Fireflies.ai vs Microsoft Copilot: A First-Hand Comparison

I’ve spent the last six months living in both Fireflies.ai and Microsoft Copilot. Not just testing them for a review, but actually using them day in, day out for meetings, writing, and data work. I’m a project manager who also does content creation, so I need tools that save me time without making me fight the UI. Here’s my honest take after hundreds of hours with each.

Quick Intro

If you’ve ever sat through a 90-minute meeting and wished you could just get a bullet-point summary, you’ve probably looked at Fireflies.ai. It’s a dedicated meeting assistant that joins your calls, records everything, and spits out transcripts and summaries. It works across Zoom, Teams, Google Meet, and even Slack huddles. It’s laser-focused on one thing: making meetings less painful.

Microsoft Copilot, on the other hand, is an AI assistant that lives inside the entire Microsoft 365 ecosystem. It can draft emails in Outlook, analyze spreadsheets in Excel, create presentations in PowerPoint, and—yes—it can also summarize meetings from Teams recordings. But it’s not a dedicated meeting tool; it’s a general productivity copilot that happens to do meetings as part of a much bigger package.

I use both for different reasons. Fireflies is my go-to for capturing every word in client calls and internal stand-ups. Copilot is my Swiss Army knife for everything else—writing, data crunching, and the occasional meeting recap when I’m already in Teams. Let me break down where each shines and where they fall short.

Feature Comparison with Examples

Meeting Recording and Transcription

Fireflies.ai is a beast at this. It joins your meeting as a participant (it shows up as “Fireflies.ai” in the attendee list) and records everything. The transcription is near real-time, and you can see it scrolling live in the sidebar. I once had a 2-hour client discovery call where the client spoke fast, had a thick accent, and used industry jargon. Fireflies handled it like a champ—it even learned custom vocabulary I added (like “RFQ” and “stakeholder alignment”). The speaker identification is surprisingly accurate, even with overlapping speech.

Microsoft Copilot can only transcribe meetings that are recorded through Teams. It doesn’t join as a separate bot; it uses the existing Teams meeting recording feature. If you’re in a Zoom or Google Meet, Copilot is useless for recording. Even within Teams, the transcription quality depends heavily on the audio setup. I had a meeting where someone was on a bad headset, and Copilot’s transcript was riddled with “[]” placeholders. Fireflies would have flagged that and still given a decent guess.

Example: I had a weekly status meeting on Teams. Fireflies captured every “um” and “ah,” and I could search for “budget” across all my meetings. Copilot’s transcript was fine but didn’t let me search across multiple meetings—only within that one recording.

Summarization and Action Items

Fireflies.ai generates a “Magic Summary” after each meeting. It breaks down the conversation into topics, key points, action items, and even sentiment analysis. For example, after a tense negotiation call, Fireflies flagged “client expressed frustration about timeline” as a sentiment insight. It also extracts action items automatically and can push them to Asana or Jira. I’ve had times where I forgot to take notes, and Fireflies’ summary was good enough to forward to the team.

Microsoft Copilot can also summarize Teams meetings, but it’s more limited. You have to be in the meeting recording or the “Meeting Recap” section in Teams. The summary includes action items, but they’re not as granular. Copilot might say “discussed project timeline,” while Fireflies would say “John proposed extending the deadline to Q3, Sarah disagreed, and they agreed to revisit next week.” Copilot’s summaries are shorter and sometimes miss nuance.

Example: After a 45-minute sprint retrospective, Fireflies gave me a 300-word summary with 5 action items, each tagged to a person. Copilot gave me a 100-word summary with 2 action items, and one was wrong (“update documentation” when we actually decided to postpone it). I had to manually correct it.

Search and Discovery

Fireflies.ai has a powerful search engine. You can search across all your recorded meetings by keyword, date, speaker, or even specific phrases. I once needed to find a client’s exact words about a pricing objection from three months ago. I typed “pricing” into Fireflies, and it showed me every instance across 50+ meetings, with timestamps and context. It also has a “Soundbites” feature that lets you clip short audio snippets to share.

Microsoft Copilot has search, but it’s limited to meetings within your Microsoft 365 tenant. It can’t search across your entire meeting history unless you’ve recorded everything in Teams. Even then, the search is more like “find this keyword in this meeting” rather than a cross-meeting search. Copilot’s semantic search is better for documents—it can find a phrase in an email, a Word doc, and a meeting transcript, but it’s not as meeting-focused.

Example: I searched “deliverable deadline” in Fireflies and got 12 results from 8 different meetings, each with a 30-second audio clip. In Copilot, I got 3 results from the same meeting recording, and no audio.

