AI companion for your devices

Free

Your AI companion, your music, your money, your photos — four agents in your pocket, working together on one local engine and one shared memory, paired with your Mac. Your data stays on hardware you own. YINYUE — YOUR COMPANION Talk with Yinyue, the spirit companion of Linggen. She remembers you across conversations, plays your music, tidies your photos, and answers about your spending — right on the phone. Anything technical she hands to the agent on your Mac. DJ — YOUR MUSIC, EVERYWHERE Your library, synced from your Mac and kept for offline listening. Playlists, karaoke lyrics, and CarPlay with live lyrics in Now Playing. CFO — YOUR MONEY, PRIVATELY Transactions, budgets, and trends on the phone. Share a bank statement into the app and it lands in your books. No account linking — your statements never touch a server. SHIFU — YOUR PHONE'S KEEPER Storage health, photo cleanup, space to reclaim. Deletions always go through the system confirmation — nothing leaves without your say. PAIRED WITH YOUR MAC, NOT WITH A CLOUD Install Linggen on your Mac and scan one QR code. Phone and Mac then talk peer-to-peer over an encrypted channel on your network — music, photos, files, and memory sync with no server between your devices. The phone keeps working with the Mac asleep, and reaches Ling — the Mac-side agent — the moment it wakes. LOCAL-FIRST, OPEN AT THE ROOT Linggen means "spirit root" — the root system your agents grow from. The engine it runs on is open source. Your files, memory, and agents stay on hardware you own. Bring your own AI model: your existing ChatGPT subscription, a local model on your Mac, or an API key. The full guide lives at linggen.dev/guide.

Linggen Health. Your Apple Health readings, judged against your own normal, on your phone. A morning brief, a weekly plan with hands, a debrief minutes after a session, a Sunday letter, a page for your doctor. Yinyue speaks from the lock screen — one line when something changed, quiet otherwise. Memory kept per person, tidied nightly, synced with your Mac. The composer grows to five lines. Linggen Cloud now runs DeepSeek V4.1 Flash.
