AI-IDE is a lightweight editor for iPhone, iPad, and Mac. Edit Markdown, code, and config files inside iCloud Drive or any Files folder — and work with the LLM of your choice without leaving the document. KEY FEATURES • Mark up the preview, let AI edit — Tap a spot or select a passage and say what to change. Queue marks, send one batch, review one diff. • Bring your own AI — Anthropic, Gemini, DeepSeek, OpenRouter, Groq, Mistral, any API-compatible endpoint, local Ollama, or an AISA key for 70+ models. 16 one-tap presets. No built-in account or key: nothing runs until you add one. • You approve every change — Edits show a diff first; nothing is written until you tap Apply, and overwrites are snapshotted. • Multi-tab editor — Syntax highlighting for 10 languages, line numbers, autosave, find & replace. • Rich Markdown preview — Outline navigation, in-document search, reading progress with resume, code copy, task checkboxes, light/dark themes. • Office files and PDFs, both ways — Export to PDF, Word, Excel, and PowerPoint on device; "AI Refine" turns a document into slides, using your own .pptx as the master and Brand Kits for colours, fonts, and logo. Open a .docx, .xlsx, .pptx, or PDF to edit in place, formatting kept. • AI illustrations — One prompt draws an illustration at the cursor with your own image model; it flows into PDF, Word, and PowerPoint. Decks can auto-illustrate. • Built-in data tools — 35 the AI calls itself: web pages, academic papers, US financials and SEC filings, crypto prices, X posts, prediction markets, Perplexity. Switched on by category, with the token cost shown. HTTPS-only and host-whitelisted; your key is injected on device, never seen by the model. • Prompt Library — Activate several presets at once, merged in your order with a size meter. Three research procedures are built in; add more from the library or GitHub. • KB Library — File a document once and reference it as often as you like: type ~ to attach one, or let the AI search the library and read only the passage it needs. Ranked search working in Chinese and says so when nothing matches. • Share what you tune — Prompts, export styles and KB entries export as files. Install from the built-in library or add a source: any public GitHub repo or page. Updates are flagged, never automatic, and an edited copy is never overwritten. • Tool-using AI — Reads, searches, and writes workspace files. Optional web search via Brave, Tavily, Perplexity, or AISA. • Files done right — Open files from anywhere; create, rename, move, duplicate, delete; multiple pinned workspaces. • Local version control — Snapshot, diff, and revert on device: no git account, history never leaves it, instant in huge folders. Auto-commit optional. • Reliable by default — Suggests the right model for the job; dropped streams resume without re-sending the conversation. • Multimodal — Attach files, photos, or clipboard images. Vision models get them directly; PDF / DOCX / PPTX / XLSX are transcribed. • Trilingual — Full UI in English, 繁體中文, 简体中文; switch without a restart. • iPad and Mac — Three-pane Split View on iPad and Mac, tabs on iPhone, a full Mac menu bar and keyboard shortcuts. PRIVACY • API keys live in the Keychain (device-only). Your content goes straight to the endpoints you configure — no proxy, no telemetry. Chat history is local. REQUIREMENTS • iOS / iPadOS 17.0 or later, or macOS 14.0 or later. You provide the API keys for the services you use. For support, send mail to sportusagi@gmail.com.

dev HTML Playground (dHP) runs HTML written by ChatGPT or any AI on your iPhone: free, no ads, and no coding knowledge needed. No computer required. Copy the AI's reply, paste it, and it becomes your own app. Its data stays on your phone, and it opens from your Home Screen like a regular app. IF YOU'RE LOOKING FOR - A way to run HTML that ChatGPT made, on an iPhone, for free, with no ads and no programming knowledge - A place to keep the budget tracker or diary an AI built for you, with its data, and use it every day - A way to build your own tools without owning a computer - A quick way to view HTML documents an AI wrote for you FEATURES Code Editor A syntax-highlighted editor for HTML, CSS and JavaScript with autosave and file management (add, rename, delete). Smart quotes and other typing "corrections" that break code are disabled. Instant Preview Run your code with one tap. console.log output and errors appear in a built-in console, so you can debug entirely on your phone. AI Integration A ready-made environment prompt for AIs like ChatGPT and Claude. Paste it, and the AI asks "What would you like to build?" — just answer in plain words. Bring the returned code in with one tap using "Paste & Replace All". You can finish real apps with zero programming experience. Safe Data Storage Every project ships with storage.js, a simple persistence library. Your apps' data is stored safely and kept separate per project. It also works in regular browsers, so your creations are portable. 7 Templates - Game (Crowd Rush): the real version of that "grow your crowd" ad game - Game (Pull the Pin): the real version of that pull-the-pin puzzle from the ads - Empty Project: start from a clean slate - Basic Sample: learn the ropes with a counter and notes - To-Do List: a practical task app - Habit Calendar: a monthly habit tracker - Game (NEON RUSH): a full neon mini-game demo Add to Home Screen Register your apps as Home Screen icons via Shortcuts and launch them like regular apps. Export Export as ZIP (for backup) or a single HTML file (for sharing). Send your work via AirDrop, save to Files, or continue editing on a Mac. Opening a saved .html file is just as easy: share it from the Files app and choose dHP. HTML that an AI exported "as a file", or that you received via AirDrop, becomes one of your apps. HTML Viewer Copy any HTML (like a document an AI wrote) and view it with one tap. Everything you view is kept in a history, and you can import it as a project to edit. Built-in Browser A browser tab for research or chatting with AI sites, so the whole loop stays in one app. About your AI Works with any AI you like — ChatGPT, Gemini, Claude and more. Free AIs are fine; smarter ones just nail it on the first try more often. And if something breaks, dHP catches the error for you — copy it, paste it back to your AI, and it gets fixed. The interface is available in English, Japanese and Simplified Chinese. Everything is free, with no ads. Your "I want to build something" — right in your pocket.
