Poly_Chat vs HALIO AI

This is a private, free, secure AI chat assistant powered by open-source models and Ollama. You can choose from a range of hosted models and explore their capabilities. It supports high-quality Markdown, web search, and document and image processing. All your data is stored locally on your device — never on external servers.

HALIO is a private, offline-first AI assistant that lives on your iPhone. No cloud. No account. No subscription. No signal required. Every major AI app today sends your conversations to a server. HALIO doesn't. The model runs on your device, your prompts stay on your device, and your history never leaves your phone. Airplane mode, a spotty connection, or no connection at all — HALIO keeps working. WHY HALIO • 100% on-device — GPU-accelerated for fast, efficient inference on modern iPhones. • Truly private — your conversations are stored locally and never transmitted. • No sign-up — open the app and start chatting. • No subscription — one-time download, no hidden tiers, no server-side rate limits. • Offline by default — works on a plane, on the subway, in the woods, under a desk. WHAT YOU CAN DO • Ask questions, brainstorm ideas, draft writing, summarize notes. • Dictate messages with on-device speech recognition. • Attach photos from your library to ground a conversation. • Keep multiple conversations going in parallel. • Use it as a thinking partner without worrying who's reading. FROM BUILDERBIAS HALIO is built by BuilderBias — intentional, transparent, responsible AI by design. We believe your AI should work for you, not the other way around. That means running on hardware you own, with data you control, under terms you can read. Download HALIO. Go offline. Keep thinking.
