Bang! — the voice-first overlay agent
Bang floats above every app on your Mac as a single puck. Talk to it hands-free and it runs the commands, edits the files, opens your app in a real browser to check its own work — then tells you out loud the moment something breaks.
Runs on OpenAI, Anthropic, Google, or any OpenAI-compatible endpoint — Ollama, vLLM, or your own gateway.
Bang isn't a chat window you type into. It's an agent that listens, acts on your machine, watches what it built, and speaks up on its own.
Start talking and Bang transcribes as you go, notices when you've finished your thought, and sends it. No push-to-talk, no wake word, no window to focus first.
Replies are read back to you, so you can keep your eyes on your editor. Echo cancellation means you can cut it off mid-sentence — and it stops, listens, and picks up your new instruction.
A chip beside the composer shows whether your dev server is up or has crashed — and it stays there after the turn ends, because your server does. If your build dies, Bang says so unprompted instead of waiting to be asked.
Ask if something works and Bang opens the page in a real browser: uncaught
exceptions, console errors, requests that 404'd, and — on a vision model — a
screenshot it actually looks at. "It's running" becomes "it loads, but there's a
TypeError in app.js."
Shell commands, file edits, greps, dependency installs, long-running dev servers it can check back on later — and it can answer a CLI's y/n prompt while a process is still running.
Connect your own Cloudflare account and Bang can find an available domain, register it, point DNS at your site, and deploy it — end to end, in one conversation.
Draw straight onto the display to show Bang what you mean. Circle the broken button instead of describing where it is.
Connect MCP servers — Linear, Google Workspace, Cloudflare, your own — and Bang uses them as tools. One click to connect, no config files to hand-edit.
Ask for something big and Bang researches first, writes a plan you can approve, then works the checklist — delegating focused sub-tasks to subagents so the main thread stays on track.
An agent with a voice interface and real credentials needs hard stops, not vibes. Anything irreversible pauses and waits for a human — in the app and in the overlay.
Frontier APIs when you want the best answer. Self-hosted models when you need privacy, cost control, or offline. Switch mid-conversation — Bang doesn't lock you in, and its backend is yours to run.
Say what you want in plain language. The puck is always there, over whatever app you're in.
Bang plans, then shows you anything that spends money, installs software, or can't be undone.
It works, checks the result in a real browser, and reports back out loud — including the parts that broke.
