Nemos is an independent native client for Memos-compatible servers. It helps you capture ideas, organize notes, manage attachments, and switch between local mode and your own remote server. Key features: - Create, edit, and manage memos - Markdown editing and preview - Image, audio, and document attachments - Browse public content from the server you connect to - Local mode with iCloud sync - Remote mode for user-provided Memos-compatible servers - Local data export, cache cleanup, and privacy controls Data modes: Nemos supports both local mode and remote mode. Local mode stores content on your device and can sync through your own iCloud account. Remote mode requires you to provide a Memos-compatible server URL and access credentials. Third-party disclosure: Nemos is independently developed. It is not the official Memos app and is not affiliated with or endorsed by the Memos project. Nemos does not operate, host, or moderate the remote servers users connect to.
Phantasm

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 β’ Connect with just a URL and a token β works against a bare Ollama out of the box β’ Add the open-source Phantasm orchestrator to unlock web search, image generation, and research modes β’ Multiple backend profiles for home network, VPN, or tunnel setups β’ Your token lives in the iOS Keychain; conversations are stored only on your phone A REAL CHAT EXPERIENCE β’ Fast streaming responses with markdown, syntax-highlighted code blocks with copy, and charts β’ Attach photos and files β vision models can see your images β’ Generated images appear inline; save or share them β’ Dictate messages with on-device transcription and have replies read aloud β’ Long generations survive backgrounding and pick up where they left off β’ Ask Phantasm from Siri and Shortcuts TOOLS ON YOUR TERMS β’ Per-chat toggles for web access and image generation β’ Optional device tools β location, calendar, Apple Health β are off by default and only shared with your own backend when you enable them β’ 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 β 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.
