Atlas vs Confluence
Confluence is the default corporate wiki: mature spaces, page trees, permissions and a large app marketplace. The trade-off is cost structure. Every person who needs to read a page needs a seat, at roughly $13 per user per month on Standard, and AI answers arrive as a further paid add-on. For a 50-person company that is around $7,800 a year before AI.
Atlas covers the same core writing and organising surface — nested spaces, drag-and-drop page trees, tables, code blocks, callouts, comments, mentions, version history and granular space permissions — with no seat charge at all. AI search is native rather than an upsell: every page and uploaded PDF is vector-indexed as you write, and answers come back with citations to the source page.
Atlas vs Notion
Notion is excellent for flexible databases and personal organisation, and its free tier is generous for individuals but limited for teams. Where Notion optimises for the building-blocks model, Atlas optimises for the documentation model: a permissioned knowledge base that an AI assistant can search reliably. If your goal is trustworthy, cited answers about how your company works, a wiki that indexes for retrieval from day one is a better fit than a general workspace.
Atlas vs Glean
Glean is enterprise search: it crawls your SaaS tools and answers questions across them, typically around $50 per user per month on an annual contract with a platform minimum. It is not a wiki, so most Glean customers also pay for Confluence or Notion underneath — roughly $63 per user per month combined.
Atlas collapses those two line items into one product. Your documentation lives in Atlas, and the same content is retrieved through RAG with permission-aware filtering, so nobody sees an answer sourced from a space they cannot open. Where you need external systems, Atlas connects through MCP in both directions — reading and writing content — instead of a fixed connector catalogue.
Why usage-based AI pricing is cheaper
Per-seat AI pricing charges for every employee whether or not they ask questions. In practice a small share of a team drives most AI usage. Atlas bills the actual tokens consumed at $1 per credit, and one credit covers roughly 300–700 typical answers, so a busy 50-person team frequently lands under $30 a month in AI spend. Each organisation can also set a hard monthly cap so spend never surprises you.
Frequently asked questions
How much does Confluence cost per user?
Atlassian lists Confluence Standard at roughly $13 per user per month on monthly billing, before add-ons. Confluence AI (Rovo) and Premium tiers cost more again, and every seat is billed whether the person writes documentation or only reads it.
How much does Glean cost per user?
Glean is sold on annual enterprise contracts, commonly quoted around $50 per user per month with platform minimums. It is an AI search layer, so most teams pay for Glean on top of a wiki like Confluence or Notion rather than instead of one.
How is Atlas free?
The wiki itself — pages, spaces, unlimited members, real-time collaboration, permissions, MCP access — costs $0 with no per-seat charge. Only AI work is metered at $1 per AI credit, and one credit covers roughly 300–700 typical answers.
Is Atlas a real Confluence alternative for large teams?
Yes. Atlas supports nested spaces, page trees, granular space and page permissions, version history, comments, mentions, notifications, tables, code blocks and file uploads — with strict per-organization data isolation.
Can I keep Confluence and add Atlas?
Many teams start by moving one space over. Because Atlas has no seat cost you can run it alongside an existing wiki during migration and only pay for AI usage.
Does Atlas replace Glean-style enterprise search?
For your team's documentation, yes: Atlas vector-indexes every page and PDF and answers questions with citations, respecting the same permissions as the wiki. Glean additionally crawls dozens of third-party SaaS tools; Atlas connects through MCP instead.
Move one space and compare for yourself
There is no seat cost, so you can run Atlas alongside your current wiki while you migrate. See the full pricing breakdown or read how our AI knowledge base works.
