FAQ
How does prompt versioning work?
Every time you save a prompt, PromptDiff creates a new version with a timestamp. You can compare any two versions side-by-side and attach performance scores to each run.
Which AI providers are supported?
PromptDiff is provider-agnostic. Paste prompts from OpenAI, Anthropic, Gemini, or any other model — we track the text and metrics, not the API calls.
Can I cancel my subscription?
Yes, cancel anytime from your billing portal. You keep access until the end of your billing period and can export all your data before leaving.
