What is PromptGround?
Prompts managed and tested across models with one API key.
Who is PromptGround best for?
PromptGround is best for developers who keep prompts out of code and test them on several models.
Prompts kept out of the code
Prompts live in a web editor and your app calls them through the API, so changing a prompt does not need a new deploy.
Picking a model before shipping
You can run the same prompt with variables on different models and compare token use, response time and cost for each run.
Mixed technical and non-technical teams
Team members are free and unlimited, so marketers or product managers can edit production prompts in a shared workspace with roles and permissions.
Watching AI spend by project
Run logs record every call and show spending per project, which helps when several apps share one key.
