Professional Code Editor Syntax highlighting for Python, JavaScript, HTML, CSS, JSON, and Markdown keeps your code readable and structured. Line numbers, smart auto-indent, find & jump to line, customizable font size and code themes — everything you need for efficient editing on a small screen. Multi-level file and folder management with create, rename, move, copy, and delete. Accidentally deleted something? The recycle bin keeps files for 7 days. Split View & Enhanced Output Split view places the editor and console side by side — write code and see results in real time without switching screens. The console supports colorful output, ANSI escape sequences, Rich library tables and progress bars. Adjustable output speed, auto-scroll, and one-tap clear make long outputs easy to handle. Developer Toolbox A built-in collection of everyday tools for debugging and data work: JSON Formatter: beautify or minify with one tap Encoder / Decoder: URL, Unicode, Base64, MD5 — bidirectional API Tester: custom headers and body, full response view QR Code Tool: generate and scan, with photo library import Timestamp Converter: seconds and milliseconds, multi-timezone Base Converter: binary, octal, decimal, hexadecimal Regex Tester: live match highlighting for quick validation Image Tools: image to Data URL, HTML to image AI Coding Assistant Stuck on an error? Can't figure out the logic? Bring up the AI assistant with one tap, describe what you need in plain language, and let it edit the code directly in the editor — no copying and pasting required. Built-in shortcuts for code review, adding comments, optimizing logic, and fixing errors. Multi-turn conversation and retry support means you can keep refining until you're happy. Don't like the result? Discard it — your original code stays untouched. Connect your own API key for DeepSeek or any compatible service. Fully configurable endpoint, key, and model.
