Before you buy either
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
SheetMagic watch-outs
- The credit counter is platform orchestration, not model API usage — easy to misread as a model cap
- Plan A is single-seat; a small team wants Plan B
- Redeem the code within 60 days of purchase
