AI Code Editor & Compiler

AI Code Editor & Compiler is a mobile IDE for writing and running real programs on your phone or tablet. Type Python, Java, C++, C#, JavaScript, PHP, SQL or one of 25+ other languages, tap Run and see the output in seconds. When something breaks, the built-in AI assistant explains the error and suggests a fix.

No setup, no toolchains, no laptop. Your programs build and run on our cloud servers, so heavy work does not drain your battery (running needs an internet connection). Use it as a Python compiler, a Java IDE, a C++ compiler, a PHP editor or an SQL editor: one app instead of ten.

HOW IT WORKS
1. Pick a language, open a blank file or start from an example
2. Write in a code editor built for touch screens
3. Tap Run and read the real output a few seconds later
4. If it fails, ask the assistant what went wrong and get a corrected version

WRITE
• Syntax highlighting for 30+ languages and formats, from Python and Java to HTML, CSS, JSON, YAML and Markdown
• Smart keyboard bar with the brackets, quotes and symbols programmers use most
• Find & replace, adjustable font size and tab size, line numbers, word wrap, light or dark theme
• Open a file from your device, attach notes to a snippet, share it as a link
• Multi-file projects for work that outgrows a single file
• Split view keeps your program and its output or preview on screen together

RUN
• Code runner for Python, Java, C, C++, C#, JavaScript, TypeScript, Kotlin, Swift, Go, Rust, PHP, Ruby, SQL (SQLite), Lua, R, Scala, Haskell, Perl, Bash and more
• HTML, CSS and JavaScript render in a live preview next to your markup
• Every run shows the real output or the real error message, not a simulation
• History keeps recent snapshots, so you can roll back after an experiment

DEBUG AND IMPROVE WITH AI
• Fix: send a failing program and its error to the assistant and get a corrected version back
• Explain: select a few lines and ask what they do, step by step
• Optimize, rewrite, format, write a unit test or translate a snippet into another language
• Generate a first draft from a plain description when you are stuck
• Review: get a code review that points out the most important improvement (Pro)
• Pick the language model you prefer
• Optimize, rewrite, format and translate results open as a diff you review before applying

PRACTICE AND KEEP YOUR WORK
• Examples library with ready-made snippets to start from
• Java practice missions with real tasks to solve: a few are free, the rest come with Pro
• Save snippets to your account and continue where you left off

WHY A POCKET IDE
Ideas rarely wait for your desk. A bug you think of on the bus, a homework question between classes, an interview problem in a waiting room: open the app, type, run, done. Reading an error message and fixing it yourself is how syntax turns into skill, and the assistant is there when you want a second pair of eyes.

FREE AND PRO
The editor and the compilers are free to use, with ads. Free users get one AI request a day, plus one more by watching a short ad. Pro removes ads, lifts that daily limit and unlocks the code review and every practice mission.

WHO IT IS FOR
• Students who need a Java compiler or a C compiler for homework on the go
• Developers testing an idea, an algorithm or an SQL query away from the desk
• Interview candidates practicing problems anywhere
• Web learners using it as an HTML editor, with CSS and JavaScript changes in an instant preview
• Anyone who has ever emailed themselves a script "to try later"

The interface is available in 22 languages.
