The Limitless Pendant is a wearable that records your life. Clip it to your shirt, go about your day, and the AI transcribes every conversation, meeting, and idea and stores it in a searchable archive. The device is called a Limitless Pendant. The company was previously called Rewind. Before that it was called Scribe. They keep naming themselves after memory.
What it actually is
It is a small circular device, roughly the size of a quarter, designed by the same team behind Beats by Dr. Dre headphones. It clips magnetically to your shirt or hangs as a necklace. It records everything it hears, syncs over Bluetooth to the Limitless app on your phone, and the AI turns that audio into what the company calls a Lifelog: a running transcript of your day, broken into summaries, searchable by conversation or date. The free plan gives you 20 hours of transcription per month. Everything else, notes, summaries, AI queries, is free. It works on iOS, Android, Mac, and Windows.
The consent light
Here is the part the marketing addresses carefully. The pendant has an LED that lights up when it is recording. Limitless calls this consent mode: the idea is that the light signals to people nearby that audio is being captured. The pendant records continuously by default, which means it is recording the barista, the doctor, the person who sat next to you on the train, and anyone else within earshot, unless you pause it. Some of those people will see the light. Most probably will not. The help documentation notes you can delete recordings from the app at any time, which is a useful clarification, and also suggests that this is a thing you might need to do.
Who it is actually for
The honest use case is work. Meetings you cannot take notes in. Client calls where you want a record. Ideas that come to you while your hands are busy. For that specific problem, a wearable that passively captures audio and returns clean transcripts is a legitimate tool, and the 20-hour free tier is generous enough that most people will not need to pay.
The existential pitch, that this is your external memory, your augmented recall, your permanent record of being alive, is more complicated. If you find yourself needing to search a transcript to remember what a friend told you, the pendant is probably not the part of that situation that needs solving. But the work case is real, the hardware is reportedly solid, and it is backed by Andreessen Horowitz, Sam Altman, and First Round Capital, which at minimum means someone serious thinks the category is worth building. If your concern runs the other direction, Proton Drive is built on the opposite premise: the company holding your data cannot read it.
The company that made it was called Rewind because it let you replay your life. Now it is called Limitless. The product is a pendant you wear around your neck to remember things. The name keeps changing. The idea keeps getting more ambitious. The light keeps blinking.
