Backgrind

Backgrind is an always-on-top overlay that runs your AI coding agent (Claude Code, Cursor, Codex, or the built-in Grindy agent) over any app, even a fullscreen game. It only pings you when it actually needs a decision, so you stay productive — or keep playing — while it handles background work. Plug in your own agent CLI (a thin frontend over your real CLI, so prompts and code never touch their servers) or use hosted Grindy out of the box. Features multi-agent tabs, voice, Build/Plan and click-through; works like a Discord/OBS overlay with no game-memory reading or input injection. Featured on Product Hunt (June 21, 2026).
