Is it possible to spell check PDF files? In Preview.app the "Edit > Spelling & Grammar > Check Document Now (⌘;)" is disabled. I'm working on a LaTeX document in Emacs and would like to use the OS X spell checker. A solution for accessing the built in spellchecking dictionary from Emacs would also be acceptable.


I would install aspell with a package manager like brew and then run that on the .tex file. Unless I'm mistaken emacs has support for aspell built-in.

You can also turn on spell checking in your terminal (iterm2) or emacs GUI.

  • That's a good list of options you are mentioning. Can you please add some details on how to install aspell and/or turn on spell checking in Terminal? – nohillside Sep 16 '12 at 9:09
  • This did not completely answer my question since it uses a custom dictionary file and not the OS X dictionary. But it is possible that this is still the best solution so I'll accept it for now :) – Adam Bergmark Sep 16 '12 at 15:18

    @patrix I am on OS X and installed aspell with homebrew brew install aspell --lang=en. I then added this to my .emacs (setq ispell-program-name "/usr/local/bin/aspell") (setenv "ASPELL_CONF" nil) (autoload 'flyspell-babel-setup "flyspell-babel") (add-hook 'latex-mode-hook 'flyspell-babel-setup) Spell check an entire buffer with M-x flyspell-buffer and check a word for spellings with M-x ispell-word, choose an alternative from the numbers or add to your dictionary with i. I'm using Carbon Emacs. Other dists my need you to install emacs' aspell manually. – Adam Bergmark Sep 16 '12 at 15:19
  • stackoverflow.com/a/19026248/240004 has good instructions on how to install emacs, aspell, and homebrew in a manner I prefer. – Randall Hunt Dec 4 '13 at 19:44
