## What the models said for it

- "Choose Notion if you are a startup of fewer than 50 people looking for a highly visual, collaborative workspace to build a company wiki." (Gemini 3.5 Flash, Knowledge base)
- "the strongest default choice is usually Notion if you want a flexible internal knowledge base, because it has a free plan" (Perplexity Sonar, Knowledge base)
- "For an internal team wiki, Notion (SMB flexibility) or Confluence (engineering/Atlassian) are the safe defaults" (DeepSeek V4 Flash, Knowledge base)
- "1. Notion (Free Personal Plan) ... Zero cost & easy setup | Notion (free tier) or Docsio" (Kimi K2, Knowledge base)

## And against it

- "If you use a PM tool as your primary CRM, you will end up drowning in manual data entry" (Gemini 3.5 Flash, CRM)
- "Notion is highly popular, but its greatest strength—unlimited flexibility—is also its fatal flaw for team knowledge.... Otherwise, avoid it." (Gemini 3.5 Flash, Knowledge base)
- "tools like Notion are more often positioned as flexible internal starting points rather than the strongest dedicated KB platform" (Perplexity Sonar, Knowledge base)
- "Notion or ClickUp, though they're usually less ideal than Zendesk/Confluence for a mature B2B support operation" (GPT-5.4 mini, Knowledge base)
