About Twilio
What is Twilio?
Twilio is a cloud communications platform that provides APIs and AI-powered tools for businesses to build personalized, cross-channel customer experiences. It solves the problem of fragmented customer conversations by unifying SMS, voice, email, WhatsApp, RCS, and chat in one platform.
Who is it for?
Twilio is ideal for developers, product teams, and enterprises building customer-facing apps—from contact centers and marketing campaigns to authentication flows. It is not for non-technical users seeking a ready-made, no-code communication app.

Twilio’s Conversation Memory and Intelligence features enable context-aware interactions that feel natural and continuous.
