FAQ
What counts as a prompt version?
Every time you save an edited prompt, a new version is created automatically. You can compare any two versions side-by-side with highlighted diffs and linked performance scores.
How are performance metrics tracked?
You log scores via our API or dashboard after each evaluation run. PromptDiff visualizes score trends across versions so you can pinpoint exactly which edit moved the needle.
Can my whole team use one workspace?
Yes. Each Pro workspace supports unlimited team members with role-based access — admins, editors, and viewers — so everyone stays in sync without stepping on each other's work.
