PerChat AI, the chatbot app powered by your own devices. Unlike other AI chatbot apps, all Characters, Chats, and data remains on your iPhone at all times and no data is shared. This app can run AI chats all on your iPhone if you wish, no internet required! It supports a wide range of iPhones, starting from the iPhone XS and up. 4GB of RAM is recommended but the more RAM you have, the better! If you happen to have a Mac or Windows PC lying around, you can have more complex and interesting chats by using that machine as a remote server for this app. Note that remote chatting is only supported on your own home network, or with the use of a VPN to access outside your home. You can run the PerChat AI server on your Mac or Windows PC with some hand-picked models, or you can run your own server such as LM Studio or Ollama, and have character chats using those tools. Features: - create richly detailed Characters to chat with, and Personas to chat with - partake in epic conversations with dungeon masters, real celebrities, or any character you can imagine - choose from a curated list of LLM models that will run well on your iPhone to change the flavor of your chats - run a vast number of LLMs on your own Mac or Windows PC to offload computing, and improve chat quality

Your NAS is packed with movies and TV shows. DSM Video is the app built to watch them — a fast, native experience on iPhone, iPad, and Apple TV. Synology dropped Video Station support on current DSM firmware. If you've kept your NAS up to date, you lost your video app. DSM Video fills that gap. It connects to DSVideoServer, a free lightweight package you install on your Synology, and gives you a fully native media player that feels like it belongs on your Apple devices. --- WHAT YOU GET Stream your personal library directly from your NAS — no third-party cloud, no subscription, no compression. Your files, your hardware, your control. - Native HLS Streaming — smooth playback on any network. Adaptive quality keeps video playing even on slower connections. - Apple TV App — a full tvOS experience built for the living room. Focus-engine navigation, cinematic poster art, and a parallax icon that looks great on your home screen. - iPad Sidebar — browse your entire library in a persistent sidebar while you watch. - Gesture Controls — swipe anywhere to scrub (a full swipe = 30 minutes). Swipe up or down to control volume. Pinch or double-tap to toggle fill and fit. - QuickConnect Support — access your NAS from anywhere using your Synology QuickConnect ID. No static IP, no port forwarding required. - Resume Anywhere — watch progress syncs across your devices. Stop on iPhone, pick up on Apple TV. - AirPlay — beam anything to any AirPlay-enabled display. --- COMPLETELY FREE. NO STRINGS. No subscription. No in-app purchases. No ads. You paid for your Synology — the app to use it should be free. DSM Video and DSVideoServer are both open-source on GitHub. --- WHAT YOU NEED - A Synology NAS running DSM 7.2 or later with an Intel or AMD (x86_64) processor - DSVideoServer installed from GitHub (free, open-source) - Your DSM username and password Setup takes about five minutes. Open Settings → How To for step-by-step instructions. --- DSM Video is an independent app and is not affiliated with Synology Inc.
