A local AI chatbot that lives on your device and works even when you're offline.

Switched from ChatGPT to Atomic Chat 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 😂 Atomic Chat 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 💪 Atomic Chat 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.

Atomic Chat is a private AI assistant that runs entirely 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. Atomic Chat 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. Atomic Chat learns how you work and keeps your preferences across conversations.

Llama-3.2-3BAtomic Chat is free to run and will stay that way forever.

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.
Atomic Chat remembers your preferences and keeps them across every conversation. You can see what it remembers, edit anything, or wipe it all in one click.
