Otter vs Fireflies vs Teams Premium AI meeting notetakers compared side by side for accuracy and price

Otter vs Fireflies vs Teams Premium is one of the most common questions we get asked by businesses trying to work out which AI meeting notetaker actually suits how they work, because all three do broadly the same job in noticeably different ways. Otter and Fireflies are standalone tools that join a call as a guest and transcribe it independently of whichever video platform is being used. Teams Premium takes a different approach entirely, building the notetaking directly into Microsoft Teams itself rather than adding a separate bot to the call.

Here is what actually separates the three once you look past the marketing.

How the Three Tools Actually Join a Call

Otter and Fireflies both work as a visiting bot that joins Zoom, Teams, Google Meet or almost any other video platform a business happens to use, which makes either a sensible choice for a business running a mix of tools across different teams. Teams Premium has no equivalent flexibility. It only works inside Microsoft Teams itself, which is a strength if the business is fully standardised on Teams and a limitation the moment anyone dials in from Zoom or Meet instead.

Transcript Accuracy and Speaker Identification

Both Otter and Fireflies have built a strong reputation for real time transcription accuracy and reasonably reliable speaker identification, particularly in calls with a small number of clearly separated voices. Teams Premium benefits from sitting directly inside the Teams audio pipeline rather than listening in as a guest, which can help with accuracy in a well configured meeting room, though it depends heavily on the room's own microphone setup performing well in the first place.

None of the three is immune to the same problem every transcription tool faces, several people speaking over each other, background noise, or a poor quality microphone all reduce accuracy regardless of which platform is doing the listening.

Summaries, Action Items and Where the Notes Actually Live

Where the three tools differ most is what happens after the call ends.

Otter produces a searchable transcript with automated summaries and highlights, and supports live collaborative notes during the call itself.
Fireflies leans more heavily into integrations, pushing summaries and action items directly into CRM systems and project management tools businesses already use.
Teams Premium keeps everything inside the Microsoft ecosystem, with recaps appearing in Teams chat and integrating naturally with OneNote and other Microsoft 365 tools.

Price and Where the Real Cost Sits

Otter and Fireflies both charge a per user monthly fee on top of whatever video conferencing tools a business already pays for, with pricing tiers that scale by feature set and usage volume. Teams Premium is licensed as an add-on to an existing Microsoft 365 subscription, so for a business already paying for Microsoft 365 it can work out cheaper in practice, provided the business is actually running everything through Teams rather than paying for a licence that only covers part of its meetings.

It is worth costing all three properly rather than assuming the cheapest headline price wins, since a tool that only works inside one platform is not much use to a business running meetings across several.

Data Privacy and Where Recordings Actually Live

This is worth checking properly before rolling any of the three out, since each stores recordings and transcripts in a different place. Otter and Fireflies both store data on their own servers, separate from whichever video platform hosted the call, which means a business needs to review each provider's own data retention and privacy policy independently. Teams Premium keeps everything inside the existing Microsoft 365 compliance and data residency settings a business has already configured, which some IT teams find considerably easier to govern than adding a third party tool into the mix.

Otter vs Fireflies vs Teams Premium: Which Should You Choose?

If a business runs meetings across a genuine mix of platforms, Otter and Fireflies both offer more flexibility than Teams Premium ever will, and the choice between the two usually comes down to whether CRM integration or collaborative note taking matters more day to day. If a business is fully standardised on Microsoft Teams and already pays for Microsoft 365, Teams Premium is often the simplest option, since it removes the need to manage a separate tool and a separate login entirely.

Whichever tool ends up being chosen, it is worth running a short trial across a handful of real meetings first, checking the transcript against what was actually said, rather than relying on a demonstration recording provided by the vendor itself.

Frequently Asked Questions

What is the main difference between Otter vs Fireflies vs Teams Premium?

The biggest difference is platform flexibility. Otter and Fireflies work as a guest bot across almost any video platform, while Teams Premium only works inside Microsoft Teams itself.

Is Teams Premium cheaper than Otter or Fireflies?

It depends on your existing setup. For a business already paying for Microsoft 365 and standardised fully on Teams, Teams Premium can work out cheaper. For a mixed platform environment, a standalone tool is usually more cost effective overall.

Which AI notetaker has the most accurate transcription?

Otter and Fireflies both have strong reputations for accuracy, and Teams Premium benefits from direct access to the Teams audio pipeline. All three depend heavily on the quality of the room microphone being used.

Can Otter or Fireflies be used with Microsoft Teams?

Yes. Both tools can join Teams calls as a guest bot in the same way they join Zoom or Google Meet calls, which is one of their main advantages over a Teams-only tool.

Do these AI notetakers integrate with other business tools?

Fireflies is particularly strong on integrations with CRM and project management tools, Otter offers solid search and collaborative notes, and Teams Premium integrates most naturally with other Microsoft 365 applications.
