If you run client calls for a living, you have probably tried at least one AI note-taking tool and been mildly disappointed. The transcript looks roughly right, the summary misses what actually mattered, and you still spend twenty minutes rewriting your notes anyway.
That is not bad luck. It is a setup problem. The three tools worth using in the UK right now - Otter.ai, Fireflies.ai, and Zoom Pro - each have a specific use case they are good for. Using the wrong one for your workflow is why it feels like none of them work.
This is a working comparison, not a spec sheet. We run discovery and assessment calls with clients every week. Here is what we have found.
Why meeting transcription matters more than people admit
Most consultants think of transcription as a nice-to-have - something that saves a bit of note-taking time. The real value is different.
When you have an accurate transcript of a client call, you can do three things you otherwise cannot:
- Find the exact phrase the client used when describing their problem, not your paraphrase of it
- Catch the thing they said in passing that turned out to be the most important detail
- Hand the call to someone else on your team without losing anything
For a 1-5 person consultancy, these are not abstract benefits. They are the difference between a report that feels like you were listening and one that feels generic. They are also the difference between spending 45 minutes writing notes after a call and spending 10 minutes reviewing an AI-generated summary and correcting two things.
The question is which tool gets you there, reliably, in a UK context.
Otter.ai
What it is
Otter.ai is the most widely recommended transcription tool in professional services. It runs on mobile and desktop, integrates with Google Calendar and Outlook, and can join Zoom, Google Meet, and Teams calls automatically via its "OtterPilot" bot.
What it does well
Transcription accuracy for standard UK English is good - not perfect, but reliably good enough to work from. It identifies speakers correctly most of the time once it has heard both voices for a minute or two.
The summary feature produces a short, readable overview of the main discussion points. For a 45-minute discovery call, you typically get a 150-200 word summary that covers the ground. It will not replace a proper debrief note, but it reduces the time you spend writing one.
The search function is useful. You can type a word or phrase and jump straight to the moment in the transcript where it was said. If you vaguely remember a client mentioning a particular tool or problem, you can find it in seconds.
What it gets wrong
Otter.ai struggles with regional UK accents. Scottish, Geordie, and strong Welsh accents produce noticeably more errors than standard southern English. If your clients are based in Glasgow or Newcastle, expect to spend more time correcting the transcript.
The free tier (300 minutes per month) sounds generous until you realise that a single hour-long client call plus a few team meetings will use it up in a week. The paid plan starts at around £8.33 per month for the Pro tier, which gives 1,200 minutes and removes the 40-minute cap per session.
The OtterPilot bot joining the call can occasionally unsettle clients who are not expecting it. Worth flagging in your booking confirmation that the call will be recorded and transcribed.
Best for
Otter.ai is the right choice if you are running calls primarily over Zoom or Google Meet, you want a standalone transcription tool that does not depend on your video platform, and your clients largely have standard southern or midlands English accents. It is also the simplest tool to set up - you can have it working in under ten minutes.
Fireflies.ai
What it is
Fireflies.ai is a more powerful tool aimed at teams. It joins calls as a bot (called Fred), transcribes in real time, and produces structured notes with action items, questions asked, and key topics. It integrates natively with CRMs including HubSpot and Salesforce, which is where it differentiates itself from Otter.
What it does well
The structured output is Fireflies' strongest feature. Rather than producing a wall of transcript text with a short summary at the top, it gives you:
- Chapters - the call broken into labelled segments
- Action items - tasks mentioned on the call, pulled automatically
- Questions asked - a list of every question raised, by either speaker
- Sentiment analysis - a rough read of tone at different points
For a consultancy that needs to move quickly from call to proposal, this structured output is genuinely time-saving. The action items list alone can save 10-15 minutes of post-call work.
Fireflies also handles multi-speaker calls better than Otter. If you run group sessions with three or four people speaking, speaker attribution is more reliable.
The CRM integration is the standout for anyone already using HubSpot. A call ends and the transcript, summary, and action items are pushed directly to the contact record within minutes. No copy-pasting.
