A Neovim plugin to interact with opencode.ai.

Name is not great, but didn't want to sit on opencode.nvim

Features

• Send the current filename to an opencode.ai session.
• Send the selected lines to an opencode.ai session.
• Support for multiple opencode instances running simultaneously.

Installation

Use your favorite plugin manager.

lazy.nvim

{
  "loukotal/neopencode.nvim",
  config = function()
    require("neopencode.main").setup({
      -- follows https://models.dev/
      -- needs to be setup in opencode
      provider_id = "google",
      model_id = "gemini-2.5-pro-preview-06-05",
    })
  end,
}

Usage

• :OpencodeSelectSession - Select an active opencode.ai session from all running instances.
• :OpencodeFile - Send the current file to the selected session (prefills @filename in prompt).
• :OpencodeSelect - Send the selected lines to the selected session (prefills @filename with selection).

Configuration

You can configure the plugin by calling the setup function.

require("neopencode.main").setup({
  provider_id = "anthropic",
  model_id = "claude-sonnet-4-20250514",
})

TODOs

• better session picking
• there should not be a setup for the model, it should use whatever the session was using
• there should be a way to select a model that is set up in opencode - so you can use a different model for each message when needed
• creating a new session does not update opencode ui and the session needs to be selected in opencode
