All three give you a place to put your team's knowledge. The difference is who does the writing. With Notion and Confluence, your team writes and maintains every page. With Sofie Wiki, the AI writes and updates the pages for you from chat, and your team reads and edits when they want to.
If your team keeps losing knowledge in stale docs, the issue is not the tool. It is that no one has time to keep the docs current. Sofie Wiki fixes that by doing the writing for you.
Notion and Confluence tie you to the AI they bundled. Notion AI is Notion AI; Atlassian Intelligence is Atlassian Intelligence. Sofie Wiki lets you pick the provider: ChatGPT, Google Gemini, Anthropic, Mistral, or any OpenAI-compatible endpoint you already have. Prompts run through your account, under your provider's terms, so you are not forced into a second AI subscription just to keep your wiki updated.
