The Limitless Pendant is kept here because it set the standard this category is still measured against on one specific question — how a device tells the people around you that it is recording — and because its ending is the most useful cautionary tale available to anyone buying an AI wearable.
It is unranked. This ranking orders shipping devices only, and Limitless stopped selling the Pendant on 5 December 2025.
What it got right
The recording light. A white LED came on whenever the Pendant was recording, and Limitless documented plainly that “for privacy reasons, there is no way to dim or turn off the light entirely”. Obscuring it was a terms-of-service violation. On a device designed to record continuously, that is the difference between a wearable and a bug, and Limitless was unambiguous about which it was building.
The second thing was data access. Limitless shipped a full export feature, a documented REST lifelogs API and a hosted MCP endpoint, so the record it built of your life was readable by tools you chose rather than only by its own app. Very little else in this category does that.
The third was 35 hours of on-device speech buffering — it stored audio only when it detected a voice, so a day away from your phone did not mean a day of lost capture.
What happened
Meta acquired Limitless and announced it in December 2025. Sales ended on 5 December. Existing owners were given the Unlimited plan free, which is a decent way to treat customers, but support is committed only “throughout 2026”. Service was withdrawn outright in Brazil, China, the EU, Israel, South Korea, Turkey and the UK, with accounts in those regions deleted after 19 December 2025. This page encodes $0/month because that is the current manufacturer position, not because the Pendant never had a software plan. Limitless’s own Pendant FAQ still describes a Free plan of 1,200 transcription minutes a month with paid Pro and Unlimited upgrades; those prices are no longer offered, and this page does not invent them.
Note also the specification that quietly moved. At launch, the Pendant was announced with a 100-hour battery. Limitless’s current help centre says only that it “will get you through a full day of continuous recording” and recommends charging every night. Those two claims differ by roughly a factor of four and the gap has never been publicly reconciled, which is why this page lists no battery figure at all.
What to take from it
If you are buying a device in this category from a company that has not yet proved it will exist in three years, assume the cloud service behind it can stop. The devices here that survive that test are the ones that transcribe on your own hardware — Omi’s free tier and the Pebble Index 01 — and the ones that let you get raw files out before the lights go off.
