How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Hebbia (Per Usage) — Hebbia bills purely on usage. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- Microsoft 365 (Per Seat) — Microsoft 365 bills on a fixed plan from $8.4/mo, so the listed price is what you pay regardless of volume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
Enterprise AI knowledge search platform — Matrix product searches across an organization's documents, emails, chats, and CRM records to answer questions. Enterprise-only, all pricing custom-quoted. Typical deals reported $100K-2M+/year. Popular with hedge funds, law firms, and consulting firms that need to reason across large private document corpora.
Microsoft's productivity suite combining Office apps (Word, Excel, PowerPoint, Outlook) with Teams collaboration, OneDrive storage, and SharePoint. Four business plans: Apps for Business ($10/user), Business Basic ($7/user), Business Standard ($14), and Business Premium ($22, unchanged). List prices increased July 1, 2026 (Basic +16%, Standard +12%, Apps +21%). Copilot Chat now bundled into all business tiers — buyers pay for AI they didn't opt into. The dominant enterprise productivity platform, deeply integrated into Windows environments.
