Pair.nvim — agent copilot that keeps you inside the codebase

An editor plugin that keeps agent conversation and research assistance inside your codebase instead of replacing your hands on the code.

Problem

Developers love coding with agents but notice their own knowledge of the codebase regressing — the agent edits, the human trails behind. They want agent speed while keeping control over what gets written and where, and want to stay immersed in the code rather than in a chat window. There's no ergonomic tool for this 'both'.

Solution

A Neovim plugin that embeds agent chat, codebase research and assistance as a side panel/floating layer rather than letting the agent edit files directly. Every agent suggestion is presented as a reviewable diff, split into small understandable steps, so the user always works inside the code — never banished to a chat tab.

Users

Senior developers on Neovim/Vim who want human-in-the-loop coding and don't want their codebase understanding hollowed out by agents.

MVP

Neovim side-panel chat; buffer- and project-aware retrieval Q&A; agent suggestions shown as diff previews with per-hunk confirm; saved local session history; safe default of never auto-writing files

Revenue

Open-source MIT core plus paid support/config packs; or a commercial edition with team-shared sessions and private deployment.

Why now

As coding agents go mainstream, 'agents erode my understanding of the codebase' is becoming a public complaint — a counter-trend demand that a single dev can address with a high-quality editor plugin.
