NotePin vs Vuzix Z100 in 2026

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.

Vuzix Z100

The Vuzix Z100 is an enterprise-focused monochrome-waveguide HUD smart-glasses device (38g, up to 48-hour battery), generally available since November 2024 at $499, aimed at warehouse, logistics, and field-service use with some consumer features (notifications, navigation, teleprompter) via the Vuzix Connect app. It has no native AI; any AI comes through partner integrations, placing it at the partner-mediated end of the AI-substance spectrum. Vuzix has been shrinking and pivoting toward OEM waveguide components; the Z100 is its current HUD product (the older Blade line is discontinued).
