Terminal Writing Tools
Writing in the terminal means prose rather than source code: journals, drafts, essays, papers and finished documents.
The tools include word processors that run in a text screen, journaling programs that open a dated entry with one command, citation and bibliography managers for academic work, and spelling and style checkers that read a draft back to the author. Output stays as plain text or Markdown, which diffs cleanly and keeps well in version control.
Editors aimed at code are under text editors, and shorter captured thoughts are under note taking.
