DDchat AI vs 返航

DDchat AI is a polished, minimalist native iOS AI client with web search, multimodal understanding, and HTML rendering. Connect your own APIs to use different providers and models in one flexible, fluid app. — BEAUTIFUL BY DESIGN — From rounded bubbles to smooth streaming animations, from live scrolling reasoning previews to syntax-highlighted code blocks, every pixel is polished. Full Light and Dark Mode support, liquid glass, and gradient accents create a truly native experience. — OFFICIAL APIs AND THIRD-PARTY GATEWAYS — One app to connect with advanced AI models from around the world. Use DeepSeek, Kimi, MiniMax, Zhipu, MiMo, Qwen, and more. Connect to official providers or compatible third-party gateways, choose your provider, and switch models to suit each task. — AUTOMATIC MODEL CAPABILITY DETECTION — A built-in capability database detects whether a model supports advanced reasoning, vision, tool calling, and more, then applies the appropriate parameters. The database updates silently from the cloud, helping new models work without an app update. — HTML RENDERING ENGINE — HTML tags in AI replies can be rendered directly in the conversation, making cards, tables, lists, and other rich content easier to read. Built-in Markdown parsing and syntax highlighting for 10+ languages, including Python, Swift, Go, and Rust, keep code and quotes clear as well. — MATH AND DIAGRAM RENDERING — Render LaTeX equations and Mermaid diagrams right in your conversations, from formulas to flowcharts and sequence diagrams. Zoom in on diagrams and save them as images for study, organization, or sharing. — WEB SEARCH WITH SOURCES — Use built-in model search or connect a range of independent search services. Models can search and browse the web based on your question, with citations and sources shown directly in the answer so important information is easy to verify. — MULTIMODAL IMAGE UNDERSTANDING — Take a photo or select multiple images from your library and chat directly with vision-capable models. Analyze screenshots, understand scenes, or read text from images with ease. — VISUALIZED REASONING — See a model's reasoning as it is generated, then expand it for more detail. When supported, choose different reasoning levels to balance response speed and depth. — TASK-SPECIFIC ASSISTANTS — Create dedicated AI assistants for different scenarios, such as translation, coding, writing, or research. Each assistant has its own system prompt, sampling parameters, context length, and default model. — ASSISTANT CREATION AND OPTIMIZATION TOOLS — Describe what you need in one sentence, and AI can create a new assistant for you. If the results are not quite right, use another request to refine its prompts and related settings so it works the way you want. — PRIVACY-FIRST, STORED LOCALLY — API keys, chats, and assistant settings are stored locally on your device. Requests go directly to the AI provider you choose, without passing through a DDchat intermediary server. No analytics, no ads, no tracking. — MORE HIGHLIGHTS — - Multi-conversation history grouped by assistant - Fetch model lists online or add models manually - Duplicate, import, and share assistants - Keep streaming replies running in the background and generate with multiple assistants at once Getting started: 1. Add an API provider in Settings, either an official endpoint or a compatible gateway 2. Create an AI assistant and configure its prompt and parameters 3. Choose a model and start chatting Note: This app requires you to provide your own API keys. It does not include or provide any AI service. — CONTACT — For feedback or questions, please email: ddchatsupport@gmail.com

你不是没有答案。你只是每次到了最难的时候，又忘了。 返航是一款私人信标库。它把你曾经想明白的话、值得保留的解法和每次新的理解，整理成可以反复回看的信标。 当你迷茫、拖延、比较、焦虑，或再次困在同一个问题里，只要写下或说出此刻发生的事，返航会从你的信标与公共解法库中寻找真正相关的内容。默认匹配在设备上完成；你也可以明确选择启用 DeepSeek 语义匹配。没有合适答案时，不会用随机结果敷衍你。 你可以： - 用文字、语音或粘贴内容描述此刻的困境 - 左右滑动浏览自己的信标卡 - 按场景发现新的解法并收藏到个人信标库 - 收藏、编辑、删除或复制完整信标为 Markdown - 在每次返航后写下新的理解 - 回看同一信标下不断变化的返航记录 - 用小组件每天看见一条重要提醒 私人信标和返航记录默认保存在设备本地。DeepSeek 完全可选：只有你在 App 内看到完整的数据说明并明确允许后，返航才会发送当前输入和完成该次 AI 功能所需的候选内容。拒绝后仍可使用本地关键词匹配，并可随时在设置中撤回许可。 返航不是替你做决定。它只是让过去清醒的自己，在你最需要的时候，再次出现。 Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
