Local Keep AI is a local-first AI workspace. Chat with hundreds of models, talk to it out loud, and get back real files you can open — not descriptions of files. WORKS OFFLINE Local models run on your device. Your conversations stay on your device, and your usage keeps counting correctly whether or not you have a connection, syncing when you reconnect. REAL FILES, NOT DESCRIPTIONS Ask for a PDF, spreadsheet, CSV, document, presentation, image, audio clip or video and Local Keep AI produces the actual file. Ask a plain question and you get a plain answer — it does not attach a file to everything. HUNDREDS OF MODELS Local GGUF models, Ollama models, hosted models and OpenRouter's catalogue, all in one picker with filters for what each one can actually do: code, reasoning, vision, image, audio, video and document generation. OpenRouter's free models work with no key of your own; its paid models need your own OpenRouter key, and are billed to your account rather than bundled into a plan. TALK TO IT Speak instead of typing. Local Keep AI transcribes your voice, runs it through the model you chose, and reads the answer back. Choose the voice and language it replies in, from the voices installed on your device. EVERYWHERE YOU WORK The same account works on iPhone, iPad, Mac, the web and desktop, plus a command-line tool for your own machine. PLANS Free, with no card and no trial clock. On the Free plan you can chat with the free models, generate images, and run models on your own device. It does not expire and it is not a trial, because none of it costs us anything to serve. Paid plans add Local Keep AI's own hosted models, the command-line tool and the SMS bridge, each with a monthly output-token allowance: Starter 300,000 tokens for $19.99 per month, Pro 2,000,000 for $49.99, Premium 10,000,000 for $99.99, Ultra 30,000,000 for $199.99. Annual plans bill ten months for twelve. Extra tokens are bought before they are used, so you are never billed after the fact and can never run up a bill by accident. Paid models from other providers work with your own OpenRouter key, billed to your account, not ours.
