Bring your models, your data and your privacy — and talk to them from a beautiful iPhone and Mac app. WHAT YOU GET • Native chat with live streaming, full Markdown, tables and code — never a wrapped web page. • Connect any model: OpenRouter, Ollama, local llama.cpp, and other compatible endpoints. • A real AI workspace, not just a chatbot: notes, calendar, a built-in email client (IMAP/SMTP), personal documents (RAG) and image generation. • 68 built-in agent tools — code, web search, documents, multi-agent, email and calendar. • Compare two models side by side, and run Deep Research with a native report view. MAKE IT YOURS • 34 languages, including right-to-left (Arabic, Persian, Urdu, Pashto). Auto-detects your device language. • 16 themes, custom fonts and animated backgrounds. PRIVACY FIRST • It's YOUR server. Odysseus only talks to the address you configure — nothing is sent to us. • On-device voice (speech-to-text and text-to-speech). • Optional Face ID / Touch ID app lock. Note: Odysseus is a client for a self-hosted Open WebUI / Odysseus server. You need your own server to sign in.

Verdict
The clearest difference is price: Sentence Embedding at Free against Odysseus's $2.99. Sentence Embedding also leads on iOS requirement (15.8.3 vs 17.0). Odysseus's advantage is ads (none vs shown) and update cadence (every 6 days vs fortnightly). On in-app purchases and device support there is nothing between them.
