AssemblyAI stopped selling transcription and started selling the whole voice agent.
AssemblyAI shipped a Voice Agent API that delivers speech understanding, LLM reasoning, and voice generation over a single WebSocket at one $4.50/hr rate, built on its own models. Around it, streaming speaker diarization got an accuracy upgrade with per-word labels across US and EU regions, the LLM Gateway gained a json-repair post-processing step, and PII redaction can now return redacted and unredacted transcripts in one request.
Help Scout keeps adding channels — now a portal customers sign into
Two customer-facing surfaces landed in a week: two-way SMS through a customer's own Twilio number, and a Customer Portal where a company's contacts sign in to see support history raised across their organization. Underneath, the SLA system built out in May and June now drives workflows, views, and reporting. Per-inbox office hours, away auto-reassignment, and availability status on web and mobile fill in the operational layer.

The supporting releases are all steps up the stack from raw transcription: an LLM gateway with output repair, speaker labels precise enough for agent turn-taking, and redaction that no longer forces a second call. The Voice Agent API is where they converge — AssemblyAI is pricing an outcome per hour rather than an API per minute, and owning the models underneath is what makes that pricing defensible.
Expect the agent pipeline to gain configuration depth — interruption handling, turn detection, or telephony ingress — since a single all-in rate only holds up if the pipeline handles real call conditions. The feed also republishes launches a day apart, so entry counts here run ahead of actual releases.

The product is widening from an agent-side inbox into the places customers actually wait — SMS, WhatsApp, and now a signed-in portal with company-level visibility. Portal access sitting on Plus and Pro puts the newest surfaces on the paid tiers rather than across the board.
Expect the portal to pick up what adjacent surfaces already have — SLA status, more self-serve actions — and the channel list to keep widening rather than any one channel getting deeper.
