Comu Action Pro review

I love doing interviews, chatting to developers and such, but I absolutely hate having to transcribe them afterwards. Not because of my company, of course, but the prospect of listening to my own voice on recording fills me with a dread I still haven’t got over in my grand old age. Not only that, but transcribing is a painstakingly tedious process that, before suitable programs came in to help us, we used to do by listening to said recordings at half speed and trying to pick out suitable quotes. Now, there are plenty of tools to help, including the Comu Action Pro, a sleek device that records and transcribes audio on the fly.

Transcribing is the perfect task for AI

While there are plenty of reasons to curse AI, handling banal tasks such as this for me is one of its genuine godsend use cases and something I’ve been using Otter.ai for, for quite some time.

Now Otter.ai is fantastic, but it’s also bloody expensive. You get 3 free audio imports, and that’s it; after that, you have to cough up $16.99 a month (or pay $100-ish for the year). Well, guess who was on her 7th burner email address and forgot to cancel her « free trial »? This person right here.

To make this mistake sting even more, I was introduced to the Comu Action Pro not long after the yearly, yes, YEARLY Otter.ai fee had left my bank account. Alas, I had the opportunity to really test them against each other, so every cloud has a silver lining and all that.

What is Comu Action Pro?

The Comu Action Pro (also known as the less catchy Comulytic TN20) is a sleek, credit card-sized device which slides right into your pocket or bag. It does cost $169.99, and I know what you’re thinking: damn, that’s expensive, and you were just complaining about the Otter subscription. However, it’s a one-off up-front spend for something that will then transcribe unlimited audio files for you, with no subscription required. Despite my hefty payment to Otter, I am still limited to 10 imports a month, which soon got swallowed up with an event like Gamescom.

Spec-wise, for such a tiny, unassuming-looking device, it packs a 6-microphone adaptive array, a live AMOLED waveform display, USB-C charging, real-time translation across 113 languages, and a massive 60+ hour battery life.

To be upfront, there are optional premium subscriptions for extra AI magic you can use with Comu, like automatic slide generation and generating meeting minutes, but I’m not interested in that; I just wanted the core transcription, which it handles beautifully and without ongoing subscription fees. Yes, $169.99 is a mighty hefty upfront cost, but it’s the price I pay for having a personal assistant without being locked into a recurring monthly fee.

What’s free and what isn’t

If you want to use the Comu Action Pro to its full AI potential, here’s a breakdown of what is free and what requires a subscription (but to be clear, I haven’t used the latter because I was trying to find an alternative to subscriptions!).

Using the Comu to make my work much easier

I’ve put the Comu through its paces at both Gamescom and Blizzcon this year, and it’s safe to say it’s earned its keep. I haven’t had to worry about upload caps, and I’m not constantly fiddling with my phone on a busy show floor trying to launch the voice recorder app. The Comu is a simple hit-a-button device: hit the button to record; hit it again to stop. The recording then uploads to the app and transcribes to my phone. It’s been a huge relief for me rushing between developer appointments.

The included software with Comu has also been a win for my colleagues. I wasn’t sure I could use it for audio not recorded on the device, but it works just as well with files sent to me from other people’s phones and has handled them with an impressive degree of accuracy, even though they were recorded in less-than-perfectly staged environments. It’s certainly more accurate when picking up audio with its own mics, but given the deafening background noise at conventions, I’ve been impressed by how few words it has messed up. Plus, I actually had the conversation myself; you would hope I could spot and correct myself when something is relayed not quite as what was said!

Ultimately, the Comu Action Pro has quickly become an essential part of my travelling gear bag. It spares me hours of manual transcription and delivers reliable, local-first audio capture without locking me into a subscription. There are various extras you can use and pay for if you are interested, but I didn’t have a use case for testing them in this review; I prefer to keep AI for the boring tasks rather than the creative ones.

If you do a lot of in-person reporting and hate transcribing as much as I do, this little card is worth checking out.
