What 15 people really pay for a team wiki
Confluence and Notion charge for every member who can edit. Arcane Trinity charges only for the pages and files you store.
Competitor prices are list prices in US dollars on annual billing, as published on their websites in October 2026, before taxes. Prices in your country and currency may differ.
Questions about Trinity
Can I import from another wiki?
Yes. Import a .zip export from Confluence or Notion, or HTML, Markdown, text, Evernote and CSV files. CSV files become databases.
Does Ask AI see private pages?
Only the pages the person asking can open, so it never answers from someone else's private pages. Arcane AI doesn't train on your pages, and it's paid for per use.
Can I share a page publicly?
Yes. Publish a page to the web and anyone with the link can read it, without an account. The pages under it are published too, and you choose whether search engines can list it.
Can I control who edits a space?
Yes. Each member of a space is an owner, editor, commenter or viewer, and a space is either readable by your whole organization or hidden from everyone you don't add.
