Which one is for you
Choose 1minAI if…
- You're casual-to-moderate users paying for two or more AI subscriptions who want one credit pool with rollover.
- Your use case is all-in-one AI subscription or multi-model chat.
Choose PromptBuilder if…

- Your use case is prompt engineering or multi-model prompting.
Before you buy either
1minAI watch-outs
- Team credits are shared first-come-first-served — a heavy user can drain the pool, so solo is the cleanest fit
- Per-feature credit costs aren't symmetric; video and TTS burn faster than text
- It's a wrapper — new models arrive after 1minAI wires them up
PromptBuilder watch-outs
- Team collaboration is on the roadmap — solo workflow only at launch
- The 'assistant request' counter is separate from generations; heavy iterators may want the Pro tier
- Codes must be redeemed within 60 days of purchase
