AI Rules: CLAUDE.md & Cursor

MDPilot is the mobile editor for AI coding context files. Write, lint, and organize your CLAUDE.md, .cursorrules, AGENTS.md, and copilot-instructions right on your phone, render Mermaid diagrams, and keep your prompt library a tap away — all offline, on-device, no account.

CONTEXT STUDIO — AI RULES & CONTEXT FILE EDITOR

Keeping CLAUDE.md, AGENTS.md, .cursorrules, and copilot-instructions well-formatted is part of every AI-native developer workflow. Context Studio is a structured editor and linter built for these files: it checks syntax, flags errors, and exports finished context files straight to your project. Capture an idea for your agent rules on the go, fix a broken .cursorrules from your phone, or draft an AGENTS.md while you are away from your desk.

- Structured editor for CLAUDE.md, AGENTS.md, .cursorrules, and copilot-instructions
- Built-in linter that checks syntax and flags formatting errors
- Templates and scaffolds for common AI rules and context files
- Export context files directly to any app or to your project

PROMPT VAULT — YOUR AI PROMPTS, ONE TAP AWAY

Store your AI system prompts, writing templates, and reusable LLM instructions, organized by category. Search, copy, and reuse them across Claude, ChatGPT, Cursor, or any AI tool — without retyping or digging through old chats.

MERMAID DIAGRAMS — DIAGRAM AS CODE

Render flowcharts, sequence diagrams, class diagrams, ER diagrams, state machines, and Gantt charts live from Mermaid text. Paste the diagram your AI generated and see it rendered instantly inside your document.

MARKDOWN EDITOR WITH LIVE PREVIEW

Open any .md, .markdown, or .mmd file and edit with a real-time split-screen preview: headings, bold, italic, lists, tables, code blocks, blockquotes, and task lists. A formatting toolbar and snippet drawer insert structure in one tap. Switch between edit mode, full preview, or side-by-side at any time.

PRIVATE BY DESIGN — FULLY OFFLINE

Everything stays on your device. No account, no cloud sync, no upload. Write, edit, preview, and manage files with no internet connection.

Pro removes ads and unlocks the LAN Vault Server. One-time payment, no subscription, no recurring fees, no account required.
