The consumer SMS agent moment: a guide to the agents you can text

What changed: TechCrunch published a long rundown of consumer-facing AI agents that live in messaging apps and SMS — cataloging providers that can run multi-step tasks, keep memory, connect to email/calendars, and act proactively on your behalf.

Why it matters: Founders and small businesses who need low-friction customer touchpoints can prototype agent-driven services without building full apps — agents reachable by text remove distribution friction and let companies automate scheduling, follow-ups, reservations, and simple commerce.

Try/watch: Pilot one SMS-based agent for a single, revenue-linked workflow (booking, returns, or lead qualification) and instrument acceptance, auth friction, and complaint rates before widening use.

Dessa: Block’s local, full‑duplex voice model that moves voice agents off the cloud

What changed: Block released details and demos of Dessa, a speech-to-speech model that runs locally (consumer‑grade GPUs) and produces more natural cadence, emotion, and pauses — a capability pitched for on‑device voice agents and conversational experiences.

Why it matters: If you sell voice experiences (retail kiosks, phone-based support, or in-store assistants), a local full‑duplex model can cut runtime costs, reduce cloud‑data exposure, and improve latency — but it also raises the bar for social‑engineering risks because the agent’s voice can sound convincingly human.

Try/watch: Run a constrained on‑device pilot where the agent can only surface information or hand off to a human; measure task completion, user trust, and any increase in fraud or social‑engineering attempts.
