03. How to install Codeium on Neovim

Codeium is an alternative to GitHub Copilot with the caveat that it is free for individuals. I rate Codeium very positively and Copilot is equal to it.

Installation using plug.vim is easy, you just need to edit your init.vim.

Paste in:

" Free AI codium
Plug 'Exafunction/codeium.vim', { 'branch': 'main' }

The resulting init.vim will look like this:

call plug#begin(has('nvim') ? stdpath('data') . '/plugged' : '~/.vim/plugged')
" Free AI codium
Plug 'Exafunction/codeium.vim', { 'branch': 'main' }
call plug#end()

And we restart Neovim. Type q at the command prompt with Ctrl + : and restart Neovim.

After rebooting, we do a PlugInstall and reboot Neovim once more.

The last step will be to set the Codeium configuration, by typing CodeiumEnable into the command line.

Codium will prompt you to connect the API to the Codium server.

And everything should work for you.
