What Promptotype is
Promptotype is a cloud-based platform for developing, testing, and iterating on structured tasks for large language models. Its playground lets users design prompt templates, configure models, and work with function calling. Users can define test queries with expected JSON schemas or values, then run a model query to populate an expected result. Collection testing applies prompts across groups of queries, from development sets to larger checks for production readiness. Promptotype also tracks test and run history, supports automated scheduled tests with email summaries, and can create fine-tuned models 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 is $6 a month and adds template, configuration, and query libraries plus collection testing. Professional is $10 a month and adds 60 days of history, fine-tuning, and one weekly scheduled run. Team collaboration and additional features are contact-based. The company says support is provided through online channels during regular business hours, without a guaranteed response time or outcome.
