Overview
LocoStudio is a privacy-first desktop application that lets users chat with multiple AI models either locally on their computer or by connecting to cloud providers with the user’s own API keys. It emphasizes offline capability so sensitive documents (PDFs, images, YouTube transcripts, websites) can be analyzed without sending data to third parties. Users can run local models, compare models side-by-side, and switch between providers (e.g., ChatGPT, Claude, Gemini) within one unified UI. The product offers easy setup guidance for local models, keyboard shortcuts, UI themes, and a lightweight, subscription-free pricing approach where users can opt for a one-time purchase to unlock premium features.
