Notion is building the place where other companies' agents come to work
The 3.5 and 3.6 releases turned Notion into a developer platform: Workers run custom code on Notion's infrastructure, a CLI and Markdown API exist for coding agents, and External Agents bring Claude and Cursor onto a shared board where a team can assign and watch them. Custom Agents have accumulated the surrounding machinery in the weeks since — five more MCP connections, calendar tools, Outlook mail, Microsoft file read and write, audit-log coverage, and a people directory. The most recent entries are smaller and mostly about wiring: sharing context from the Share menu, sharing Workers across a team, and surfacing Worker usage in the credits dashboard before the free beta ends.
OpenPhone turns Sona into a deployable front-line AI agent with transfers and per-scenario instructions.
OpenPhone is hardening Sona, its AI phone agent, into something businesses can actually put in front of customers. Sona can now route calls to the right teammate when a human is needed, and admins can give it custom instructions per scenario (lead qualification, cancellations, booking) with templates to start from. Around it, the call flow builder keeps maturing: multiple routing setups with quick switching, in-place inbox switching during flow construction, and a Go-to Step primitive for cleaner branches.

Notion is positioning itself as the orchestration layer rather than another agent vendor, which is a different bet than most of its competitors are making. The supporting work is consistent with that: Workers to run the code, a credits dashboard to price it, an audit log to govern it, and sharing so one person's Worker becomes a team asset. The recent shift from platform launches to permissions, sharing and billing surfaces is what a product does after the capability lands and adoption becomes the constraint.
Workers move onto paid credits on August 11, so the near-term work should keep clustering around usage visibility and cost controls. The trigger surface is the other thread to watch — meeting notes became an agent trigger this window, and the same pattern applied to other Notion events is the obvious next step.

The core bet is an AI-handles-first-contact, humans-handle-edge-cases pattern. Each Sona release is closing a deployment-blocker (instructions, transfers, free trial), while the call-flow tooling underneath is getting more flexible so AI and human routing can coexist in one config. Plan-tier expansion (call hold on Starter) suggests OpenPhone is also chasing volume in the lower segment.
Expect Sona to gain CRM-aware context (caller history, deal state) and outbound use cases — proactive callbacks, scheduled follow-ups. Pricing for Sona usage is likely to evolve from a flat add-on toward usage- or outcome-based once volume appears.
