A private AI chatbot that runs LLMs locally on your Mac — no account, no cloud, no limits. A free ChatGPT alternative that works offline.

Switched from ChatGPT to local AI last week. Running Llama 3 locally and honestly the speed is insane 🔥 Plus zero monthly cost. Why did I wait so long?
My client data never leaves my machine 🔒 If you're in legal or healthcare — this is it.
Finally a local AI app that doesn't look like a terminal from 1995 😂 This local AI app's UI is genuinely beautiful. And the model download experience is 👨🍳💋
I used to pay $20/mo for GPT-4. Now I run Mistral locally on my M2 Mac and it handles everything I need 💪 Running a local LLM made the switch painless.
The memory feature is a game changer 🧠 It remembers my coding preferences across sessions. Feels like it actually knows how I work now. I asked it to always use TypeScript and Tailwind — next session it just did it without me saying anything. This is how AI tools should work.
Open source AND beautiful UI? ⭐ Take my star.
Tried every local LLM app out there. Atomic Chat is the only one my non-technical wife can actually use 😄 One-click model download is brilliant.

A private AI assistant that runs LLMs locally on your device. Chat with 1,000+ open-source models, analyze images, connect your favorite apps — all without sending a single byte to the cloud.
Choose from thousands of open-source models on Hugging Face — or bring your own. Llama, Mistral, Gemma, DeepSeek, Qwen and more.
















Drop in a screenshot, a photo, or a diagram. Your local AI reads and explains what it sees — all processed on your machine.



Gmail, Slack, Telegram, Figma, Trello — Atomic Chat plugs into the apps you already use. Ask it to send a message, check your calendar, or create a task.

No need to re-explain yourself every session. Your local AI learns how you work and keeps your preferences across conversations.

Llama-3.2-3BA private AI chatbot you can run offline — free forever, no subscriptions or token limits.

Everything you type stays on your Mac — you're running your own local LLM on your own hardware. No server on the other end, no analytics watching what you ask about.
Because everything runs locally, there's simply no infrastructure between you and your AI that could leak, get breached, or be accessed by someone else.
The entire model weights are downloaded once, so you get the full AI chat power running locally on your device — no internet connection needed.
Your local AI remembers your preferences and keeps them across every conversation. You can see what it remembers, edit anything, or wipe it all in one click.

Applications



Your conversations stay yours. Prompts never leave your Mac — no cloud, no servers, no data collection. Just you and your AI.
Works without internet. On a subway, in a plane, or behind a firewall — your AI answers on demand, wherever you are.
“We believe AI should be open and private — not locked behind a $20/month paywall. This local LLM app is an easy way for anyone to run AI locally on their own hardware, completely free, without subscriptions, or token limits.”

Atomic Chat is a free, open-source macOS application that runs large language models entirely on your Mac. Atomic Chat gives you a ChatGPT-like experience without sending any data to external servers — everything is processed locally using your own hardware.
Atomic Chat is designed for developers, writers, researchers, students, and anyone who wants to use AI without subscriptions or privacy trade-offs. If you own a Mac with Apple Silicon, Atomic Chat lets you run capable language models at no cost.
Yes. Once you download a model, Atomic Chat runs completely offline. You can use Atomic Chat on a plane, in a subway, or behind a corporate firewall — no internet connection is required for conversations.
Atomic Chat supports popular open-source models such as Llama, Mistral, Gemma, and DeepSeek. You can download and switch between multiple models directly from Atomic Chat, choosing the one that best fits your task and hardware.
Completely. Every prompt and response stays on your Mac. Atomic Chat has no cloud component, no telemetry, and no data collection. Your conversations are never sent anywhere — they exist only on your device.
Yes. Atomic Chat is free to download and use with no subscriptions, token limits, or hidden fees. Atomic Chat is open source under a permissive license, so you can inspect the code, contribute, or fork it.
Atomic Chat runs on any Mac with Apple Silicon (M1 or later) and at least 8 GB of RAM. Models range in size, so you can pick lighter ones for older hardware or larger, more capable ones if you have an M2 Pro, M3 Max, or similar chip.
Cloud-based AI services offer the most powerful models but require a subscription and send your data to remote servers. Atomic Chat trades some raw capability for complete privacy, zero cost, and offline access — making Atomic Chat ideal for everyday tasks, drafting, brainstorming, and code assistance.
