About

Phantasm

Features
Read full description

Phantasm is a private AI chat client for the backend you already run. Point it at your own server: Ollama, vLLM, llama.cpp, or any OpenAI-compatible endpoint and chat with your own models over your own network. No account, no middleman, no data collection. YOUR SERVER, YOUR RULES • Connect with just a URL and a token — works against a bare Ollama out of the box • Add the open-source Phantasm orchestrator to unlock web search, image generation, and research modes • Multiple backend profiles for home network, VPN, or tunnel setups • Your token lives in the iOS Keychain; conversations are stored only on your phone A REAL CHAT EXPERIENCE • Fast streaming responses with markdown, syntax-highlighted code blocks with copy, and charts • Attach photos and files — vision models can see your images • Generated images appear inline; save or share them • Dictate messages with on-device transcription and have replies read aloud • Long generations survive backgrounding and pick up where they left off • Ask Phantasm from Siri and Shortcuts TOOLS ON YOUR TERMS • Per-chat toggles for web access and image generation • Optional device tools — location, calendar, Apple Health — are off by default and only shared with your own backend when you enable them • See the model's reasoning when a thinking model is selected PRIVATE BY DESIGN Phantasm operates no servers and collects no data. The app talks exclusively to the backend you configure — nothing else. What you say to your AI is between you and your hardware. Phantasm requires an OpenAI-compatible server that you provide (for example, Ollama running on your own machine). Feature availability depends on your backend's capabilities.
