Asm Editor

Documentation The editor comes with built-in documentation for the M68K, MIPS, RISC-V and Z80 instruction sets including the valid addressing modes, description and examples for each instruction, directive and syscall. Visit the documentation Code completion Write and learn faster with the code completion tools, suggesting you with the valid addressing modes and shortcuts for labels and other keywords. Real time semantic errors that warn you before you compile the code. Tools & Customisation Feature rich tools to help you debug your code. Includes breakpoints, stepping, undo, stack tracer, register/memory diffing, decimal/hexadecimal conversions, stdout/stdin/errors, customisable shortcuts and settings, formatter and more. You can also customise the theme of the editor to your liking. Peripherals Programs can draw on a screen and interact with the user through mouse and keyboard or use the terminal for stdout and stdin. Available for M68K, MIPS, RISC-V and Z80. This can also be used to write simple interactive games and programs. Exam Create exams for students with the Exam tool where the editor is locked down. AI Chat Chat with an AI assistant that can write, run and debug assembly code directly in the browser. Use the AI Chat to get help with M68K, MIPS, RISC-V, X86 and Z80 assembly. Embed Embed the editor in your website to show and teach how assembly works using the Embedder tool Published research ASM Editor is described in a peer-reviewed paper presented at the 2026 IEEE Global Engineering Education Conference, together with the first-year course it was built for.
