Limitations
- Steep price ladder, from $12.99 a month to $40,000 a year
- Billed by conversation minutes, so cost scales with how much people talk to it
- Zapier integration needs a separate Zapier subscription
Tavus
Strengths
- Real-time conversational video, not just pre-rendered clips
- Full developer API across video, audio and conversation
- Free Basic plan with 25 conversational video minutes
