AI Code Converter
Translate code between Python, JavaScript, TypeScript, Java, C++, Go, and Ruby using on-device pattern-based transpilation for common constructs (loops, conditionals, functions, classes, variables, prints, lists, dicts, comments). Idiomatic output, change explanations, side-by-side diff, library/dependency mapping notes, comment-preservation toggle, snippet-vs-file mode, language auto-detect, unsupported-feature flags, copy/download, local history (localStorage, last 20), and shareable URL. 100% client-side. Optional BYO-key LLM enhancement for complex translations — your code never leaves the browser unless you choose to call your own provider.
