Room 03 · AI companion pendant · Friend Global, Inc.
Friend,rebuilt.
An always-listening AI companion worn as a pendant. It hears your day, and the current version answers out loud through a speaker.
The goal
A pendant about 2 inches across that listens all day, sends speech to a phone over Bluetooth, and answers through its own speaker.
What is known.
Read on October 6, 2026. Every line says how it is known and where it comes from.
- Maker
- Stated by the maker on its own product page or manual.
- Reported
- Reported by the press or by a community project, not by the maker.
Not published.
What nobody has said in public yet. Each one is a question the room answers by building.
- The processor, the radio chip and the battery's capacity.
- The microphone and the speaker parts, and how the speaker's cavity is sealed.
- The pendant's thickness.
- Any certification filing or teardown. None was found under the maker's name.
Six milestones.
In order. Each one is reached when its last line is true of the board.
- 01
Power.
USB-C charging for a small LiPo, sized for 18 to 24 hours with the mic always on.
Done whenA full charge in about 30 minutes, and a measured day of listening.
- 02
Radio.
A Bluetooth LE SoC that streams compressed speech to a phone and plays the reply back.
Done whenA sentence goes to a phone and its answer comes back out loud.
- 03
Listening.
One or two PDM microphones behind an acoustic port.
Done whenSpeech at arm's length is captured cleanly through the shell.
- 04
Speaking.
A class-D amplifier and a micro-speaker in a sealed back cavity.
Done whenA reply is intelligible at arm's length.
- 05
Touch and light.
A capacitive tap, a haptic motor and RGB light under a diffuser.
Done whenA tap buzzes and the light answers it.
- 06
Pendant.
A 2 in disc with a bail for the necklace, a speaker grille and splash sealing, built in the Product view.
Done whenThe board, cell and speaker fit, and the packaging check is clean.
Room rules.
For everyone on the board. The board is shared, so most of them are about the others.
- Recording consentThis room
- A device that listens all day records other people. Test on yourselves, and follow the recording law where you are.
- One board
- Everyone builds the same project. Don't duplicate it to work alone; work here, where the others can see it.
- Your own thread
- Talk to Inky in a chat thread of your own. A new message in a thread can stop the turn already running there.
- One long job at a time
- An autoroute or a long Inky turn holds the board. Tell the others before you start one.
- Undo is shared
- The board has one history for everyone. Pressing undo twice takes back a teammate's last edit, so look before you press.
- Inky runs on your account
- The board is shared; your usage is not. Each person's Inky turns count against their own plan.
- Public information only
- Work from what the maker published, regulatory filings and open references. No leaked documents, no copied firmware, no logos.
- The case needs a paid plan
- Every room's last milestone is built in the Product view, which comes with every paid plan and not with the trial. Members on the trial can do every other milestone.
Start from.
Open work that gets the room past a blank board. Check each licence before copying from it.
