Hey Product Hunt! 👋 I'm Aditya, the maker of LumiChats Offline.
I built this after realising something uncomfortable: every AI tool we use ChatGPT, Claude, Gemini sends every word you type to a server you don't control. For students studying sensitive topics, professionals working with confidential data, or anyone who simply values privacy, that's a real problem.
LumiChats Offline runs entirely on your machine. No internet after the first model download. No GPU needed. Your conversations never leave your device ever. And it's completely free and open source.
We've also released our own fine-tuned models on Hugging Face 4B, 7B, 11B Vision, a Coder model, and TTS — all free for anyone to use.
What would you want most from a private offline AI? Drop it below genuinely building this for you. 🙏
The fully offline part is honestly super cool. Feels way more private than most AI tools out there. Congrats!
Privacy-first AI is criminally undervalued right now. The framing about every typed word going to a server you don't control is the cleanest articulation of what makes cloud AI feel off, especially as data accumulates over years.
Building Fenly (AI translation extension) with a similar local-first stance on history. The thing I'd love to see in local AI: serious multilingual support that doesn't degrade to English-or-nothing at smaller model sizes. Translation work needs decent quality across language pairs, and most local LLMs trip on non-English performance below 7B parameters. Curious if your fine-tuned models hold up multilingually or are English-primary.
Strong launch. The OSS angle matters because users can verify the privacy claims, not just trust them.
Congrats on the launch. Clear direction: private, offline AI that actually works.
Hard to execute well. Curious how far you push it.
