Comu Action Pro Review: Can It Beat Plaud Note?
AI wearables are a strange category. I've tested quite a few AI gadgets over the past couple of years, and while some are genuinely useful, others seem to exist mainly because adding AI to a product makes it easier to sell.
AI voice recorders are different.
Plaud Note was one of the first AI wearables I used that genuinely made sense to me. Record a conversation, turn it into a transcript, pull out the important information and move on. Simple.
So when I started testing the Comu Action Pro, I was particularly interested to see whether it could offer anything better.
After using it almost every day for two weeks, I think it can.
I've used the Action Pro at home for notes and research, while walking my dog, and more seriously during Salon Privé at Blenheim Palace, where I interviewed people from several interesting car brands. I later used those recordings to help gather information for my article about the event.
That last example was probably the best test I could have given it. Salon Privé was busy, there were people everywhere and it was certainly not a controlled environment.
The Comu Action Pro performed remarkably well.
And while Plaud remains the obvious comparison, I've come away feeling that Comu has created something that is better in several important areas.
Quick Verdict
After two weeks of almost daily use, I think the Comu Action Pro is one of the most convincing AI recorders I’ve tested so far. The hardware feels more premium than Plaud Note, transcription is extremely fast and accurate, and the app has been simple and intuitive from the start.
The biggest advantage, though, is unlimited basic transcription. If you record meetings, interviews or ideas regularly, that makes the Action Pro much easier to live with long term.
Plaud still has an edge for larger companies because its privacy and compliance framework is more mature. But for freelancers, creators, entrepreneurs and individual users, I would currently choose the Comu Action Pro.
Design: This Is Where Comu Immediately Won Me Over
The small display is simple, but I found it genuinely useful for checking battery level and recording status.
Design is subjective, but I prefer the Comu Action Pro to the Plaud Note.
Quite considerably, actually.
The Action Pro feels more premium. It is made from aluminium and plastic, measures around 7mm thick and attaches magnetically to the back of a compatible phone. That makes it thicker than the extremely slim Plaud Note, but I don't see that as a major problem.
Attached to my iPhone 17, it looks excellent.
The magnetic connection is very strong and I never felt that it was about to move or fall off. There is also a small display, which is simple but genuinely useful, and the physical buttons have a satisfying click.
This sounds like a small detail, but with products like this I don't want to spend time wondering whether recording has actually started. I want to press a button and know.
There's also USB-C charging, which I much prefer to another proprietary cable. When you travel with as much technology as I do, one less cable matters.
Comu claims up to 70 hours of recording from a charge. I haven't sat down and recorded continuously for 70 hours to verify that figure, and frankly I don't think many people will.
What I can say is that battery life has been excellent. I used it extensively during Salon Privé and regularly throughout my two weeks of testing without battery anxiety.
Recording Quality: Salon Privé Was the Real Test
Most of my normal use isn't especially demanding.
I often record something while working at home during the day, when the house is relatively quiet. I've also taken it with me while walking Marlow, my cocker spaniel, when I want to capture an idea.
Neither situation is particularly difficult for a modern recorder.
Salon Privé was different.
There were conversations taking place around me, people moving constantly and plenty of background noise. I interviewed people involved with some of the car brands there, and these were conversations I actually needed afterwards.
Comu uses a six-microphone recording system designed to capture voices in different environments.
In my experience, it works.
I was surprised by how well the Action Pro dealt with that noisy environment. More importantly, the resulting recordings gave the transcription engine enough information to produce very accurate text.
The Transcription Is Excellent — And Very Fast
This may be the part of the Comu Action Pro that impressed me most.
Transcriptions appear remarkably quickly after a recording, and accuracy during my testing has been excellent.
I also gave it a slightly more interesting challenge.
I'm French, so naturally I tested it in French.
The transcription was essentially 100% accurate. No problems with my accent, no strange interpretation of words and no obvious mistakes.
In English, I'd put my results at around 99%. The occasional mistake was usually connected to my French accent rather than anything particularly complicated.
My wife is British, so I asked her to test it too.
With her English accent, the transcription was effectively perfect.
Comu supports 113 languages, so multilingual transcription is clearly an important part of the product rather than an afterthought.
The AI Button Is Better Than I Expected
Above the standard recording control is a dedicated AI button.
Initially, I wasn't sure how much I would use it.
You can speak directly to Comu and ask it to work with the information you've captured.
For example, I asked:
“What is best about the Comu Action Pro? Tell me in two lines.”
