CodeCompanion doesn’t have tab completion right? I love Neovim but Cursor’s tab completion is just next level and I haven’t found any nvim plugin that comes close to it.
Nvim 0.12 (prerelease) also has ghost text with the "textDocument/inlineCompletion" LSP server capability[1]. Currently supported by the "copilot" config[2], but any LS that supports "textDocument/inlineCompletion" can be used (and the config[2] shows optional QoL improvements).
