Vim vs Overleaf

In this article, I compare these two approaches to editing LaTeX documents on Overleaf:

  1. Edit directly using Overleaf's editor.
  2. My setup: fetch from Overleaf using git, edit locally (using vim, pdflatex, and macOS Preview), and push to Overleaf using git.

Advantages of Local Editing over Overleaf

  1. Offline use: Local editing is very useful in flights or areas with spotty connectivity. Sometimes I have lost changes with Overleaf.
  2. I can use git to check diffs, create branches, and selectively commit/discard changes.
  3. With a local PDF viewer, I can go back after clicking a hyperref.
  4. Overleaf's custom PDF viewer doesn't have the bookmarks sidebar. I can use the browser's PDF viewer instead of Overleaf's custom viewer to get back bookmarks, but then I lose dark mode and synctex.
  5. Spellcheck: Vim can iterate over typos. Vim can have per-project spellfiles.
  6. In vim I can set scrolloff=8. Then vim starts scrolling the screen a few lines before the cursor reaches the end of screen.

Advantages of Overleaf over Local Editing

  1. Multiple people can simultaneously edit the document.
  2. SyncTex: I can jump from position in PDF to position in code and vice versa.

Features Available in Both Setups

  1. Smart Autocomplete: In vim, this can be achieved using the TexLab plugin.
  2. Dark mode PDFs: As of Feb 2026, Overleaf can display PDFs in dark mode using the CSS filter invert(95%) hue-rotate(180deg) brightness(90%) contrast(90%);. As of macOS Tahoe 26.5.1, the default PDF reader supports dark mode. Dark mode is also supported by some third-party PDF readers, like Skim and Acrobat Reader. Once can also generate PDFs in dark mode using github:sharmaeklavya2/tex-colorscheme.