Its answer was:
“Comu Action Pro captures what matters, in the moment and helps turn it into clear useful actions. It keeps you focused, organised and moving forward without interrupting your flow.”
Not bad at all.
More importantly, being able to ask naturally rather than going through several menus suits this type of device. The whole point of an AI wearable is that it should reduce friction.
Emails, Documents, Presentations and Action Lists
This is where Comu tries to move beyond being simply an AI recorder.
It can use your recordings to create emails, documents, presentations, action lists and other outputs. Comu currently works with several AI models, with Claude included on its paid plans.
I tested all of them. I found the email generation particularly good. I selected Claude, gave it the information from my recording and the resulting email was perfectly usable.
If your working day involves moving from meeting to meeting, I can immediately see the appeal. You finish a conversation, Comu extracts the important points and helps draft the follow-up without you reconstructing the meeting from memory later.
That's where the word “Action” in Action Pro starts making sense.
Recording Phone Calls
I also tested a telephone call with my wife.
The strong magnetic attachment meant the Action Pro stayed securely positioned on my iPhone, and the subsequent transcription was extremely accurate.
I don't personally have much need to record phone calls, but it's reassuring to know that the feature works properly if I ever need it.
There is an important point here, though: privacy matters.
Recording laws and consent requirements vary between countries and situations. If you're recording another person, particularly on a telephone call, make sure they know they're being recorded where consent is required.
The Subscription Model Is a Big Advantage
This is where Comu becomes particularly interesting compared with Plaud.
Comu's free Starter plan currently offers unlimited basic transcription and basic summaries. Premium costs $10 per month when billed annually, or $14.99 monthly, and adds more advanced AI capabilities and 5,000 monthly Agent Credits.
Plaud's free Starter plan, by comparison, currently includes 300 transcription minutes each month.
If you only record occasionally, 300 minutes may be perfectly adequate.
If you're regularly interviewing people, attending meetings or recording ideas throughout the day, however, those minutes can disappear surprisingly quickly.
I prefer Comu's approach: let people record and transcribe freely, then charge for the more advanced AI functions.

Comu Action Pro vs Plaud Note: Which Would I Buy?
Plaud deserves a lot of credit. It was one of the first AI wearables I used that felt genuinely useful rather than simply interesting, and I still think it is an excellent product.
For my own use, though, I now prefer the Comu Action Pro. I like the hardware more, I prefer the design of the app, and unlimited basic transcription is a significant advantage if you use an AI recorder regularly.
There is one important area where Plaud remains ahead, particularly for business users: privacy, security and compliance.
To be clear, Comu isn't ignoring privacy. The company states that its platform complies with GDPR, HIPAA and SOC 2, uses encryption to protect files, doesn't sell user data to third parties and doesn't use recordings to train AI models. That's reassuring for me as an individual user.
Plaud, however, currently has a much more extensive and transparent compliance framework. It is certified to ISO/IEC 27001:2022 for information security management and ISO/IEC 27701:2019 for privacy information management. It also lists SOC 2 Type II, GDPR, HIPAA and the European EN 18031 cybersecurity standard. Plaud publishes information about regional data storage too, with European user data stored on AWS infrastructure in Frankfurt, for example.
That difference may not matter very much to someone like me using an AI recorder for interviews, ideas and research. But if I were buying hundreds of these devices for a company, recording confidential meetings or dealing with sensitive customer information, it absolutely would.
So my choice is fairly straightforward. For individual users, freelancers, journalists, creators and entrepreneurs, I prefer the Comu Action Pro. For a larger company or enterprise environment where formal security certification and data governance are major considerations, Plaud would still be my choice today.
Final Thoughts
The Comu Action Pro is a very good example of where AI hardware is heading.
It isn't trying to replace your smartphone, and it doesn't need to.
Instead, it does one job particularly well: it captures conversations and ideas, turns them into accurate text and then gives you tools to do something useful with that information.
After two weeks of almost daily use, including a demanding day interviewing people at Salon Privé, I trust it.
I prefer its design to Plaud, transcription has been exceptionally good in both French and English, the app has been straightforward to use and unlimited basic transcription makes the overall proposition much easier to recommend.
Plaud remains my choice for larger organisations where its broader privacy and compliance framework becomes an important part of the purchasing decision.
But for someone like me — self-employed, moving between interviews, events, research and content creation — I think the Comu Action Pro currently makes more sense.
And perhaps that's the biggest compliment I can give it.
I started testing it wondering whether I really needed another AI recorder.
Two weeks later, I don't particularly want to give it up.
