The short version

  • Only Gamma has a free tier, so it costs nothing to try first.
  • Each has a real cost: Gamma free plan limited to 400 non-renewable credits, requiring paid plan quickly; Microsoft 365 business plans are capped at 300 seats, so an organisation that grows past that must move to Enterprise plans, which changes both the price per user and the feature mix at the moment it can least afford a migration project.
  • They diverge on capability: Gamma covers AI Slide Generation, Microsoft 365 covers Office applications.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Gamma

  • Free plan limited to 400 non-renewable credits, requiring paid plan quickly
  • Credit rollover capped at 2x monthly allocation, forcing month-to-month spending
  • Refund window limited to 3 days with usage thresholds restricting claims
  • Per-seat pricing on team plans increases costs for large organizations
  • Studio Mode limited to Ultra plan, restricting advanced editing to highest tier

Microsoft 365

  • Business plans are capped at 300 seats, so an organisation that grows past that must move to Enterprise plans, which changes both the price per user and the feature mix at the moment it can least afford a migration project.
  • The compliance capabilities most organisations eventually need, including retention, data loss prevention, advanced eDiscovery and insider risk, sit at the top tier or in add-ons, so the real cost surfaces after an audit or a customer questionnaire rather than at purchase.
  • Annual term subscriptions commit you for the year and month-to-month terms cost measurably more per seat, so the flexibility to reduce seats during a quiet period is bought at a permanently higher rate.
  • Entra ID becomes the identity for everything else the organisation uses, which is the hardest kind of lock-in to put a number on, because leaving means re-federating every connected application rather than simply replacing a word processor.
  • The licensing model is complicated enough that most organisations are either over-licensed or quietly non-compliant, and reconciling it usually requires a partner or a specialist, which is a recurring cost that never appears in the advertised per-user figure.

Answered from the vendors’ own pages

Gamma: How do Gamma AI credits work?

Each plan includes a monthly AI credit allowance. Free users receive 400 one-time credits. Plus plan includes 1,000 monthly credits, Pro includes 4,000 monthly credits, and Ultra includes 20,000 monthly credits. Unused credits roll over up to 2x the monthly allowance.

Source
Microsoft 365: What is the difference between Microsoft 365 and Office?

Office was a one-off licence for a specific version. Microsoft 365 is a subscription covering the applications and the hosted services together, and when payment stops the applications drop to a reduced state rather than continuing as they were.

Gamma: What is included in the Free plan?

The Free plan includes 400 AI credits (one-time), up to 10 cards per prompt, basic AI, Gamma branding on output, and 7-day change history.

Source
Microsoft 365: Is Teams included?

Not automatically for newer customers. Microsoft unbundled Teams and now sells it alongside the suite, so check what a given quotation actually covers.

Gamma: What payment and refund options does Gamma offer?

Gamma offers a 3-day refund window for monthly plans if you have used less than 10-20 percent of your monthly credits depending on the plan.

Source
Microsoft 365: What happens to our files if we stop paying?

The documents remain yours and can be downloaded, but access to hosted mailboxes and sites ends after a retention window, so leaving requires a planned export rather than a cancellation.

Gamma: How much do Team and Business plans cost?

Team plans cost $20 per seat per month with a minimum of 2 seats, including 6,000 AI credits per seat. Business plans cost $40 per seat per month with a minimum of 10 seats, including 10,000 AI credits per seat.

Source
Microsoft 365: Is Copilot part of the subscription?

No. It is a per-user add-on on top of the base licence, generally with its own term commitment, and it is priced per seat regardless of how much any individual uses it.
