The market for AI-powered notetakers is exploding, offering devices that can record, transcribe, and analyze meetings, interviews, or lectures. While many options exist, some stand out for their features, cost, and overall usability. This review breaks down four leading contenders: Comulytic Note Pro, Pocket, InnAIO T10, and OSO AI Earbuds, detailing their strengths and weaknesses.
Comulytic Note Pro: The Value Pick
The Comulytic Note Pro emerges as the most practical and affordable option. Weighing just 28 grams, this device is discreet and portable, easily fitting in a wallet or attaching magnetically to smartphones. It boasts 64 GB of storage and a 45-hour battery life – sufficient for extended use without frequent charging. The Note Pro utilizes both OpenAI’s GPT-5 and Google’s Gemini AI models, delivering accurate transcripts and insightful summaries in 113 languages.
Despite its small size, the device includes a rare LCD screen that clearly indicates recording status. While analysis isn’t real-time, the summaries provided are notably sharp, extracting key quotes and insights effectively. A limited-time promotion includes three months of premium service, even with the free plan offering three “deep dives” and ten abstracts monthly.
Subscription costs: $15/month or $120/year.
Pocket: High Capacity, but Bulky
The Pocket offers more storage (128 GB in newer models, 64 GB in older) and longer battery life (96 hours) than the Comulytic. Its magnetic attachment is seamless for MagSafe or Qi2 smartphones, and a dedicated switch allows discreet phone call recording. Transcriptions and summaries are quick, completed in roughly half the time of Comulytic.
However, Pocket’s physical button is unreliable, sometimes requiring multiple presses. The LED indicator is hard to see, and exported files in Word format are prone to corruption. The free plan limits history to 14 days and throttles exports. The premium Pocket Pro plan is expensive for the value it delivers. The larger size also makes it less convenient than Comulytic.
Subscription costs: $20/month or $200/year.
InnAIO T10: The Multilingual Specialist
The InnAIO T10 prioritizes language translation over general notetaking. This 33-gram device can transcribe in both your native language and a chosen second tongue, though translation cannot be disabled. Offline mode is now functional, but relies on GPT-4.1 instead of the newer GPT-5.
The T10’s free plan is restrictive, offering just 120 minutes of real-time translation monthly. Unlimited use is costly at $25/month or $179/year. While imperfect, it remains the best option for frequent multilingual transcription needs.
Subscription costs: $25/month or $179/year.
OSO AI Earbuds: Niche, but Limited
OSO AI Earbuds uniquely transcribe audio through earbuds rather than recording ambient sound. This makes them ideal for capturing phone calls and personal conversations. However, battery life is short (four hours), and the system lacks physical controls, relying solely on a finicky app. Transcriptions aren’t real-time, and app glitches can abort recordings.
The free plan is severely limited (300 minutes monthly), and even the subscription only offers 2,000 minutes monthly. Summaries are basic. Competition in this space is expected to intensify.
Subscription costs: $16/month or $120/year.
The choice of an AI notetaker depends heavily on your needs: Comulytic excels in affordability and usability, Pocket offers high capacity but is bulky, InnAIO T10 specializes in multilingual translation, and OSO AI Earbuds suit niche earbud-based recording. Ultimately, the Comulytic Note Pro represents the best balance of features, price, and convenience for most users.
