What is Plain?

Support platform betting hard on an agentic AI responder as the default first touch

Plain is a customer-support tool whose recent work is dominated by two AI agents: Ari (autonomous responder) and Sidekick (assistant). In this window Ari was rebuilt from a classify-and-handoff workflow into an agentic, search-first default first responder, suggested replies were moved onto the same engine, and Sidekick gained tool integrations and a Slack presence. Platform plumbing (Attio, Linear, workflows) continues alongside.

What is Twilio?

Twilio expands EU data residency and cross-channel messaging while building an AI-agent layer

Twilio is shipping steadily across voice and messaging, with a clear push on EU data residency (Studio, TaskRouter, and SMS now in the Ireland IE1 region) and richer cross-channel messaging primitives (unified V3 typing indicators across RCS/WhatsApp/AMB, Elastic SIP call forwarding with caller-ID preservation). In parallel it is standing up an AI-agent SDK layer (Agent Connect) just behind the recent window.

Support platform betting hard on an agentic AI responder as the default first touch

◆ Current state

Plain is a customer-support tool whose recent work is dominated by two AI agents: Ari (autonomous responder) and Sidekick (assistant). In this window Ari was rebuilt from a classify-and-handoff workflow into an agentic, search-first default first responder, suggested replies were moved onto the same engine, and Sidekick gained tool integrations and a Slack presence. Platform plumbing (Attio, Linear, workflows) continues alongside.

◆ Where it's heading

The direction is unmistakably AI-native support: make the agent the default first responder, give it agentic search and tool access, and meet users where they work (Slack, the composer, workflows). The non-AI releases — CRM connectors, workflow actions, API additions — increasingly exist to feed context to that agent.

◆ Prediction

Expect Ari and Sidekick to keep absorbing the support workflow — more tool integrations, deeper autonomy, and tighter loops between suggested replies and autonomous sends — with platform/API work continuing to supply the context they rely on.

Twilio expands EU data residency and cross-channel messaging while building an AI-agent layer

◆ Current state

Twilio is shipping steadily across voice and messaging, with a clear push on EU data residency (Studio, TaskRouter, and SMS now in the Ireland IE1 region) and richer cross-channel messaging primitives (unified V3 typing indicators across RCS/WhatsApp/AMB, Elastic SIP call forwarding with caller-ID preservation). In parallel it is standing up an AI-agent SDK layer (Agent Connect) just behind the recent window.

◆ Where it's heading

Two arcs: regional/compliance buildout (EU residency GA for SMS, private-beta Studio/TaskRouter in IE1) and channel enrichment toward agentic communication (typing indicators, Apple Messages for Business, Agent Connect's multi-channel orchestration with memory). Infrastructure-upgrade and cipher/deprecation notices round out the operational maturity.

◆ Prediction

Expect more regional GA milestones and continued investment in the AI-agent SDK (Agent Connect) and rich-messaging channels, pushing Twilio further toward an orchestration layer for AI-driven customer conversations.
