Editors' review
The one where the hardware price is the whole price
Every other option in this category assumes a subscription behind it. Comu does not, and for anyone transcribing a lot that inverts the arithmetic. The official site is explicit that transcription and basic summarisation are free and unlimited.
Be precise about where free ends. Turning a recording into a document or extracting next actions uses credits, and the free tier caps them. Decide which half of the product you actually need before buying.
At JPY 39,800 list it is roughly double Notta Memo, which is the trade for having no monthly fee. Against a service costing a little over ten thousand yen a year, the total cost crosses over somewhere in year two or three — run that number for your own volume.
Verdict
The right answer if you refuse another subscription and transcribe often. Do the arithmetic first if you already pay for a meeting-notes service.
