How to Set Up and Use Neovim Gemini

nvim-gemini-companion is a Neovim plugin that embeds Google Gemini CLI and QwenLM Qwen-code directly into your editor workflow through a persistent sidebar and terminal sessions. It lets you send selected code, buffer content, or LSP diagnostics to an AI agent and receive diffs you can accept or reject without leaving Neovim. Developers use it to get in-editor AI code assistance from Gemini or Qwen-code while keeping their existing keybindings and LSP setup intact.

Prerequisites

  • Neovim 0.9 or later
  • nvim-lua/plenary.nvim plugin installed
  • gemini-cli (Google Gemini) and/or qwen-code (QwenLM) installed and available in PATH
  • A Neovim plugin manager such as lazy.nvim or packer.nvim
  • An MCP client is not required — the plugin communicates directly with the CLI tools
1

Install gemini-cli and/or qwen-code

At least one of these CLI tools must be installed and accessible from your shell PATH before the plugin will function. Follow the official installation instructions for each tool you want to use.

# Verify tools are in PATH after installing them
which gemini
which qwen-code
2

Add the plugin to your Neovim config

Add nvim-gemini-companion to your plugin manager. The example below uses lazy.nvim. Adjust the cmds list to include only the agents you have installed.

{
  "gutsavgupta/nvim-gemini-companion",
  dependencies = { "nvim-lua/plenary.nvim" },
  event = "VeryLazy",
  config = function()
    require("gemini").setup({
      cmds = { "gemini", "qwen" },
      win = {
        preset = "right-fixed",
        width = 0.35,
      },
    })
  end,
}
3

Install plugins and restart Neovim

Run your plugin manager's install command (e.g., :Lazy sync in lazy.nvim), then restart Neovim to load the plugin.

4

Open the AI sidebar

Use the :GeminiToggle command to open or close the companion sidebar. The sidebar hosts the terminal session with your chosen AI CLI.

:GeminiToggle
5

Send code or diagnostics to the AI

In visual mode, select a code block and run :GeminiSend to send it to the AI. To forward LSP diagnostics, use :GeminiSendLineDiagnostic for the current line or :GeminiSendFileDiagnostic for the whole file.

:GeminiSend
:GeminiSendFileDiagnostic
6

Switch between Gemini and Qwen-code

If both agents are configured, use the terminal switching keybindings Alt+] and Alt+[ to cycle between active AI sessions.

Neovim Gemini Examples

Client configuration

This plugin is configured entirely inside Neovim's Lua config and does not use an MCP client JSON config. Add this to your init.lua or lazy.nvim spec.

require("gemini").setup({
  cmds = { "gemini", "qwen" },
  win = {
    preset = "right-fixed",
    width = 0.35,
    height = 0.8,
  },
})

Prompts to try

After opening the sidebar, type these prompts directly in the AI terminal session or send selected code with :GeminiSend.

- "Explain what this selected function does and suggest improvements."
- "Here are my LSP errors — how do I fix them?"
- "Refactor this code to use async/await instead of callbacks."
- "Write unit tests for the selected module."

Troubleshooting Neovim Gemini

':GeminiToggle' reports 'gemini command not found'

Make sure gemini-cli is installed and its binary directory is in your shell PATH. Start Neovim from a terminal where 'which gemini' returns a valid path.

Plugin loads but no sidebar appears

Confirm plenary.nvim is installed and loaded before nvim-gemini-companion. Run ':checkhealth' to verify dependencies, and check that the plugin's event trigger ('VeryLazy') has fired.

:GeminiSend has no effect when called in visual mode

Ensure you enter visual mode (v or V), select text, and then run :GeminiSend. The command must be called while a visual selection is active and the sidebar session must already be started with :GeminiSwitchToCli.
