Made an on-device AI companion app: unfiltered, and your chats never leave the phone
I've been building Xin, an AI companion / roleplay app where the model runs locally on your device instead of on someone else's server.
Why: every companion app I tried had the same two problems. A filter that breaks immersion mid-scene, and the fact that your most personal conversations are sitting in a company's database — one policy change away from being deleted, changed, or read.
Running on-device addresses both at once:
- Unfiltered no server-side moderation layer between you and the model
- Private by architecture — chats can't be read by a company, because there's no server to send them to
- Persistent memory — your companion remembers you across sessions, stored locally
- Works offline after the initial model download
- Hundreds of characters (realistic and anime styles), or build your own
Free to use; there's a VIP tier, but the core app works without it. 18+ only.
Happy to answer anything about how it works — the on-device inference was the hard part.
