Endemic: Local On-Device AI

Endemic runs large language models on your iPhone, iPad, and Mac. No API keys. No cloud. No subscription. The model lives on your device and so do your conversations.

Download a model from the curated catalog, then chat offline from that point on. The catalog filters by your device's RAM so you only see models that actually fit your hardware.

Ships with the latest open source models in sizes from 0.8B (any recent iPhone) to 9B (Mac and iPad Pro with 16GB+). More model families coming.

WHAT LOCAL INFERENCE ACTUALLY MEANS

The model runs on your CPU and GPU. No request leaves your device during a conversation. This is not "private cloud" or "encrypted API calls." The computation happens on the hardware in your hand.

The tradeoff is real: a 4B model on a phone produces useful results for many tasks, but it will not match a frontier model on datacenter hardware. If you need the best possible responses, cloud AI is the answer. If you want a model you own on a device you own, this is it.

MODELS AND DEVICES

Endemic detects your hardware and recommends the strongest model that fits. An iPhone with 8GB runs the 4B comfortably. iPads and Macs with 16GB+ handle the 9B. The 0.8B fits anything and responds fast.

Models are open-weight GGUF files downloaded from public hosting. One download, stored locally, excluded from iCloud backup so it does not eat your storage quota.

PRIVACY

There is no Folding Sky backend. No analytics on your conversations. Conversations sync through your personal iCloud if you want, and nowhere else.

Free app. Open-weight models. Built by one person in Beaverton, Oregon.
