The practice of taking voice notes or recording meetings is not new. But you could say that it’s one thing that the AI boom has super-charged. Creating coherent notes, action items, and summaries has never been easier, and recording meetings, lectures, or just thoughts now makes more sense than ever.
And while you can find an app or tool to do that with, nothing beats dedicated hardware for the job.

The Comu Action Pro is a slim, pocket-sized, AI-powered voice recorder that can stick to the back of your phone via MagSafe or spend its time on a conference table to capture, transcribe, and analyze conversations.
While at its core it’s a voice recorder that saves audio files, the Action Pro then takes things further with end-to-end AI agent tools. And the recorder specifically has a dedicated AI button to make it easy to input your requests or queries with zero friction.

The Comu AI assistant is your best friend to record, transcribe and annotate meetings. Multi-language team? Not a problem, it can also translate audio across 113 different languages.

Yes, we’ve seen AI recorders that do auto-transcribing before. What sets Comu apart is the hardware AI button, placed there to make it super-easy for you to engage with your notes and queue requests.
Hold the button down and speak natural language prompts directly to the device, like "Draft a follow-up email from this" or "Create a presentation" or “Add the discussed dates to my calendar”, and it will automatically get to work inside the Comu app on your phone. Then, you can check the drafts and confirm the actions at your leisure.
Also, transcripts are great, but sometimes even they can get long and messy. You can ask the Comu AI specific questions about discussions within a recorded meeting and you will get your answers within the app.
Notes are also multi-modal, meaning you are free to attach photos, slides, schematics, to specific parts in the audio timeline, so they flow with the meeting recording when you revisit it later.

The Comu Action Pro is not just a microphone box that you speak into. It has six microphones for far-field quality audio capture and noise suppression.
Four microphones on its sides pick up speech from multiple speakers, and the AI can recognize the different voices. There’s a 5th “main” microphone that you can direct towards a main speaker for the clearest recording.
And then the sixth mic is a conduction sensor. It serves two purposes. One, when it’s attached to your phone, it can record phone calls through the vibrations picked up from the back of your phone. Secondly, it will passively assist in noise pickup and reduction when the Action Pro is sitting on a meeting table.
Dedicated hardware with its own dedicated memory

If you work with a flexible team that does a lot of decision-making in live meetings or if you are a student that needs to record way too many notes, by now you should see the need or at least understand the value of having a dedicated hardware piece that’s always ready to go.
No need to fish for an app or look through a bunch of recordings, all named with random dates or locations that your phone picked up. A dedicated recorder is ready to go with the push of a button.
And the Comu Action Pro has on-device memory, so you can continue recording while your phone is out of reach. Syncing, transcription, and AI features take place through the Comu app when the phone is available.
The small display is just enough to give you status information about the device — battery level, recording status, memory — without being a distraction. And its size and weight make it convenient to always have on you.
Don’t have an iPhone? Not a problem — it has a sticky mag ring in the box!

If you own an iPhone it’s easy to always have your Comu Action Pro with you — it sticks to the MagSafe ring on the back. Same with a Pixel phone thanks to Pixelsnap.
If you happen to have any other handset and still want to enjoy having the Comu Action Pro hang out on the back of your phone, you can. A self-adhesive magnetic ring can be found in the box, giving any smartphone the ability to latch on to the Comu.
