I had low expectations for the rather generic Comulytic Note Pro, but it surprised me as not only the most useful all-around note taker available but also the cheapest after you factor in the cost of the premium subscription.
The slim device, weighing 28 grams, is small enough to slip into a wallet or attach unobtrusively to the magnetic ring included on the back of your phone (note: requires a special USB dongle to charge). The 64GB of storage and 45 hours of battery life aren’t huge, but both should be more than enough to handle a full week of interviews without discharging or recharging, all of which is handled through OpenAI’s GPT-5 and Google’s Gemini. The small LCD screen is useful (and rare in this market), as it indicates recording time and displays the recording duration. This makes it much more reliable than other note takers, which only offer a colored LED to let you know if it’s on.
The Note Pro supports 113 languages, sort of. Recording will be in a foreign language and a verbatim transcript will be provided in the native language, but ideas and summaries will be presented in the language of your choice. It’s not a complete solution if you need a full, straightforward translation, but if you just need the gist of a news story or foreign speech, Comulytic can uniquely handle it.
The evidence is in the quality of the summaries and ideas presented. Of all the devices I tested, Comulytic’s summaries were the most insightful and least cluttered (though better than their transcripts), effectively picking out the most relevant parts of interviews and extracting the best quotes from my conversations (perhaps sometimes too many). It was also the only device to correctly transcribe a trivial nickname for a product mentioned in passing in an interview, suggesting that there may be a more sophisticated language model behind the scenes.
Komolytic is not perfect. It doesn’t transcribe in real time, it’s one of the slowest products to complete analyses, and I’ve never been able to get its “hot transfer” mode to work, which means all recordings have to be sent to my phone via a Bluetooth connection, but those are minor knocks against an otherwise solid solution. Best of all, the company offers, for a limited time, three months of premium service for free. Even if you don’t want to subscribe, the free plan, which offers three “deep dives” and 10 summaries per month, is better than nothing.
The subscription costs $15 per month or $120 per year
