PromptEval vs Promptotype

PromptEval is a web and API SaaS platform for evaluating and optimizing large-language-model prompts. It assigns a reproducible score from 0 to 100, with diagnostics covering clarity, specificity, structure and robustness, then identifies issues, warnings, strengths and targeted fixes. A token optimizer compresses prompts while preserving intent and reports the reduction percentage. Its versioned library keeps prompt history, score changes and diffs. The A/B Playground compares two prompts across as many as seven criteria using a user-provided API key. An official GitHub Action can fail pull requests after score drops, contradictions or production regressions. Pro and Team users can serve prompts by slug through an API endpoint, with changes taking effect in about 60 seconds. Plans include a free tier, Basic at $9 a month, Pro at $19 a month, and custom-priced Team.

Promptotype is a web-based platform for developing and evaluating structured tasks for language models. Its playground lets users build prompt templates, configure models, and work with function calling. Test queries can include expected JSON schemas or values; a model query can fill in an expected result. Users can run prompts against collections, from smaller development sets to larger checks for production readiness. The platform also provides run and test history, scheduled automated tests with email summaries, and automatic fine-tuned model creation from query collections. A JSON Schema Editor supports schemas compatible with the OpenAI API’s json_schema response_format. The free plan is free. Basic costs $6 a month and adds libraries for templates, configurations, and queries, plus collection testing. Professional costs $10 a month and includes 60 days of history, fine-tuning, and one weekly scheduled run. Team features are contact-based. The maker is Baionic, LLC, which lists a New York, New York mailing address.
