Russet: OpenRouter & Local AI

Russet runs AI models on your phone, so your chats stay on your phone.

Most AI apps are a window onto someone else's computer. Everything you type goes to a server you'll never see, and you just hope it's treated well. Russet works the other way around. It runs Google's Gemma models on the phone itself, downloaded once and usable after that with no connection at all. Russet looks at how much memory your phone has and recommends the model that will run well on it. When you need something bigger, you can add your own OpenAI or OpenRouter key. Either way, your chat history lives on your device and nowhere else. It isn't included in cloud backups.

Russet can also do something most AI apps can't: ask two models the same question at once. Put two cloud models in a group chat and each one answers without seeing the other's reply. Send a message to both, or to just one. When both have answered, tap Consolidate. A third model, which can be either of the two or any other, reads both answers and writes one. It keeps what's right in each, says where they agree, and where they differ, says which one is better supported. Two models that disagree tell you more than one model that sounds sure.

• Group chats. Two models, one question, two independent answers. Each model keeps its own history of the chat.
• Consolidate. Turn two answers into one that shows where they agree and where they don't. It works on any earlier turn too.
• On-device models. Gemma runs locally and offline, and the larger Gemma models can read images too.
• Private by default. Nothing you type leaves your phone unless you pick a cloud model.
• Incognito. Chats that are never saved.
• Web tools. OpenRouter models can search the web, read pages, and check the time where you are.
• Flow. Paste in some text and summarize it, translate it, rewrite it, label it, or have it argue the other side.
• Projects. Keep related chats and files together. A file only goes to a cloud provider if you turn that on for that file.
• Personas. A writing coach, a study buddy, a devil's advocate, or just a good listener.
• Move your chats. Russet also runs on iPhone, Mac, and Linux, and an encrypted transfer file carries a chat between any of them.
