openLLM connects to OpenRouter and any OpenAI-compatible API — giving you access to dozens of frontier models in one clean, native Android experience.
Why openLLM
Stop juggling multiple apps and subscriptions. openLLM gives you a single, unified interface to talk to the world's best language models — with your own API key, on your terms.
Access GPT-5, Claude, Gemini, DeepSeek, and hundreds more through a single OpenRouter API key. Auto-select the best available model or pick your own.
Bring your own endpoint. Works with any server that speaks the OpenAI API format — local models, custom deployments, private APIs.
Change your active model mid-conversation with a single tap. Each chat remembers its model, so your context stays sharp.
All your conversations are saved and organized. Resume any chat, review past responses, or clear everything with one tap.
openLLM never proxies your requests. Your API key talks directly to your chosen provider — no middleman, no data collection.
Built for Android from the ground up. Fast, lightweight, and feels right at home on your phone — not a web app in disguise.
