Ask AMPM First, Pay Later
AI tools change prices monthly, free tiers get slashed overnight. What AMPM does is simple: check every AI tool’s pricing, free allowance, and Chinese support — and lay it all out in front of you.
You don’t need to open one website after another — see if the free plan is enough first, only pay if it isn’t.
Two Cats, Day and Night Patrol
The name AMPM comes from two cats: AM is AMO, golden sun on the chest, day shift; PM is PIMI, crescent moon on the chest, night shift.
Names, emblems, day-and-night monitoring — all three connected. From morning to night, whenever an AI tool’s price or free tier changes, it won’t escape these two cats’ eyes.


Why You Can Trust the Data
- Every entry shows its last-verified date — you know exactly when the price was confirmed, not “some unknown time ago.”
- Every entry shows its last verification date. We re-check official sites on an ongoing basis. — we don’t write an article and let it rot.
- Verification gates block incomplete data — if data is missing or malformed, our gate scripts reject it. We’d rather show nothing than show wrong numbers.
- If we can’t find it, we say so — information not published on the official site, we don’t guess, don’t make up.
