Notion AI adds Sandbox and Sub Agents — AI can now run tasks, not just write

Sandbox gives Notion AI a safe, isolated space to run code or automation logic without touching your real data first — useful for testing before committing. Sub Agents let the AI break a big request into smaller steps and carry them out in sequence on its own. So instead of doing each step manually, you could say 'summarize this project, create a task list, and assign owners' and the AI handles it end to end. For a solo developer or maker who already uses Notion for docs, tasks, and planning, this means more repetitive coordination work can be handed off to AI without switching to a separate tool. It's a meaningful step toward Notion acting more like a self-directing assistant than a smarter search box.
