Some weeks you blink and a lot has shipped. Belle joined the team and builds AI voice and RCS agents from plain English, so you can stop wiring flows by hand. Webchat is a real channel now. Outbound AI calls and messages quietly check themselves for TCPA compliance. Fax finally admits when it fails. And those are just the highlights. Plenty more polish underneath that we didn't bother listing. You'll feel it.
Meet Belle - natural language builder for AI agents. You can now build AI voice and RCS agents directly through natural language. Describe what you want the agent to do in plain English and Belle handles the setup, replacing the need to wire flows together by hand.
Webchat as a channel. You can now add Webchat as a channel powered by Clerk AI, bringing the same AI agent experience to your website visitors that you already deliver over voice and messaging. Reach out to sales@clerk.ai to enable it for your team.
Self-serve Google RCS tester agents. Teams can now create and manage Google RCS tester agents directly in Clerk AI, without admin assistance. Product and messaging teams can spin up tester agents on their own to validate RCS experiences before going live.
Smoother upgrade path from Clerk AI to Startup. Free-tier teams that come in through Clerk AI now have a streamlined upgrade flow to the paid Startup plan, removing friction when teams are ready to scale up.
New HTTP Request (v2) tool in AI Workflows. The new JSON Request v2 tool returns the HTTP status code alongside the response body and lets you format or transform the payload using a template. Downstream workflow steps get cleaner, more predictable inputs, and branching on status codes is now straightforward.
More efficient contact search and count queuing. Contact search and contact count requests are now queued more efficiently, reducing overload during rapid searching and keeping the app responsive even when many requests come through in quick succession.
Real-time unread counts in the inbox. Unread badges now update more efficiently in real time, so counts stay current without relying on extra background refreshes.
Errors column in campaign analytics. Campaign analytics now include a dedicated Errors column, making it immediately obvious which messages were blocked by compliance checks or otherwise failed to send.
Clearer error drill-downs on campaign details. Campaign details now include more detailed error breakdowns so teams can quickly understand why individual messages failed and take action.
Polished campaign analytics formatting. Campaign analytics received a small usability pass, including cleaner date and phone-number formatting throughout.
More reliable real-time updates in compact inbox view. The compact inbox view now receives new messages more reliably in real time.
Improved loading for inboxes still being provisioned. Inboxes that are still being hosted or provisioned now have clearer loading behavior, providing better feedback while setup completes.
Calls with missing pipeline assignments now fail correctly. Calls that fail because of missing or misconfigured pipeline assignments are now marked as failed instead of being left stuck in progress, making configuration issues easier to identify and resolve.
Faster contact lookup failures under heavy load. Contact lookups now fail fast when the system is under heavy load instead of hanging for a long time, improving recovery during traffic spikes.
Failed fax delivery now shows correct status. Fax conversations now show a failed status when delivery does not go through, replacing earlier behavior where failures could be unclear.

Identity verification for 10DLC registration New customers will now be prompted to complete a quick identity verification step when registering for 10DLC. This is a one-time step per organization - once verified, all team members under that org are good to go.
Call forwarding You can now forward calls to another number directly from your workflow. A new Voice tab in your settings gives you control over call recording and forwarding options.
Merge calls Agents can now merge two active calls together mid-conversation - useful for bringing in a supervisor or connecting two parties.
Play media during calls A new "Play media" step lets you play hold music or audio clips during a call, with controls for when to resume the conversation.
New voice model: Gemini 3.1 Flash Lite Gemini 3.1 Flash Lite preview is now available as a voice model option when configuring your AI agents.
RCS carousels You can now build and send rich carousel messages over RCS directly from your workflows - great for product showcases or multi-option menus.
Replay past workflow executions Need to debug a workflow run? You can now replay any past execution directly from the execution details panel to see exactly what happened.
New AI model options Added GPT-5.4 and Grok 4-1-fast (xAI) as model choices for your AI agents.
More conversation filters The Conversations API now supports filtering by unread status, whether an assistant is enabled, and updated-before/after timestamps - making it easier to sync and triage at scale.
Improvements
Scheduled agents run on time. Previously, scheduled agents could fire within a 5-minute window. They now run at the exact scheduled time, and you can point them at different workflows as needed.
More control over agent context. Two new options: limit how far back in conversation history your agent looks, and choose whether call transcripts are included.
More reliable AI responses. Reduced cases where AI steps return responses in an unexpected format. All providers now enforce consistent structured output.
Faster inbox updates. Inbox should feel noticeably more responsive - conversation assignments and new messages now update in real time more reliably.
Simpler workflow variables. Passing data between steps in the workflow builder is now more streamlined.
Fixes
Fixed a bug where loading older messages in a thread could cause the view to jump or overlap.
Fixed an issue where some RCS carousels were not sending correctly.
Removed a file type check that was incorrectly rejecting CSV uploads.

Background & Thinking Noises for AI Agents
You can now configure background and thinking noises for AI agents directly in Inbox Voice Settings, including independent volume controls. Background noise plays continuously during a call, while thinking noise plays when the agent is generating a response.
Speak Tool (Deterministic Audio in Agent Flows)
The new Speak Tool allows you to play deterministic text or audio at any point in an agent flow. This ensures specific messages are delivered exactly as written when precision and consistency are required.
Voice Previews in Inbox Settings

New
You can now choose how you want to roll out your agents with three deployment options:
Deploy for all users pushes your agent to 100% of traffic immediately—perfect for when you're ready to go fully live.
Staged Deployment lets you deploy to a specific phone number, so your agent only activates for calls or texts from that inbound number. Great for controlled testing with a specific audience.
Canary Deployment gives you a traffic percentage slider to gradually roll out your agent. Start at 10%, monitor performance, then scale up as you gain confidence.

We’ve added an extra layer of protection to your campaign workflow to help prevent accidental sends and ensure carrier compliance.
Now, when you finish setting up your campaign, selecting your list, writing your message, and choosing a send time, you’ll encounter a final confirmation after clicking "Send Now."
