Editorial summaries
Xiaodu Pro AI Glasses
The Baidu Xiaodu Pro AI Glasses are camera-and-audio AI glasses with no display (explicitly not AR glasses): 39 grams, titanium hinges, a Sony 12-megapixel camera (4K photo, 1440p/30fps video), a four-microphone array, and prescription-lens support, in Boston and Cat-Eye styles. They went on sale in China on November 11, 2025 via JD.com and Tmall at 2,299 yuan, roughly $322, with next-day delivery. The AI is genuine and primary, built on Baidu's ERNIE large language model (first-person 'ask about what you see' Q&A, object and calorie recognition, encyclopedia lookup, audio and visual translation, reminders), and made via Baidu's Xiaodu Technology subsidiary; the assistant runs on ERNIE, not on Xiaomi's XiaoAI. They complete the Chinese consumer wearable-AI cohort alongside Xiaomi AI Glasses and the RayNeo V3. Cap-flag: pricing is China-market CNY (the USD figure is a conversion) and the glasses are not officially sold outside China; the AI is cloud-dependent rather than on-device.
NotePin
The Plaud NotePin (by Plaud.AI, San Francisco, founded 2023) is a lightweight wearable AI voice recorder worn as a clip, pendant, or wristband: a notes-pendant form factor distinct from the glasses, earbuds, necklace, and ring entries in the cohort. It taps to record meetings and conversations and uses third-party large language models (GPT, Claude, and Gemini) for transcription and AI summarization, and independent reviews confirm those core features work as advertised, placing it in the genuine-cloud-AI tier. It launched in August 2024 at about $169 with an optional Pro subscription, and a successor, the NotePin S, launched in January 2026 in the same price range. DEPLOY records it at commercial maturity: it ships, is purchasable, and is independently verified as functional, and it is a tier-1 citation winner in Google's AI Overview for 'best wearable AI' queries. Its model is subscription-augmented (a free tier plus a paid tier for more transcription minutes), the inverse of Hey Pocket's no-subscription-core posture. One cap-flag: Plaud's sales and revenue figures (more than a million devices, profitability, and $180-to-$250 million annualized revenue) are company self-reports, recorded as claimed rather than independently audited.
