LocalChat — Private AI That Runs Entirely on Your Mac

LocalChat is a local-first desktop AI application for macOS that lets you chat with over 300 open-source AI models — completely offline, with zero data collection, and no account required. Built natively for Apple Silicon (M1–M5), LocalChat delivers fast, private AI conversations without ever sending a single byte of data to the cloud. Pay once, own it forever — no subscriptions, no recurring fees.

The Problem with Cloud AI

Every conversation you have with cloud-based AI services like ChatGPT, Claude, or Gemini gets logged on corporate servers and may be used as training data. Your sensitive questions, creative ideas, confidential business discussions, and personal thoughts are stored on infrastructure you don't control. This makes cloud AI unsuitable for legal work, confidential business matters, medical questions, or anything you wouldn't post publicly. On top of that, subscription-based pricing means you're paying $20/month — $240/year — to rent access that disappears the moment you stop paying.

LocalChat eliminates these concerns entirely. Everything runs on your Mac. Your conversations are stored locally and encrypted at rest. There are no cloud servers, no telemetry, no tracking, and no data shared with third parties — ever.

Core Features

Complete Local Processing

All AI inference happens on your device. LocalChat leverages your Mac's Apple Silicon hardware (M1, M2, M3, M4 and M5 chips) for fast token generation that rivals cloud API speeds. Once you've downloaded a model, no internet connection is required. Use LocalChat on flights, in remote areas, or anywhere without WiFi.

300+ Open-Source AI Models

Access models from leading AI providers including Meta's Llama, Mistral AI, Google's Gemma, Alibaba's Qwen, and DeepSeek. All models run in GGUF format and can be switched instantly based on your needs. Whether you need a lightweight model for quick tasks or a large model for complex reasoning, LocalChat has you covered.

One-Click Model Manager

Browse and download thousands of GGUF models with a single click. The built-in model manager handles downloading, storage, and updates — no command-line knowledge required.

Chat with Documents

Drag and drop PDFs, text files, or entire codebases into your conversation. LocalChat indexes documents locally and answers questions based on your content. Analyze charts, review contracts, summarize research papers — all without your files ever leaving your machine.

Vision Capabilities

Supported models can analyze images, charts, and screenshots. Drop in a chart and ask for a description, share a UI screenshot for feedback, or have the AI read text from images — all processed locally on your hardware.

No Account Required

Download LocalChat and start chatting immediately. There's no sign-up flow, no login screen, no email required. You own your data completely from the first interaction.

End-to-End Privacy

Zero cloud servers. Zero data collection. Zero tracking. Conversations are stored locally on your Mac and encrypted at rest. No telemetry is collected — ever. 100% of messages are processed on your device, and exactly zero data is shared with third parties.
