How does the version history work?
Every prompt save becomes a version you can reopen, so you never lose the wording that last worked — the undo history a plain text file does not give you.
What does the regression check do?
It runs the new prompt against saved cases and flags behavior changes, so a tweak that quietly degrades output is caught before it ships.
Can I roll back a bad edit?
Yes. One click restores a prior version, turning a broken prompt from an incident into a thirty-second revert.
Who treats prompts like code?
Teams where prompts are shipped artifacts, not scratch notes — the same discipline you already apply to source, applied to the text that drives the agent.
Where AgentPrompt reaches its limits
What AgentPrompt does is narrow: Version and regression-test your agent prompts. It watches or grades agents, but a dashboard is not a kill switch. Keep a human accountable for what the agent actually does.

What does AgentPrompt do?
AgentPrompt keeps every version of your agent prompts, shows a clean diff between any two, and runs a regression check so a prompt edit never silently breaks agent behavior.
How much does AgentPrompt cost?
Plans start at $29/month (billed $290/year). Open the live tool for the current plan before versioning your prompts.
Who is AgentPrompt for?
AgentPrompt is built for teams shipping or operating AI agents who need this exact job done: Version and regression-test your agent prompts.
How does the regression check work?
It runs the updated prompt against saved evaluation cases and flags behavior changes, catching a quiet quality drop before release.
Can I compare two versions?
Yes. It renders a clean diff between any two saved versions so you see exactly what changed and why behavior shifted.
Is rollback one click?
Yes. You can restore a previous prompt version instantly, turning a bad edit from an incident into a quick revert.
What will AgentPrompt miss?
Not a guarantee of rankings or ad performance. Treat generated copy and briefs as drafts to review, not published-ready without a human pass.
