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.
