Why teams choose Sempera

01

Complete product, not a toolkit

Sempera is voice AI that works out of the box. Twilio requires building the AI, conversation logic, and integrations from scratch.

02

No engineering team required

Build agents with Norm in plain English. Twilio requires a dedicated engineering team.

03

One vendor, one bill

$0.11 to $0.14/min for the full voice AI stack. With Twilio, you pay for telephony plus whatever AI services you build on top.

Twilio alternative FAQ

Sempera replaces the need to build voice AI on top of Twilio. If you're using Twilio to build AI phone agents, Sempera provides that as a complete platform. If you need programmable telephony for non-AI use cases (SMS, video, authentication), Twilio remains relevant.
