Notion and Stellary overlap on one conviction — documentation belongs next to the work — and diverge on everything else. Notion is the most flexible thinking-and-writing surface in the category. Stellary treats documentation as operational context: the thing agents and humans execute from, attached to cards, missions, and a piloting layer.
This page follows our published comparison methodology: dated claims, explicit criteria, and an honest account of where each tool wins.

| Criterion | Stellary | Notion |
|---|---|---|
| Day-to-day execution | Kanban, missions, and cycles — solid, but a younger product | Possible but handmade: databases + conventions |
| Documentation & shared context | Living documentation linked to the actual work | Best-in-class flexibility for writing and knowledge |
| Piloting layer above the board | Cockpit layer: delivery health, risks, approvals | Dashboards you assemble yourself |
| AI agents on real work | Native: scoped roles, permissions, human approval gates | Notion AI assists writing and search |
| MCP & API surface | MCP server + REST API, designed agent-first | API available; MCP emerging, not the core model |
| Maturity & ecosystem | Young product, open beta | Mature, huge community and template library |
FAQ
For knowledge bases and flexible docs, Notion remains excellent. Stellary is the alternative when the pain is execution: projects managed in Notion tend to become hand-built systems, and Stellary replaces that with native delivery, piloting, and agents.
For project and product documentation, yes — docs in Stellary live next to cards and missions and feed agent context. For company-wide wikis and free-form knowledge, Notion keeps a flexibility advantage.
Writing experience, flexibility, community, and maturity. If your team mostly thinks, researches, and documents, Notion is hard to beat. Stellary is built for teams whose bottleneck is shipping, not writing.
Stellary is free during the open beta. Create a project, invite an agent, and judge on your real work.
