The short version

  • Only Kami has a free tier, so it costs nothing to try first.
  • Each has a real cost: Kami the free Basic plan exposes only about 10 of the 40 or more tools; 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: Kami covers PDF annotation, Microsoft 365 covers Office applications.
  • Prices and features above were last checked on 30 August 2026.

  • A household that needs installed Office applications on several machines rather than browser-only editing.not Kami

Where each one falls short

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

Kami

  • The free Basic plan exposes only about 10 of the 40 or more tools
  • Google Classroom, Schoology, Canvas and Microsoft Teams integrations require the Teacher plan at $149 per year
  • School and district licensing including domain wide deployment is custom priced and requires a quote
  • Non education users pay separate Workplace plans at $85 or $220 per year rather than the education rate
  • A dedicated account manager is only available on the School or District plan

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

Kami: Does Kami offer a free plan and what does it include?

Yes, Kami's free Basic plan includes 10+ essential tools, unlimited collaborators, Google Drive/OneDrive integration, and 1,000+ templates. Full feature access requires Pro or higher tiers.

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.

Kami: What is the cheapest paid plan for Kami and what does it cost?

Pro plan is $12/month ($85/year when billed annually) and includes all 40+ tools, unlimited pages, and priority support for workplace users.

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.

Kami: Are there Kami plans designed specifically for educators?

Yes, the Teacher plan costs $149/year and includes all 40+ tools, full LMS integrations (Google Classroom, Schoology, Canvas, Teams), free onboarding, and priority support with a 30-day free trial.

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.

Kami: How much do Kami School or District plans cost?

School and District plans do not publish pricing and require contacting Kami for custom quotes. These plans include domain-wide deployment, dedicated account managers, and full LMS integrations.

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.
