Want to try out AI-assisted coding? Let’s check out a few plugins that provide AI-based code completion for Neovim and VS Code.

Check out the following article for more tips and tricks to configure a modern Neovim development environment!

Tabnine

Tabnine is a mature AI assistant and supports all major IDEs, including Vim/Neovim and VS Code.

Neovim

For Neovim, you can use coc.nvim, deoplete.nvim, or nvim-cmp.

• I am going to use nvim-cmp. Below I use packer.nvim to install cmp-tabnine together with other plugins.

use {
      "hrsh7th/nvim-cmp",
      requires = {
        "hrsh7th/cmp-buffer",
        "hrsh7th/cmp-nvim-lsp",
        "quangnguyen30192/cmp-nvim-ultisnips",
        "hrsh7th/cmp-nvim-lua",
        "octaltree/cmp-look",
        "hrsh7th/cmp-path",
        "hrsh7th/cmp-calc",
        "f3fora/cmp-spell",
        "hrsh7th/cmp-emoji",
        "ray-x/cmp-treesitter",
      },
      config = function()
        require("config.cmp").setup()
      end,
    }
use { "tzachar/cmp-tabnine", run = "./install.sh" }

• In cmp.lua, I configured cmp-tabnine as one of the completion sources.

cmp.setup {
    formatting = {
      format = function(entry, vim_item)
        -- fancy icons and a name of kind
        vim_item.kind = require("lspkind").presets.default[vim_item.kind] .. " " .. vim_item.kind
-- set a name for each source
        local menu = ({
          buffer = "[Buffer]",
          nvim_lsp = "[LSP]",
          ultisnips = "[UltiSnips]",
          nvim_lua = "[Lua]",
          cmp_tabnine = "[TabNine]",
          look = "[Look]",
          path = "[Path]",
          spell = "[Spell]",
          calc = "[Calc]",
          emoji = "[Emoji]",
          treesitter = "[treesitter]",
          neorg = "[Neorg]",
        })[entry.source.name]
       if entry.source.name == "cmp_tabnine" then
          if entry.completion_item.data ~= nil and  entry.completion_item.data.detail ~= nil…
