Broad integration capabilities with SSO, APIs, and developer tools.

Unpredictable API billing and cost factors that may not be immediately visible in initial pricing, with significant discrepancies between reported usage and actual charges.
Commercially unreasonable legal terms, including an 'AS IS' warranty and severely limited liability cap.
Default opt-in for data training on consumer tiers, creating a high risk of corporate IP leakage.
Mobile app performance issues and bugs (voice-to-text, audio playback, slow loading).
Opaque data retention and deletion policies, creating compliance gaps.
