What PromptTools is
PromptTools is an open-source toolkit designed to give developers a free and open set of tools for testing and experimenting with prompts. It offers interfaces and methods that let you use familiar code and notebook environments to evaluate prompts. You run experiments in a notebook, look at the output, and judge how well a prompt works. You can then turn those assessments into unit tests and add them to your CI/CD workflows. A core idea of the project is running code locally, which matters for work that touches sensitive data.
What you can do with it
Here is what it helps you do:
- Run prompt experiments in a notebook and assess the output
- Turn assessment results into unit tests
- Add those tests to CI/CD so prompts stay reliable
- Keep code running on your own machine for privacy
Who it is for
It is built for a few groups:
- Developers building with language models
- Teams that want prompt checks inside CI/CD
- Projects that need to keep code and data local
What to watch out for
PromptTools is a developer tool, so there is a learning cost if you are not comfortable with code and notebooks. You install and run it yourself, and there is no hosted service doing the work for you. It is focused on testing and experimenting with prompts rather than being a general chat interface. Because it is open source, features and support depend on the project and community, so check the current docs before you build on it. Start with a small sample to confirm the output meets your expectations before processing the full batch.
