Pebble<\/a> (Hacker News<\/a>):<\/p>\n

Introducing Pebble Index 01 - a small ring with a button and microphone. Hold the button, whisper your thought, and it’s sent to your phone. It’s added to your notes, set as a reminder, or saved for later review.<\/p>

Index 01 is designed to become muscle memory, since it’s always with you. It’s private by design (no recording until you press the button) and requires no internet connection or paid subscription. It’s as small as a wedding band and comes in 3 colours. It’s made from durable stainless steel and is water-resistant. Like all Pebble products, it’s extremely customizable and built with open source software.<\/p>\n

What if the speech-to-text processing misses a word or something?<\/p>\n

You can always listen to the each recording in the app.<\/p><\/blockquote>\n\n

This sounds good, but I don’t want another device. I try to do this with my Apple Watch, but it doesn’t work as well as I’d like. Apps, of course, can’t repurpose any of the hardware buttons. I don’t know of a complication that lets you just press a button to record audio to be transcribed as text. The Reminders complication takes 4 taps (complication, Add Reminder, microphone button, Done) to add a reminder via voice. Siri works without any taps but often screws it up by trying to interpret what I said. If I mention anything that sounds like a meal, a time, or a location, I might end up with that text removed and instead have the time and location fields set on the reminder for when I arrive at that place, which is never what I want. This also seems to confuse OmniFocus and prevent it from importing the reminder.<\/p>\n\n

There’s no way to recharge the ring. Migicovsky says he didn’t want yet another gadget to charge every day, so instead, the Pebble Index has non-rechargeable silver oxide hearing aid batteries designed to last two years with average use. Once the device’s battery is nearly dead, users will receive a notification in the app, and the idea is you’ll buy a new Pebble Index—an idea that’s easier to get behind knowing the ring costs just $75, though the price will jump to $99 after the first batch.<\/p><\/blockquote>\n\n

Core Devices, the new home of Pebble, says the Index is designed to be worn on your index finger (get it?), where you can easily mash the device’s button with your thumb. Unlike recording notes with a phone or smartwatch, you don’t need both hands to create voice notes with the Index.<\/p>\n

After you record a voice note, it’s beamed over Bluetooth to your phone (Android or iOS), and it stays there. The recording is converted to text and fed into a large language model (LLM) that runs locally on your device to take actions. The speech-to-text process and LLM operate in the open source Pebble app, and no data from your notes is sent to the Internet. However, there is an optional online backup service for your recordings.<\/p>\n<\/blockquote>\n\n
