Pinneds: your stuff, pinned together. A shared board where friends' photos of their real things become cut-out pins, and anyone remixes everyone's pins into one new picture that credits whose things are in it. The problem. Group chats hold the pieces of our lives but they are a dead end for making anything together. There is no effortless way for friends, families, or teams to pull real things out of separate photos and arrange them into one picture. Pinneds turns everyone's camera roll into a shared studio: one link opens a board where real things become pins, and anyone can pick, combine, and direct them into new compositions while every contributor keeps credit and control over their own things. No app, no sign-up: the link is the invitation. How it works. (1) Start a board, send the link. (2) Anyone adds a photo: Muse Spark names the things in it, SAM 3.1 cuts each one out, and every cut-out lands on the board as a pin with its owner's name. Missed something? Tap it. (3) Pick 1–4 pins from anyone, then type an idea, tap one Muse Spark suggests, or say it aloud (Muse Voice Transcribe), and Muse Image composes a new scene "Made from" the people whose things are in it. (4) Remix any scene with new pins; the credits carry forward. What the models make possible. Naming and cutting take seconds and are only the start. The product is what happens next: real things from different people's worlds meet in one picture. The models do their work in the first seconds; the shared board is what the group keeps. Built to hand to family. Original photos are never stored (an EXIF-stripped working copy, deleted when you pin). People in photos are allowed; a detected face gets a one-line consent note. Every model call runs through one gateway with a fail-closed daily budget, and a provider refusal returns a friendly line. Seven UI languages. Control stays with the owner. You can rename or delete your pins at any time, and deleting a pin hides every scene that used it, including other people's remixes. Anyone on a board, invited or visiting, can report it without an account; confirmed reports are removed within 24 hours. Try it: https://pinneds.com.

Built Oct 26 – Nov 4, 2026 by one developer steering coding agents, one Linear issue per pull request: 240 merged PRs and 2,091 automated tests as of Nov 4, with Cursor Bugbot reviewing every PR. Meta's Muse Code set up Firebase and App Hosting, wired in the Meta models, built the Studio core overnight (29 PRs, on Muse Wonder Full) and the Stripe billing; Claude Code rebuilt the UI, added the languages, refined the billing, and carried the app to production.
