The Comu Action Pro is a standalone note-taking gadget that turns a simple idea into a dedicated device, positioning itself as an AI voice recorder for those who would rather not rely solely on the phone already in their pocket. Priced at roughly £140, it enters a growing category of single-use gadgets that promise to reduce dependence on smartphones while adding a specific, focused capability.
Pixel owners will already be familiar with the built-in Recorder app, which has matured over the years to include real-time transcription and translation, offering much of what you could want from software that uses a phone’s microphones. Against that backdrop, the Action Pro sets out to prove why separate hardware is worth the outlay.
Design and hardware
At 7mm thick, the Action Pro is a slim mixture of aluminium and plastic designed to attach magnetically to the back of a compatible phone, such as an iPhone or Pixel. The box includes a couple of circular magnetic stickers for devices without built-in MagSafe support. It is not as slender as the 3mm Plaud Note and Note Pro, but the added thickness brings clear advantages.
Chief among them is a USB-C port, so charging does not depend on a proprietary magnetic cable that could easily go missing. The extra size also accommodates a larger battery, pushing recording time to 70 hours, double that of the Plaud Note Pro.
Recording and microphones
The core question the device raises is why a separate piece of hardware is needed when a phone will suffice, particularly given the availability of inexpensive or free AI transcription services. The answer lies in its passivity. The Action Pro can be left running in the background throughout the day to capture snippets of conversation, or placed discreetly on a boardroom table to record a meeting.
The device carries six far-field microphones that pick up voices from distances phones are simply not tuned for. That omnidirectional design means the recordings themselves can sound thin and tinny, but the value is not in the audio quality. Instead, the product is built around the data extracted from that audio, using it to generate usable notes and transcripts.
Reviewed after extended use, the Comu Action Pro proves a capable meeting recorder, though its premium positioning against a well-equipped smartphone remains the central point of scrutiny. The current retail price stands at roughly £140.
