geass.nvim

local AI inline completions in Neovim.

how it works

Hits your local model with prefix+suffix around the cursor, streams back a completion, shows it as ghost text. Accept with <Tab>, dismiss with <Esc>, trigger manually with <M-CR>(alt+enter).

requirements

• Neovim >= 0.10 (uses vim.text.diff)
• Ollama running locally (default provider)
