Мобилдик колдонмолор жана колдонмо ичиндеги сатып алуулар

sum.video iOS жана Android колдонмолору веб-сайт менен бирдей аккаунттарды жана кыскача баяндамаларды бөлүшөт, бирок төмөнкү айырмачылыктар менен:

  • Колдонмолордо сатылып алынган Pro жазылуулары Stripe тарабынан эмес, Apple App Store же Google Play тарабынан эсептелет.
  • Биз дүкөндүн квитанцияларын текшерүү жана жазылуу статусун аккаунтуңа шайкештештирүү үчүн RevenueCat'ты колдонобуз.
  • Мобилдик колдонмолор PostHog аналитикасын же жарнамалык көзөмөлдөө SDK'ларын камтыбайт.
  • Аккаунтуңду мобилдик колдонмодогу Аккаунттан же веб-сайттагы панелиңден жок кыла аласың. Бул sum.video'догу жеке аккаунт маалыматтарыңды жок кылат.
  • Аккаунтуңду жок кылуу активдүү App Store же Google Play жазылуусун жокко чыгарбайт. Аларды Apple ID же Google Play жазылуу жөндөөлөрүнөн жокко чыгар.

Claude жана ChatGPT коннекторлору

Эгер сиз Claude же ChatGPT'ди sum.video'го туташтырсаңыз, ал колдонмолор YouTube видео URL даректерин жана сиз коннектор аркылуу берген суроолорду жөнөтөт. Биз аларды учурдагы аккаунтуңуздун, жумалык кыскача баяндама квотаңыздын жана чат квотаңыздын астында иштетебиз. Биз Claude же ChatGPT сүйлөшүүңүздүн калганын албайбыз.
