My position

How I decide what belongs in this layer

This category must separate four different jobs that vendors often blur together: the device that captures a signal, the cloud or model that interprets it, the system that owns memory and retention, and the wearable runtime that can host an application. Bee Pioneer, Ray-Ban Meta, Fitbit, Claude, BNDT.ai, Wear OS, and Meta's developer platform do not occupy the same layer.

BNDT.ai is the primary owned control layer for listeners and wearable intelligence. Bee, glasses, watches, sensors, and model providers should remain replaceable sources, displays, runtimes, or processors around a portable session and data contract. Consent, indicators, provenance, deletion, and export are architectural requirements rather than footnotes.

The working set

7 tools, with the evidence level visible.

A field-note label is not a downgrade or a placeholder. It is the honest boundary between useful experience and a completed repeatable review.

Field notesOwned product / active development

BNDT.ai

An Android-first, device-agnostic wearable intelligence layer for ingesting audio and context from wearables or phones, creating controlled sessions, and turning them into transcripts, summaries, memories, tasks, and portable structured output.

Make BNDT.ai the primary control and intelligence layer; treat Bee, glasses, watches, microphones, and model providers as replaceable endpoints rather than the owners of the user's memory.Read the profile →

Field notesOwned device / field use

Bee Pioneer

Bee's wrist-or-clip ambient AI device captures conversations and voice notes, then turns them into summaries, reminders, tasks, patterns, and searchable personal context through its companion service.

Use Bee Pioneer as a practical ambient-capture benchmark and source device—not as the sole system of record or the permanent owner of wearable memory.Read the profile →

Field notesOwned device / field use

Ray-Ban Meta Smart Glasses

Consumer smart glasses combining first-person photo and video capture, microphones, open-ear audio, phone connectivity, and Meta AI for hands-free multimodal assistance.

Use the glasses for hands-free capture and situated AI experiments; do not confuse the consumer device you own with an open runtime for arbitrary applications.Read the profile →

Field notesOwned device / integration planning

Fitbit Platform

A wearable and cloud data source for activity, sleep, heart rate, HRV, SpO2, temperature, device state, and other consented health and fitness signals used by downstream applications.

Use Fitbit as a consented biometric data source, not as the assumed runtime for future apps; design now for the legacy Web API migration scheduled for September 2026.Read the profile →

Field notesPlanned device / active development target

Wear OS

Google's Android-based smartwatch application platform for standalone, phone-connected, or hybrid apps using watch interfaces, sensors, notifications, data-layer communication, tiles, widgets, and Google Play distribution.

Use Wear OS as the primary smartwatch runtime for apps you control, with the phone as a deliberate partner rather than an accidental single point of failure.Read the profile →

Field notesPlanned platform / developer preview

Meta Wearables Developer Platform

Meta's emerging developer surface for extending supported display glasses with mobile-connected or web experiences, separate from the closed consumer assistant workflow on existing Ray-Ban Meta glasses.

Track and test the developer platform separately from the glasses hardware; confirm supported models, APIs, distribution, permissions, and review rules before designing an app around it.Read the profile →

Field notesResearch / comparison target

PLAUD NotePin S

PLAUD's current button-operated wearable recorder for deliberate hands-free capture, with local audio storage and a companion Plaud Intelligence workflow for transcription, speaker labels, summaries, templates, highlights, web, desktop, mobile, export, and integrations.

Treat NotePin S as an explicit press-to-record professional capture device and Bee as the ambient-memory benchmark; compare both against BNDT.ai's requirement for portable sessions, model choice, export, and deletion.Read the profile →

Selection rules

The rules I use before adding another tool.

A consent-aware wearable system with owned data boundaries, reviewable inferences, replaceable endpoints, and applications that fail visibly and recoverably.

01Separate capture device, model, memory layer, and app runtime.
02Record consent, indicator state, provenance, and retention with every session.
03Confirm whether the device hosts apps or only mirrors a companion service.
04Keep export, deletion, and hardware replacement possible.
