What it is

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.
