Frequently asked questions
Why look for Notion AI alternatives?
Notion AI only works inside your Notion workspace, adds $10/month on top of Notion itself, and doesn't connect to data outside Notion. Most teams have knowledge scattered across many tools.
Which alternative connects to all my data sources?
Definable Knowledge Bases ingests from Notion, Google Drive, Confluence, GitHub, Postgres, MySQL, BigQuery, Snowflake, URLs, PDFs, and more — with citations on every answer.
Are my documents used to train AI models?
Definable contractually never trains on customer data on any plan. Other providers vary — check their data use policies.
