Notion Introduces Plan Mode for Safer Agent Execution.

Notion has launched Plan Mode, a new safety layer for its Custom Agents that lets users preview and approve an agent's proposed actions before any changes are made to their workspace.

The feature introduces a three-step workflow: plan, approve, execute. When activated, Notion agents display their reasoning and intended steps inside a read-only sandbox. Users can review exactly what the agent plans to do, then approve or reject the proposed actions before they touch any live data.

The announcement comes as Notion continues to roll out Custom Agents, AI teammates designed to handle entire workflows autonomously. While these agents can complete multi-step tasks like drafting reports or managing project boards, giving them free rein to edit workspaces has created friction for some teams.

Plan Mode addresses this by making agent behavior transparent. Instead of executing actions immediately, the agent first generates a preview of its work. This mirrors the review mechanisms found in enterprise software, where critical operations require human signoff before proceeding.

For teams that have adopted Custom Agents, the feature offers a middle ground between full automation and manual execution. It's particularly relevant for workflows that touch sensitive data, high-stakes projects, or cross-functional documents where unintended edits could ripple across teams.

When Plan Mode is enabled, users trigger an agent as usual. The agent analyzes the request, generates a plan, and displays it in a sandbox environment. This sandbox is read-only, meaning the agent can't modify actual workspace content during the planning phase.

Users see the proposed changes, including any edits to databases, page updates, or task assignments. If the plan looks correct, they approve it. The agent then executes the workflow. If not, they can reject the plan or refine the prompt.

The feature builds on feedback from Notion's Custom Agents beta, which included companies like Ramp and OpenAI. According to Notion's blog, beta users expressed a need for more control over agent actions, especially when scaling workflows across large teams.

Notion's move reflects a wider trend in enterprise AI tooling: balancing automation with oversight. As agents become more capable, the risk of unintended consequences grows. A misinterpreted prompt or faulty logic can result in overwritten documents, incorrect data entries, or broken workflows.

Plan Mode is one answer to that problem. It doesn't slow down agents that work well, but it prevents runaway automation when context is ambiguous or stakes are high.

Other workspace platforms have taken similar approaches. Slack workflows often include approval steps for critical actions, and project management tools like Airtable let users review automation outputs before committing changes to live bases.

For Notion, Plan Mode is part of a broader effort to make agents safe enough for production use. The company has also introduced usage controls and analytics to help admins track agent activity and set guardrails.

Plan Mode is rolling out to Notion workspaces with access to Custom Agents. The feature is available on Business and Enterprise plans, where agents are included as part of Notion's AI suite.

Users can toggle Plan Mode on or off per agent, depending on the workflow. For routine tasks like generating meeting notes or tagging documents, full automation may still make sense. For higher-risk operations, the preview step adds a layer of confidence.

Notion has not indicated whether Plan Mode will eventually become mandatory for certain agent types or remain an opt-in control. The company announced the feature on LinkedIn, framing it as a way to move from "prompt without a plan" to structured, reviewable execution.
