The short version

  • Only Circleback has a free tier, so it costs nothing to try first.
  • Each has a real cost: Circleback the free plan keeps 30 days of history, so it serves immediate follow-up and fails as a record, and the tier that made it look free has to be paid for the first time anyone needs a conversation from last quarter.; 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: Circleback covers Calendar-driven recording, Microsoft 365 covers Office applications.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Circleback

  • Consultancies that need an accurate record of what a client asked for and when they asked for it.not Microsoft 365
  • Distributed teams where people who missed a call need the substance rather than an hour of recording to sit through.not Microsoft 365
  • Managers and founders running many short calls where the action items are the only output that matters.not Microsoft 365

  • A company standardising on single sign-on, where Entra ID becomes the account other services authenticate against.not Circleback
  • Regulated work that needs retention, legal hold and eDiscovery across mail and documents, provided the tier that includes them is actually bought.not Circleback
  • A household that needs installed Office applications on several machines rather than browser-only editing.not Circleback

Where each one falls short

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

Circleback

  • The free plan keeps 30 days of history, so it serves immediate follow-up and fails as a record, and the tier that made it look free has to be paid for the first time anyone needs a conversation from last quarter.
  • Custom retention and admin roles are on the Business tier and single sign-on and HIPAA on Enterprise, which is the familiar pattern of an organisation discovering the real price only after individuals have adopted the tool and filled it with client conversations.
  • Pricing is per user and a note taker spreads to everyone who attends meetings rather than staying with one team, so the seat count tracks headcount, and free viewer accounts only arrive at the Business tier.
  • Transcription errors persist on accents, crosstalk and domain jargon, and because the output becomes the official record people stop checking it against what was actually said, so a mistranscribed commitment can outlive everyone's memory of the meeting.
  • Recording consent rules differ by jurisdiction and some require every participant's agreement, and the obligation rests with you rather than the vendor, so a bot joining calls automatically from a calendar can create a compliance problem nobody consciously chose.

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

Circleback: What does the free plan include?

Unlimited meetings, notes and action items, speaker-labelled transcripts, in-person recording, and Slack and Linear integrations, with history limited to 30 days. Longer history and the wider integrations are the paid line.

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.

Circleback: How accurate are the notes?

Good on clear audio and worse with heavy accents, crosstalk and specialist jargon. Because the notes become the record, spot-check anything consequential rather than assuming somebody else will.

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.

Circleback: Do we need everyone's consent to record?

It depends on jurisdiction, and some require all-party consent. The obligation sits with the meeting organiser, not with the vendor, so set a policy before enabling automatic joining.

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.

Circleback: Can we control how long recordings are kept?

Custom retention is a Business-tier feature. On the lower tiers you accept the defaults, which is worth knowing before client conversations start accumulating.

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.
