer from Beagle, available as a web app, Chrome extension, and API. In the web app, users submit a draft, choose an optimization mode, and receive rewritten text with an explanation of the changes. Modes include better, specific, cot, developer, research, beginner, product, and marketing. The Chrome extension is described as working on sites including ChatGPT and Gmail. Its API accepts a draft prompt and returns optimized text, an explanation, changes, the original text, provider, and model. Gemini, OpenAI, and Anthropic providers are supported. API keys can be supplied in the request body or as a Bearer token, with the Bearer token taking precedence. The homepage says keys stay in the browser and the project uses the MIT License. The Free plan costs nothing. Hosted Gemini anonymous callers share configured server-key quota.
