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 (BYOK) for near.ai, OpenRouter, NVIDIA, Grok, Fireworks, or any OpenAI-compatible provider. that reaches Claude, GPT and Gemini, and open models like GLM, DeepSeek, Qwen and Kimi. • 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. • web search as a tool, through Brave, with the sources beside the reply. requires iOS 18.6 or later. fully open source under AGPL-3.0 — the whole client is at github.com/teemoonai/teemoon-ios.
