Seaweeed vs Private AI Models

时光海苔是一款把“信息→载体→未来”串联起来的工具。你可以将一段文字、一个心愿或某个秘密，封存进图片、二维码或NFC标签中，辅以加密与时间设定，让它在某个不经意的时间点被再次想起、被再次读到。就像投向海里的漂流瓶，信息在时光与偶然中流动，被未来的你或陌生人发现。 主要功能： - 图片时间胶囊：把文字隐写进图片中，设定解锁时间或密码 - 二维码时间胶囊：将信息生成带时间/密钥的二维码 - NFC时间胶囊：把数据写入NFC标签，配合时间与密钥开启 - 漂流瓶模式：使用默认密码或开放密钥，让偶遇的人也能解锁 - 私密模式：自定义密码，仅信息持有者可解密 安全与隐私： - 本地处理：所有加解密均在本地完成，不上传到服务器 - 可控权限：仅在需要时请求相机/相册/NFC等权限 - 透明可控：你决定信息何时、向谁、以何种介质出现 适用场景： - 把给未来的信写进今天的图片里 - 与朋友之间的“时间约定”与纪念日 - 课堂/活动中的“盲投漂流瓶”互动 - 作品、展览中的叙事与彩蛋 “通过各介质的存储，辅以加密和时间判断，让数据通过双盲运送到未来。” 当你再次解锁那枚时间胶囊，读到的是过往的自己，也是此刻的真实。

Chat with an AI that lives on your phone, not in the cloud. Private AI is an offline AI chat app: open models like Qwen, Gemma and GLM run entirely on your phone — no server, no account, and after a one-time model download no internet at all. YOUR AI, YOUR DEVICE Cloud chatbots send every word you type to a data center. Private AI computes the answer on your phone's own chip: your chats, your photos and the models themselves stay with you. Uninstall it and everything goes with it. WORKS COMPLETELY OFFLINE Download a model once, then chat anywhere: • On flights, subways and trips abroad • In dead zones and on unreliable connections • Whenever you want answers that stay private Switch on airplane mode if you like — the app won't notice. THE LATEST OPEN MODELS, PHONE-SIZED • Qwen 3.5 (0.8B, 4B, 9B) — fast, smart and multilingual • Google Gemma 4 (E2B, E4B) — mobile-first quality, 140+ languages • GLM 4.6V Flash — flagship-class vision for high-end phones • Ministral 3 — compact, with a 256k context window • Bring your own: load any GGUF model by URL (Hugging Face links work) Models are 0.8–6 GB downloads. A "Fits your device" badge reads your phone's RAM so you know what will run well before you download, the catalog is searchable and filterable, and interrupted downloads resume where they stopped. BENCHMARK IT ON YOUR OWN PHONE Run the built-in benchmark on any downloaded model to see exactly how fast it loads and generates on your hardware — tokens per second, GPU or CPU — and pick the model that fits. CHAT WITH YOUR DOCUMENTS Attach a PDF, text or Markdown file to any chat and ask about it: the text is extracted and searched on your phone, the model answers from the matching passages and tells you which ones it used. Contracts, papers, manuals, notes: the files are never uploaded. UNDERSTANDS IMAGES Every model in the catalog supports vision. Add the optional image-support file, then snap a photo or pick one from your gallery: read documents, translate signs, decode menus, describe scenes. WATCH IT THINK Turn on thinking mode and reasoning models show their step-by-step working in a collapsible panel above the answer — great for math, code and anything worth double-checking. ASSISTANTS Start a chat with a ready-made assistant: Tutor, Writing Coach, Email Helper, Translator, Code Helper, Summarizer, Chef or Travel Planner, each with its own instructions and one-tap starters. An offline translator for your next trip, no signal needed. A REAL CHAT APP • Markdown that renders: code blocks with one-tap copy, tables and lists • Streaming answers with a live tokens-per-second readout • Switch models mid-conversation from the chat header • A system prompt per chat, plus Creative / Balanced / Precise / Thinking presets • Edit, regenerate, copy, select text — or have any answer read aloud (on-device TTS) • Search your chats, pin favorites, light and dark themes • Back up every chat and setting to a single JSON file, and restore anywhere PRIVATE BY DESIGN • Conversations and photos are processed on your device, never in the cloud • No account, no sign-up, no server • GPU-accelerated by llama.cpp — Metal on iPhone, OpenCL on Snapdragon Adreno PRIVATE AI PRO Free to use, with ads that never interrupt an answer (offline, none load).
