teemoon vs Phantasm

teemoon is a private AI chat app. there is no teemoon server. your phone talks directly to the model you pick. run a model on the phone, connect a computer you own, or paste a cloud API key. keys live in the iOS Keychain. chats stay on the device — SwiftData, no iCloud. • no account. no subscription. no analytics. • Gemma 4 on the phone via LiteRT. no key, works offline. • a computer you own is first-class: llama.cpp, ollama, lm studio, or any OpenAI-compatible server. • bring-your-own-key for near.ai, OpenRouter, NVIDIA, Grok, Fireworks, and other OpenAI-compatible providers. an Anthropic key does not work. • end-to-end encryption is near.ai's own TEE fleet only. every other cloud provider is TLS. the app says so on the row. requires iOS 18.6 or later. fully open source under AGPL-3.0 — the whole client is at github.com/teemoonai/teemoon-ios.

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.
