RAG

How do you build RAG over a Notion workspace?

Notion RAG uses the Notion API as a sync source: read pages and databases, convert blocks to text, mirror workspace permissions, and update the index as content changes. Then query the corpus with citations. Plugsky collections handle chunking, embedding and retrieval once the connector delivers clean text and metadata.

Key facts

ApproachSync pages and databases via the Notion API into collections
Content modelPages and blocks convert to text; databases map to structured metadata
FormatsUpload text derived from Notion content as TXT, MD or HTML
PermissionsMirror workspace access with collections or metadata filters and scoped keys
RetrievalKeyword, vector and hybrid search with optional reranking and citations
Data handlingPer-collection encryption at rest; API data is not used to train models
DeploymentManaged, VPC, on-prem and air-gapped options

TL;DR

  • Convert blocks to plain text; rich structure is noise to retrieval.
  • Promote database properties into metadata for filtering and citations.
  • Mirror Notion permissions or answers will cross team boundaries.
  • Sync on a schedule and remove deleted pages from the index.
  • Keep the Notion page id so every citation links back to the source.

How it works, step by step

  1. Create a Notion integration and share only the pages or databases in scope.
  2. Traverse pages and child blocks, converting them to plain text.
  3. Map database properties such as status, owner and team into metadata.
  4. Upload documents to collections with the Notion page id and URL.
  5. Mirror workspace permissions through collection boundaries or filters.
  6. Schedule incremental syncs and handle deletions explicitly.
  7. Test retrieval with real internal questions and verify citations resolve.

Turning Notion blocks into retrievable text

Notion stores content as blocks: paragraphs, headings, lists, callouts, toggles, tables and embeds. Retrieval needs text, so the connector walks the block tree and emits a representation that preserves meaning. Headings become section markers, lists stay grouped with their introducing sentence, callouts become ordinary paragraphs with their label, and code blocks are kept intact.

Tables and databases deserve special handling: flatten rows into sentences or structured records, and promote properties such as owner, status and team into metadata. Metadata is what makes filtered retrieval possible later, for example limiting a query to one team's documentation.

Permissions are the main risk

Notion workspaces contain drafts, restricted pages and team-specific material alongside shared documentation. A retrieval index that ignores those boundaries will surface content to people who cannot open the page. The integration itself limits which pages are visible, but that is not the same as mirroring the permission model for end users.

The practical approach is to sync separate workspaces, spaces or databases into separate collections and issue scoped keys per audience, or to attach a permission label to each chunk and filter on it. Whatever the mechanism, test it with negative cases: a user who cannot open a page must not retrieve its content.

Keeping the index current

Notion content changes continuously. Run incremental syncs on a schedule, track the last-edited timestamp or cursor per page, and update only what changed. Deletions are easy to miss: when a page disappears from the API response, remove the corresponding document from the collection so stale chunks do not keep answering questions.

Keep a stable identifier per page so re-syncs update in place rather than duplicating documents. Duplicates are one of the most common causes of repetitive, confused answers.

Querying and citing Notion content

Once synced, the corpus behaves like any RAG workload: keyword, vector or hybrid retrieval with optional reranking returns ranked chunks, and citations carry the source reference so users can open the Notion page. Any of 30+ models can compose the answer on the same OpenAI-compatible API, and per-collection encryption plus the no-training commitment cover the usual internal-data questions.

Frequently asked questions

Is there a Notion connector built into Plugsky?

No. You run a small connector using the Notion API to sync content into Plugsky collections, where chunking, embedding and retrieval are managed.

How should databases be ingested?

Flatten rows into text and promote properties such as owner, team and status into metadata so queries can filter on them.

How do I respect Notion permissions?

Sync audience-specific content into separate collections with scoped keys, or attach permission labels to chunks and filter on them. Verify with negative tests.

How often should syncs run?

As often as your content changes matter. Incremental syncs based on last-edited timestamps keep the cost proportional to actual changes.

Is there a free plan?

Yes. The free plan includes plugsky-micro and plugsky-lite with 2 API keys and no credit card, and a 14-day full-access trial is available.

How is pricing structured?

Self-serve plans are flat monthly with unlimited fair-use usage and no per-token charges or overage fees. See the live pricing page for current plans.
