Pricing
No per-seat pricing.
Your agents write and your whole company reads, so we don't count either. Plans differ by storage and by the controls a company needs.

Storage
Storage counts the current version of every live document. On Free, add 50 GB for $5 a month without changing plans. Enterprise includes 5 TB, with more by agreement.
Paid workspaces can turn on usage billing once an owner accepts the rate and a monthly limit. Sustained overages are prorated after a grace period. At the limit, existing documents stay readable.
Sharing with your whole workspace
New pages are Restricted. Add the whole workspace to share a page with everyone in it. Readers sign in before the page opens, so a forwarded link stops at the login page.
Team uses Google sign-in. Business adds Microsoft Entra and Okta.
Questions
Can I start for free?
Yes. The Free plan includes 1 GB of storage and supports publishing and sharing pages, documents, images, and other files. Restricted sharing is included. Paid plans add more storage, custom domains, groups, and company controls.
How do I upgrade to Team or Business?
Create a free account, then choose a plan in Settings → Billing and check out. Email us for Enterprise or if you need annual invoicing.
Do readers need an AI account?
No. Readers open the page in their browser. Choose Restricted, Password, or Anyone with the link. Restricted readers sign in as someone you added; Password readers enter the password. Reading a page never requires an AI tool.
Which AI tools can I use?
Claude Code, Codex, Cursor, Claude Desktop, and other clients that support remote MCP servers. MCP is the connection that lets your AI read, publish, and update content in Fermium. The getting-started guide walks you through connecting your tool.
Can I lock a document to my company?
Yes. Every plan supports Restricted pages with Google sign-in, shared with members of your workspace. Business and Enterprise also support Microsoft Entra and Okta through OpenID Connect, along with more access and policy controls. Readers need access even when a link is forwarded.
Do links expire?
Links expire after 30 days unless you keep them. Keep any link you want to stay live.
What happens when the link is updated?
The URL stays the same. Ask your AI to update the existing document, or edit it in the app. Readers see the latest version at the original link, and you can restore an earlier version while it is available in your plan's history.
How do I make a page with Fermium?
Connect a compatible AI tool to Fermium, give it your notes or source material, and ask it to create and publish an HTML page. Your AI creates the content and design; Fermium hosts the result and gives you a link. You can also upload existing files and edit documents in the web app.
Can our team keep its knowledge together?
Yes. Keep documents in shared folders and publish a folder as a knowledge site so people have a clear place to start reading. Agents hold instructions, reusable workflows, and memory that your AI can use across sessions.
Start free. Upgrade when you're ready.
Choose Team or Business in Settings → Billing after you sign up. Email us for Enterprise or annual invoicing.
