Edge Mind Ai
Read full descriptionHide full description
Edge Mind Ai is a privacy-first AI assistant that runs entirely on your iPhone and iPad. Your conversations, prompts, and photos never leave your device — all AI inference happens locally on Apple Silicon. There is no cloud server, no account required, and no data collection. RUN 20+ MODELS, LOCALLY Choose from a curated catalog of 21 open models from Apple Intelligence, Google Gemma, IBM Granite, Meta Llama, Microsoft Phi, DeepSeek, Mistral, Qwen, SmolLM, and Liquid AI. Switch between them mid-conversation. Download only the ones you want; delete them anytime to reclaim space. REAL CHAT, NOT A WRAPPER • Token-by-token streaming responses • Full Markdown rendering with code blocks and syntax highlighting • Multiple conversations — create, rename, and resume sessions from History • Attach a photo from your camera or library and ask a vision model about it • Voice dictation — speak your prompt; responses read back via on-device speech PRIVACY IS THE DEFAULT • Fully offline out of the box. Nothing is uploaded unless you turn on Live Search. • No telemetry, no analytics, no cloud sync, no login required. • A guest profile gets you chatting in one tap. • Optional Face ID / Touch ID / local credentials to protect your space. • Your HuggingFace token (for gated model downloads) is stored in the iOS Keychain. OPTIMIZED FOR YOUR DEVICE Edge Mind Ai detects your chip and tunes itself automatically — context windows of 2K–8K tokens and flash-attention acceleration on supported devices, so large models run within your iPhone's memory without crashing. OPTIONAL LIVE WEB SEARCH Turn on web grounding per prompt when you need fresh information. Bring your own key for Tavily, Brave Search, Serper (Google), or a self-hosted gateway. Search results come back with inline source citations. It's off by default — your AI stays local unless you ask it to look something up. CURATED, NOT THE WILD WEST The model catalog is hand-picked and capability-audited for this app's runtime. Thinking models stream a reasoning lane; vision models accept images; tool-calling models can trigger web search. Badges reflect what the app actually supports, not just marketing claims. WHO IT'S FOR • Privacy-conscious users who want private AI assistance without sending data to a server • Developers and researchers experimenting with local LLMs on iOS • Anyone who needs an AI assistant that works on a plane, underground, or offline • People who want to own their AI — models live on your device, under your control REQUIRES iPhone or iPad with iOS 17 or later and an A14 chip or newer for best results. MLX models run on physical Apple Silicon only (not the simulator). Apple Intelligence model requires a compatible device. Edge Mind Ai is an independent project. It is not affiliated with or endorsed by Apple, Google, Meta, Microsoft, IBM, Alibaba, Mistral, Hugging Face, or Liquid AI. Model weights are the property of their respective creators and are loaded under their original licenses.
Stacks

Everything you save online ends up scattered — a restaurant buried in your Instagram saves, a recipe in a TikTok favourite, a hotel in a Safari tab you'll never find again. Stacks brings all of it into one place and organizes it for you. Share a link to Stacks from any app and it reads the page, works out what it is, and files it away: the restaurant into Food, the hotel into Travel, the outfit into Fashion — with a title, a summary, tags and a cover image, ready to find months later. SAVE FROM ANYWHERE • Share from Instagram, TikTok, Pinterest, Reddit, YouTube, X, Facebook or Safari — anything with a share sheet • Or paste a link straight into the app • Shared links are imported and organized in the background, before you next open the app ORGANIZED FOR YOU • Every save is categorized automatically — Food, Travel, Fashion, Fitness, Shopping, Learning and more • Tags, topics, summaries, places, brands and recipes pulled out of the page for you • Smart collections group related saves into a trip, a reservation, a concert, a birthday • Or build your own collections by hand FIND IT BY MEANING • Search understands what you meant, not just the words you typed • "Sushi in Tokyo" or "black outfit" surfaces the right save, even when those exact words aren't in it • Filter by category, platform, tag or collection MORE THAN A BOOKMARK • Map — every saved place on one map, exactly what you want before a trip • Calendar — put a save on a date and get a reminder when it matters • Notes and checklists on any save, for packing, shopping and planning • Favourites and an archive to keep the list clean PRIVATE BY DESIGN • No account. Nothing to sign up for • On iPhones with Apple Intelligence, saves are analyzed by Apple's on-device model; on every other iPhone an on-device fallback does the same job • Search runs on-device too — no query ever leaves your iPhone • No analytics, no ads, no tracking, no third-party SDKs, and no servers of ours for anything to be sent to Free, with no subscription and no in-app purchases.
