Notion
FreemiumDocs, wikis and databases in one workspace, with an API and MCP server for agents to read and write.
What it is
Notion is a workspace where pages, wikis and relational databases share one editor. A database view can be a table, board, calendar or gallery over the same rows; pages nest without limit; templates and buttons automate the boring parts. The current product adds Notion AI (search and Q&A across the workspace, meeting notes), a public API that covers pages, blocks and database queries, and an MCP server so agents can search, read and create pages without custom code.
There is a free plan for individuals and per-seat paid plans for teams; AI is bundled or added depending on the plan. For a small company Notion tends to become the "everything that is not code" store: onboarding docs, meeting notes, the CRM before you need a CRM, the content calendar before you need a content tool.
Where it fits in the AI OS
Work OS, the shared memory of the team. The value for an agent-operated company is that agents can read the same handbook humans read and write status pages humans actually open. It also overlaps with the Personal AI OS as a knowledge base, where the choice is between a hosted workspace (Notion) and local Markdown (Obsidian).
Insider notes
membersHow Serge's stack uses it
The project's own documents live as Markdown in the repository rather than in Notion: the spec, the decision log, research and the ideas cards are all files that the agents read directly.

Setup in 5 minutes
- Create a workspace; make one page "Handbook" and one database "Decisions" with columns Date, Question, Decision, Owner.
- Under Settings → Connections, create an internal integration and share the database with it.
- Query it:
POST https://api.notion.com/v1/databases/<id>/querywith the integration token andNotion-Versionheader. - Add the Notion MCP server to Claude Code; ask it to "append today's decision to the Decisions database".
- Set the Handbook page as the team's default landing page.
Alternatives
- Obsidian — local Markdown, plugins, no per-seat cost; weaker for team editing.
- Coda — similar docs-plus-tables model with stronger formulas.
- Google Docs / Drive — everyone has it; no database layer.
- A Git repository of Markdown — what this project does; perfect for agents, less friendly for non-technical teammates.
