# Notion

Notion is the all-in-one docs, wiki, and project workspace a lot of teams keep their institutional knowledge in, which is exactly why it turns up in Cole's coverage as a source rather than a destination. Building a Slack personal assistant, the knowledge-base step is a three-way pick: "for your knowledge base you can use Confluence Google drive or notion" ([0:03:13](../../sources/this-slack-ai-personal-assistant-is-better-than-a-real-person.md)). Point the platform at the workspace, it ingests the pages, and the assistant answers from them.

That one line carries the useful lesson. For a classic [RAG](../../concepts/rag.md) FAQ assistant, the connector is a checkbox on a mature platform, not a project. Cole's argument in that video is explicitly [buy over build](../../concepts/buy-vs-build.md): even a technical builder should lean on something robust for a well-solved use case, because wiring up ingestion, sync, permissions, and tool calling reliably is real work that produces no differentiation. Notion, [Confluence](./confluence.md), and [Google Drive](./google-drive.md) are interchangeable at the interface level precisely because the assistant only cares about text with a source attached.

What makes Notion a good [knowledge base](../../concepts/knowledge-bases.md) for an agent is the same thing that makes it good for humans: the content is already written as prose in discrete, titled pages, so [chunking](../../concepts/chunking.md) it does not require heroics. The pages are also messy in a specific way, since Notion mixes prose with databases and tables, which is where the [structured versus unstructured](../../concepts/structured-vs-unstructured-data.md) question bites. Tabular content forced through vector search retrieves badly and is better kept queryable. The other durable trap is freshness: docs change constantly, and most vector stores insert rather than upsert, so re-syncing an edited page without [deleting its old chunks first](../../concepts/delete-before-insert-reingestion.md) leaves stale answers in circulation forever.

For personal knowledge rather than team knowledge, Cole's own stack goes local: plain markdown in [Obsidian](./obsidian.md) that an agent reads and writes directly, no connector in between. Notion is the hosted, collaborative end of the same spectrum, and it is what you point at when the knowledge lives with a team instead of on your machine.

## Realizes

- [Knowledge Bases](../../concepts/knowledge-bases.md) - Curated bodies of knowledge an agent can retrieve from, distinct from raw model weights, that ground responses in trusted source material.

## Contrasts with

- [Obsidian](./obsidian.md) - Local, markdown-based, single-user knowledge storage an agent edits directly, versus Notion's hosted collaborative workspace reached through a connector.

## Works with

- [Confluence](./confluence.md) - Interchangeable knowledge-base source in the same integration picker; Atlassian's team documentation wiki.
- [Google Drive](./google-drive.md) - The third supported source, whose file outputs feed the same ingestion pipeline.
- [Slack](./slack.md) - The chat surface the assistant grounded in these docs actually lives in.