What it gets wrong
The free tier is limited - you get transcription for up to three seats and limited storage. The useful features (CRM sync, unlimited storage, advanced search) require the Pro plan at around £8 per user per month, or the Business plan at around £16 per user per month for full CRM integration.
Accuracy is similar to Otter for standard English but drops similarly with strong regional accents. It is not meaningfully better or worse on this metric.
Some users find the structured output slightly over-engineered for solo consultants. If you do not use a CRM and just want a good transcript with a readable summary, Fireflies can feel like too much tool.
Best for
Fireflies is the right pick if you work in a team of two or more, you use HubSpot or Salesforce, and you want structured output (action items, chapters, questions) rather than a straight transcript. It is also the better choice if you run multi-stakeholder calls where speaker identification matters.
Zoom Pro
What it is
Zoom Pro is the paid tier of Zoom that most businesses use anyway once they need calls longer than 40 minutes. At around £11.99 per user per month, it includes cloud recording and - as of early 2026 - built-in AI Companion features that include automated meeting summaries and transcripts.
What it does well
The main advantage of Zoom Pro for transcription is that there is nothing extra to set up. If you already use Zoom for client calls - and most UK consultancies do - you already have access to cloud recording and AI summaries. There is no bot joining the call, no third-party integration to configure, and no additional monthly cost on top of what you are already paying.
Zoom's AI Companion produces a post-call summary that covers main topics and action items. It is not as structured as Fireflies, but it is clean and readable. The transcript is stored in your Zoom account and searchable.
Recording quality is also higher when the recording is native to the platform. You get a clean MP4 alongside the transcript, which is useful if you ever want to share a clip with a client or team member.
What it gets wrong
Zoom's transcription is only available for calls you host. If a client invites you to their Zoom room, you cannot use Zoom's own transcription tools - you would need to rely on Otter or Fireflies. This is a more significant limitation than it sounds for consultants who regularly join client-hosted calls.
The AI summary in Zoom Pro is less configurable than the alternatives. You cannot ask it to focus on specific topics or apply a particular structure to the output. You get what it gives you.
Zoom's UK data residency options are improving but worth checking if you handle sensitive client data. As of early 2026, EU data residency is available but requires the Business plan, not Pro.
Best for
Zoom Pro is the right choice if you already pay for Zoom, you host the majority of your calls, and you want transcription without adding another tool to manage. It is the simplest path for solo consultants who want "good enough" transcription without any integration work.
Side-by-side summary

| CRM integration | Limited | Strong (HubSpot, Salesforce) | Via Zapier only |
| Works on calls you do not host | Yes | Yes | No |
| UK accent handling | Good for standard English | Good for standard English | Good for standard English |
| Best for | Solo consultants, simple setup | Teams, CRM users | Zoom-native workflows |
Which one to pick
If you already pay for Zoom and you host most of your calls: start with Zoom Pro. You are already paying for it. Enable cloud recording, turn on AI Companion, and see if the summaries are good enough for your workflow. If they are, you have gained transcription without adding anything to your stack.
If you need to join client-hosted calls and want the simplest possible setup: Otter.ai. It works across platforms, takes ten minutes to configure, and the Pro tier is inexpensive enough that the per-minute saving is obvious within a week.
If you work in a team, use HubSpot, and want structured output that feeds directly into your CRM: Fireflies.ai. The setup investment is a bit higher but the automation value - transcript and action items landing in the contact record without manual work - pays for itself quickly if you are doing more than three or four calls a week.
The thing none of these tools do
Transcription is a useful starting point, but it is not the same as a workflow. Most consultancies that invest in a transcription tool find the same bottleneck a few weeks in: the transcript exists, but it still takes someone 20-30 minutes to turn it into a proposal, a follow-up email, or a structured set of notes to share with the rest of the team.
That is where AI agents come in - not to replace transcription, but to take the transcript and do something useful with it automatically. If that is the next problem you want to solve, it is exactly the kind of workflow we cover in a HoursBack Assessment.
