BastionChat: Your AI, your data, your device - no cloud required

Hey Product Hunt! 👋 Excited to share BastionChat with this amazing community! Why I built this: I was frustrated that every AI conversation required sending my data to someone else's servers. Whether it's work documents, personal thoughts, or sensitive info - it all goes to the cloud. So I spent months figuring out how to run proper AI models (Qwen3, Gemma3) locally on mobile devices. Not dumbed-down versions - the real deal with voice, document analysis, and RAG capabilities. What makes me proud: Your conversations truly stay private (works in airplane mode!) No per-token costs or subscription surprises Chat with PDFs without uploading them anywhere Voice mode that works completely offline Perfect for: Anyone handling sensitive data, frequent travelers, privacy advocates, or folks who just want AI without the surveillance. I'd love your feedback! What would you use truly private, local AI for? Also happy to answer any technical questions about running modern LLMs on mobile 🤓 Thanks for checking it out!
