Enterprise features like SSO and BAAs require a custom sales conversation rather than self-serve upgrade.
Free tier concurrency limits (2 TTS, 8 STT concurrent requests) may be restrictive for testing production-like load.

Planoly

The free mobile app tier is limited to 10 uploads per month, too low for active accounts.
Additional social sets and team seats require paid add-ons rather than being included at higher volumes.
Auto-posting to some platforms requires a push notification and manual tap to finish publishing rather than being fully automatic.
Advanced monetization and automation features are gated behind paid plans with no lower-cost equivalent.
