Editorial summaries

Halliday (DigiWindow)

The Halliday glasses are display-first AI glasses built around DigiWindow: a roughly 3.5mm MicroLED projector on the inside of the upper-right rim that beams a monochrome green ~3.5-inch virtual display above the eyeline (a projection, not a lens waveguide), in ~35-gram conventional frames with no front camera, a touchpad, and an optional ring controller. Features include real-time translation (40 languages, demoed), notifications, navigation, a 'Cheat Sheet' teleprompter, and a 'proactive AI' Echo Mode. DEPLOY records it at pilot maturity: it launched via Kickstarter ($369 backer price, $489 retail) rather than full retail shipping. Its differentiator is the eye-projected display plus proactive AI, not eye-tracking (no eye-tracking is on record), and it has no camera. Cap-flag: the AI features and translation are demonstrated, and the ~8-hour battery is a vendor claim; verified shipping at scale is not yet established.

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.
