Stop hand-copying AI code changes into your files.

Paste AI output → preview the diff → apply it. One click. Full undo, always.

Brud Code Editor View

No API keys. No subscription. Works with ChatGPT, Claude, Gemini — any chatbot.

If you use AI chatbots to write code, you already know the friction: copy a function, find the file, paste it, hope you didn't miss a line, repeat for the next file. Brud Code removes that step. Your AI outputs a change; Brud applies it — reviewed, logged, and reversible — in one click.

The whole workflow is one paste, one copy

Most AI coding tools stop at "apply the change." Brud closes the loop back to your AI too — so it always knows what actually happened, without you typing a status update by hand.

File Path: src/utils.js
<<<<<<< SEARCH [1]
function calculateTotal(price, tax) {
  return price + tax;
}
=======
function calculateTotal(price, tax, discount = 0) {
  return price + tax - discount;
}
>>>>>>> REPLACE [1]

Paste — your AI hands you a Brud block like the one above. Drop it into the sidebar.
Execute — Brud shows you the diff and applies it. Works identically whether it's 1 file or 1,000.
Copy All — one click copies everything your AI needs back: status, file paths, messages, per-file results.
Paste it back — drop that into the chat. Your AI now knows exactly what happened, and picks up right where it left off.

One paste in. One copy out. No retyping results, no re-explaining what changed, no switching back and forth to check if something failed.

Why people switch to Brud Code

🆓 Free, forever, no keys. Works with any chatbot's web UI — nothing to configure, nothing to pay for.
🔁 One paste in, one copy out. The AI's result — status, files, errors — comes back to it automatically, no manual re-explaining.
👀 You approve every change. Nothing touches your files until you preview the diff and hit apply.
⏪ One-click undo, at any scale. Revert a single edit or an entire thousand-file session in one action.
⚡ Built for bulk. Create, patch, or restructure hundreds of files from a single AI-generated block.
🔓 No lock-in. No Git required, no account, no server — your history lives in your own workspace.

What it does


File Operations	Create, delete, rename, move, copy, and append files — reviewed and reversible every time.
Bulk Operations	Apply one transformation across hundreds or thousands of files in a single pass.
Code Discovery	Give your AI a token-efficient map of your project so it writes changes that actually fit.
Terminal	Run commands, chains, and interactive CLI tools, with output routed straight back to the AI.
Any AI, Any Time	Works with ChatGPT, Claude, Gemini, DeepSeek, Grok, Llama — anything that can output text.
Settings	Restrict Brud to your workspace and control which tools the AI is allowed to use.
My Prompts	Save, version, and reuse your own prompts with dynamic fields that fill in on the fly.

It's fast — and we proved it

Tested on a real 384K LOC codebase, manually verified end to end:

Benchmark	Scale	Result	Time
Create Files	1,000 files	1,000/1,000 created, unique content	Under 1 second
Search & Replace	467 files / 384K LOC	467 patched, 0 failed	Milliseconds
Append Multi	467 files	467 modified, 0 failed	Milliseconds
Revert Session	1,000 files	1,000/1,000 reverted	Milliseconds
Restore Session	1,000 files	1,000/1,000 restored	Milliseconds

100% success rate across every benchmark. No manual per-file work — the AI generates one block, Brud handles the rest.

Your history, your machine

Every session is automatically snapshotted before and after, stored locally in .brud/history/ in your own workspace — no account, no cloud, no external service. Revert or restore any session instantly, even months later (deleted sessions get a 7-day recovery window before cleanup). Full technical details are in ARCHITECTURE.md.

Let your AI edit your files directly

If your AI tool supports MCP (a standard way for assistants to use outside tools), Brud can plug into it. Instead of copying a change out of the chat and pasting it into your files, you connect Brud once and your assistant sends the change straight to Brud.

You keep the same safety net. Brud only touches the project you opened, every change is saved, and anything can be undone in one click from History.

What you get: ask your AI for a change, watch it land in your files, and undo it like any other Brud action — no copy-paste in between.

Setup lives in the extension. Open Brud Code: Open Brud Code Management and use the MCP tab: Start, Stop, a switch that decides whether Brud starts with your project, and a button that copies connection details you can paste into your AI tool. Brud starts on its own when you open a project unless you turn that switch off.

For now you install the extension from this repository rather than the marketplace; the setup guide has the steps.

FAQ

Do I need an API key?

No. Brud Code works with any chatbot's free web UI. Paste the AI's output directly — no keys, tokens, or subscriptions.

Does Brud send anything anywhere?

Your project history and snapshots stay in your workspace. The extension does send anonymous operation records, including redacted diagnostics when something fails, so bugs can be found and fixed. PRIVACY.md lists the exact fields, the redaction rules and how to inspect the traffic yourself.

Is it really free?

Yes — free and open source under the MIT license.

Which AI chatbots work with it?

Any chatbot that outputs text: ChatGPT, Claude, Gemini, DeepSeek, Grok, Llama, and more.

Where did Brud Code come from?

Brud Code is a fork of Akkhar Code Patcher, which is no longer maintained. Brud Code is its official continuation under a new identity.
