What is Notion?

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.

What is Signal?

Closing the UX gap while pushing the crypto frontier.

Signal is running two parallel programs: a cryptographic agenda (post-quantum ratchet, defenses against Microsoft Recall) and a long-overdue UX parity push (secure backups, polls, pinned messages, group labels). The product has matured past pure privacy infrastructure and now ships features mainstream users have asked for for years. Each direction reinforces the brand: still the most paranoid messenger, but no longer the one that loses your chat history when your phone breaks.

Notion is building the place where other companies' agents come to work

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

Closing the UX gap while pushing the crypto frontier.

◆ Current state

Signal is running two parallel programs: a cryptographic agenda (post-quantum ratchet, defenses against Microsoft Recall) and a long-overdue UX parity push (secure backups, polls, pinned messages, group labels). The product has matured past pure privacy infrastructure and now ships features mainstream users have asked for for years. Each direction reinforces the brand: still the most paranoid messenger, but no longer the one that loses your chat history when your phone breaks.

◆ Where it's heading

The cadence over the last 12 months shows a deliberate alternation between cryptographic milestones and feature catch-up. Backups, polls, pinned messages, and group labels are the kind of work Signal historically deferred; shipping them in quick succession signals a strategic decision to remove every easy reason a user might leave for WhatsApp or iMessage. Meanwhile SPQR positions the protocol for the next decade of cryptographic threat models, keeping the security story intact while the UX story finally catches up.

◆ Prediction

Secure backups will graduate from Android beta to iOS and Desktop within the next two releases. Expect another round of feature-parity work — message editing depth, richer media handling, or reactions — before the next protocol-level cryptographic move.