Integrations and Workflow

Fireflies.ai integrates with 50+ tools. I have it connected to Slack, Asana, Salesforce, and Notion. When a meeting ends, Fireflies can automatically create a task in Asana, log the call in Salesforce, and post a summary to a Slack channel. It’s a huge time-saver for sales teams. I also use the Zapier integration to trigger custom workflows, like sending a summary to a Google Doc.

Microsoft Copilot is deeply integrated into Microsoft 365, but that’s both a strength and a weakness. It works seamlessly with Outlook, Word, Excel, and PowerPoint. I can ask Copilot to “summarize this week’s emails” and it pulls from my inbox. But if you use non-Microsoft tools (like Slack, Notion, or Asana), Copilot is blind. It can’t push data to those platforms natively.

Example: After a client call in Zoom, Fireflies automatically added a note to the Salesforce opportunity and sent a summary to the Slack channel. Copilot couldn’t even join the Zoom call. For a Teams meeting, Copilot could create a summary in Word, but I had to manually copy it to Slack.

Customization and Learning

Fireflies.ai lets you create custom vocabulary, set meeting topics, and even define “trackers” for specific keywords. I set up a tracker for “budget increase” and “competitor name,” and Fireflies alerts me whenever those are mentioned. It also learns your preferences over time—if you always mark certain types of meetings as “high priority,” it starts prioritizing them in search.

Microsoft Copilot doesn’t have per-meeting customization. It uses the same AI model across all apps. You can’t teach it to look for specific terms in meetings. It does learn from your Microsoft 365 data (emails, documents, calendar), but that’s more about personalization for writing and analysis, not meeting-specific tuning.

Example: I set up a tracker in Fireflies for “renewal date” and it caught a client mentioning it in a casual conversation. Copilot would never flag that unless I explicitly asked it to search for it after the meeting.

Pros and Cons

Fireflies.ai

Pros:

• Works across virtually every meeting platform (Zoom, Teams, Google Meet, Webex, etc.)
• Incredibly accurate transcription, even with accents and jargon
• Powerful search across all meetings with audio clips
• Action items and summaries are detailed and actionable
• Affordable pricing for individuals and small teams
• Excellent integrations with non-Microsoft tools (Slack, Salesforce, Asana, etc.)
• Custom vocabulary and trackers make it adaptable to your industry

Cons:

• No features outside of meetings (can’t write emails or analyze data)
• The bot shows up as a participant, which some clients find intrusive (though you can rename it)
• Free tier is very limited (only 1 meeting per day, limited credits)
• No native desktop app; it’s a web app and browser extension
• Summaries can be verbose—sometimes too much detail for quick reviews

Microsoft Copilot

Pros:

• Deep integration with Microsoft 365—feels like a native part of the suite
• Can do far more than meetings: draft emails, create presentations, analyze Excel data
• Summaries in Teams are clean and formatted for quick reading
• Good for enterprise users who live in the Microsoft ecosystem
• No extra bot to add to meetings (uses existing Teams recording)
• Can pull context from your emails, documents, and calendar

Cons:

• Only works with Teams meetings (no Zoom, Google Meet, etc.)
• Transcription quality is inconsistent, especially with poor audio
• No cross-meeting search—you can’t find a phrase across all your recordings
• Very expensive at $30/user/month, especially if you only need meetings
• Limited customization for meeting-specific needs (no trackers or custom vocabulary)
• Requires admin setup and often Teams Premium for full meeting features
• Summaries are often too brief and miss important details

Verdict with Winner

If I had to pick one for my daily work, it would be Fireflies.ai. Here’s why: I spend a lot of time in meetings across different platforms—Zoom with clients, Teams with internal teams, Google Meet with partners. Fireflies works everywhere. Its transcription accuracy, search capabilities, and integration with my non-Microsoft tools (Slack, Asana, Salesforce) are indispensable. The custom trackers alone save me hours of manual note-taking.

But I can’t ignore Microsoft Copilot’s strengths. If you’re an enterprise user who lives in Outlook, Teams, Word, and Excel, and you rarely use Zoom or Google Meet, Copilot is a powerful all-in-one assistant. It’s not just a meeting tool; it’s a writing, analysis, and presentation tool. The $30/month price tag is justified if you use the full suite. But for meeting-specific work, it’s overpriced and under-featured compared to Fireflies.

Winner: Fireflies.ai for meeting capture, transcription, and search. It’s the best dedicated meeting assistant I’ve used.

Runner-up: Microsoft Copilot if you’re all-in on Microsoft 365 and want an AI assistant that does meetings plus everything else.

My personal setup: I use Fireflies.ai for all meetings (Zoom, Teams, Google Meet) and keep Microsoft Copilot for drafting emails and analyzing spreadsheets. They complement each other well, but if I had to cut one, I’d keep Fireflies. Meetings are where I lose the most time, and Fireflies gives me that time back.
