Notion
Notion is structured around four plans (Free, Plus, Business, Enterprise) priced per workspace member. The platform philosophy is that knowledge work shouldn't be fragmented across docs, project tools, and databases — a single flexible workspace handles all of it. Block-based editing lets pages contain rich content of any type. Databases with multiple views (table, board, calendar, gallery, timeline) replace separate project tools. AI Agents (launched September 2025), Custom Agents (Notion 3.3, February 2026), and Ask Notion query the entire workspace including connected sources like Google Drive and Slack.
Pricing in 2026: Free for individual use with unlimited pages and blocks (1,000-block team limit when collaborating). Plus at $10/user/month annual ($12 monthly) with unlimited file uploads, 30-day version history, 100 guests. Business at $20/user/month annual ($24 monthly) — the first tier with full Notion AI access, private teamspaces, SAML SSO, 90-day version history, 250 guests. Enterprise custom pricing with SCIM, audit logs, unlimited page history, advanced security controls, dedicated CSM. May 2025 pricing restructure eliminated standalone AI add-on; full AI now requires Business tier minimum.
