Granite Business
The knowledge base your team actually keeps up to date.
A company wiki that feels like a fast notes app. Write in Markdown, edit together live, organize vaults by team, and control every door with SSO, roles, and audit logs, for $15 per seat.
In short
Granite Business is knowledge base software for companies: shared Markdown vaults with live co-editing, comments and mentions, owner, admin, member, and guest roles, groups, folder-level access, single sign-on (SAML 2.0, OpenID Connect), SCIM, security policies, an audit log, 24 months of version history, and a workspace-wide AI knowledge base for Claude, ChatGPT, and Cursor. It costs $15 per seat per month; guests are free.
01 · Collaboration
Real-time co-editing that survives bad Wi-Fi.
See who's in a note, where they're typing, and follow them through a document. Keep writing offline; everything merges when you reconnect.
- Cursors and presence with names and follow mode.
- Comments on any text, with mentions and notifications.
- Version history on every change, restorable by anyone with access.
02 · Structure
Vaults for teams. Folders for secrets.
Give every team a vault, share across teams with groups, and lock down the folders only a few people should see. Invite contractors and clients as free guests who can view and comment.
- Roles: owner, admin, member, guest.
- Folder grants: reader, commenter, editor, admin.
- Domain capture and invitations by email or link.
03 · Administration
An admin console IT will like.
Connect your identity provider, require two-step verification, cap session lengths, choose which apps and AI tools are allowed, and review everything in the audit log.
- SSO with Okta, Microsoft Entra ID, Google Workspace, and any SAML or OIDC provider.
- SCIM to add and remove people automatically.
- Audit log with CSV and JSON export and streaming.
04 · AI
Your whole company's AI, reading from one page.
Workspace-wide AI knowledge base: everyone's AI assistant answers from the same, current notes, with citations and each person's permissions.

FAQ
Business questions.
What is the best knowledge base software for a small company?
Small companies need a knowledge base that people enjoy writing in, that's easy to search, and that doesn't require a security team to run. Granite combines a fast Markdown editor and live co-editing with SSO, SCIM, permissions, and audit logs, for $15 per seat with free guests, and makes the same knowledge available to your team's AI tools.
Can Granite replace our internal wiki?
Yes. Teams use Granite for handbooks, policies, onboarding, runbooks, product specs, and meeting notes. Import from Notion or Obsidian, organize by vault and folder, and link everything with wikilinks and backlinks.
Who counts as a seat?
Every workspace member above the guest role. Guests can view and comment for free; editors need a seat. Business needs at least 2 seats.
Is there a free trial?
Yes: 14 days of Business, free, with no card required.
Does Granite support SAML SSO and SCIM?
Yes. Business workspaces support SAML 2.0 and OpenID Connect single sign-on with providers such as Okta, Microsoft Entra ID, and Google Workspace, plus SCIM provisioning to add and remove members automatically.
Can we self-host Granite?
Not today. Granite is a hosted service, with a key per workspace, encrypted backups, a data processing agreement, and full export, so you're never locked in.
