Google Chrome Dictionary Location

It doesn't appear that there is a user-editable file with the default dictionary in it. I just looked through the .app folder and saw nothing like a dictionary. Also, ~/Library/Application\ Support/Google/Chrome/Dictionaries/ doesn't list any dictionaries.

OS X

The file for the custom dictionary is:

/Users/<username>/Library/Application Support/Google/Chrome/Custom Dictionary.txt

You may also find it at:

/Users/<username>/Library/Application Support/Google/Chrome/Default/Custom Dictionary.txt

In the comments, it's mentioned that you can find “misclicks” here, too, which is related to how OS X handles its dictionary:

/Users/<user>/Library/Spelling/LocalDictionary

Windows XP and Windows 7/Vista

It appears it's in (for Windows XP and Vista/7, respectively):

C:\Documents and Settings\%USERNAME%\Local Settings\Application Data\Google\Chrome\User Data\Custom Dictionary.txt
C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default\Custom Dictionary.txt

Linux

The location depends on whether you're running Chromium or Google Chrome

Chrome: ~/.config/google-chrome/Default/Custom Dictionary.txt

Chromium: ~/.config/chromium/Default/Custom Dictionary.txt

---

If you are using a non-default profile, instead of the directory named Default, check for a directory named Profile n where n is a number starting from 1.

For future reference, I found it under:

/Users/username/Library/Application Support/Google/Chrome/Default/Custom Dictionary.txt

OSX Lion 10.7.4
Chrome 19.0.1084.56

Add a new word to the dictionary

Windows, Chrome OS, and Linux only: Words that you choose to add to the dictionary are added to your "Custom spelling dictionary".
