nomoji.dev is a free platform that provides configurable rules to control emoji usage in AI-generated code, documentation, console output, and logs. It works with popular AI coding assistants like Cursor, Claude Code, GitHub Copilot, and Google Gemini CLI.

Why should I avoid emojis in code?

Emojis in code can reduce accessibility for screen readers, create inconsistent rendering across platforms, make text harder to search and parse, appear unprofessional in enterprise contexts, and clutter technical output and logs.

How do I use nomoji with Cursor?

For Cursor, create a .cursor/rules directory and download the nomoji rules file: mkdir -p .cursor/rules && curl https://nomoji.dev/api/cursor-rules/default -o .cursor/rules/nomoji.mdc

Yes, nomoji.dev is completely free to use. It's open source and runs on Cloudflare Workers. There are no premium features or paid tiers.

Can I customize the emoji rules?

Yes, you can customize rules using the API. Choose from three presets (strict, moderate, relaxed) or create custom configurations for specific contexts like documentation, console output, CLI tools, logging, comments, commit messages, and UI text.

Does nomoji work offline?

Once you download the rules files for your AI assistant, they work offline. The API requires internet access for configuration updates and text analysis.

Which AI assistants does nomoji support?

nomoji supports Cursor, Claude Code, GitHub Copilot, Google Gemini CLI, Codeium, Tabnine, and other AI coding assistants through generic templates. It also provides Git hooks for additional enforcement.
