AgentChat

Your AI, your rules. AgentChat connects your phone to powerful AI models running on your own computer or via cloud APIs. Your conversations never leave your device. -*- Truly Private Every message stays on your phone. Connect to a model on your own hardware and nothing touches the cloud. No accounts, no tracking, no data collection. -*- Multiple AI Providers • LM Studio — Run open-source models locally on your PC/Mac • DeepSeek — Fast, affordable reasoning models via API • OpenAI — GPT-4o, GPT-4, and compatible services (Groq, Together AI) • Generic — Any server that speaks the OpenAI API format -*- Voice Input Tap the microphone and speak. A live recording overlay shows your words as you say them, with animated waveform feedback. When you stop talking, the text lands in your message box ready to send. -*- Custom Agents Create specialised AI personas with their own instructions, model preferences, and tool permissions. Built-in agents for general chat, photo analysis, and step-by-step problem solving. Your custom agents' instructions can be protected from extraction. -*- Online Tools When connected to a tool-capable model, the AI can search the web, check the weather, convert currencies, and do calculations — all through free public services that don't touch your server. -*- Vision Attach a photo and ask about it. Models with vision capabilities can describe images, read text from photos, analyse charts, and spot details you might miss. -*- Thinking Modes Choose how hard the model thinks: Off (fastest), Balanced, or Deep (most thorough). Works with every model that supports reasoning. -*- AMOLED Black Theme Three appearance modes: Light, Dark, and true AMOLED black that saves battery on OLED screens. Or let the app follow your phone's setting. -*- Chat History Conversations are saved locally with full search. Export any chat to share it. When a conversation gets long, summarise it and continue in a fresh chat without losing context. Switch between providers without losing your settings. Each provider's credentials are saved independently. -*- Security • API tokens stored in Android's secure keychain • Cloudflare Access support for remote servers behind a tunnel • No hardcoded credentials in the app • Optional instruction protection prevents AI prompt extraction -*- Connection Methods • Local Wi-Fi — Same network, fastest response • Tailscale — Private VPN, works from anywhere, free • Cloudflare Tunnel — Public HTTPS with access control • Cloud API — Direct to DeepSeek, OpenAI, Groq, Together AI -*- Open source. No subscriptions. No ads. Just AI that works for you.-*-
