Sidekick.nvim is nice, you get a "real" terminal window on the side with many different agents to choose from.

Either opencode, claude, gemini, copilot, basically most that are relevant :D

Its a pretty light connection-layer, so it helps with sending context.

Mentioned elsewhere, but

:term claude

In a split goes a long way for me!

I just run them in separate terminals. The only real gap was that I couldn't tell the robot to open files in nvim when I wanted to look at them, the way it could in other IDEs, so I whipped up a quick skill (https://github.com/mkozlows/nvim-skill) to do that.

What I do is use 'C-z' and 'fg' to suspend and resume my editor when I need.

Pressing C-z on neovim puts me back in the terminal so I can do whatever I need to do and when that is done I just type 'fg' in the terminal and it opens up my neovim again, exactly as it was.

Yes tab split, neovim on the left, companion on the right, or different tabs. The plugin codecompanion.nvim is also great. I use it for common tasks. Like:

vaf (visual around function) <space>ad (leader key add docstring).

And it documents the functions with my system prompt instructions for what good docstings should look like.

This is why I switched to cursor over the last few months out of nvim. Just wasn't any smooth first class integrations with AI tooling. I still use vim bindings there, and I use nvim for quicker edits, but the AI editing and Cursor Tab is just way better than the AI stuff in nvim.

Just open a terminal split/tab and use claude there. The neovim buffer will update real-time.

Ghostty split panes - coding TUI in one pane, neovim in the other, maybe a third pane for shell.

Just use this; it's literally claude code in a terminal tab in vim; also aware of what files are open in vim.

Am I misremembering cause I could have sworn that Aider started out as a nvim plugin?? https://github.com/Aider-AI/aider

Check out avante.nvim: https://github.com/yetone/avante.nvim

CodeCompanion.nvim is a pretty nice plugin. I use that for quick stuff and opencode in the embedded terminal for larger tasks.

Use no plugins, install Zellij (or tmux) and use in split panes, works great.

I just have vim open in one terminal tab and Claude Code open in another terminal tab. Works great.
