SimpleLime

SimpleLime is a small native macOS editor for the text you do not want to carefully organize yet: drafts, copied snippets, Markdown notes, TODOs, logs, and temporary files that still need to survive a reboot.

It keeps scratch buffers in the restored session, opens regular text files, shows line numbers, highlights the current line, wraps text by default, and gives you the daily editor basics: search, replace, regex, find across tabs, multi-cursor basics, and text transforms.

There is also a primitive per-tab AI chat through Agent Client Protocol. Copilot works through the GitHub Copilot CLI ACP server, and Codex can be wired through a compatible ACP command when one is available.
