Most AI editors suggest. Nexa executes — carefully. Every capability below ships in the build you download today.
When Nexa proposes a change, it doesn't just push it into your file. The old code dims, the new code appears as a live overlay, and a full side-by-side diff opens next to it.
Even in fully autonomous mode, anything that could lose work — deleting files, overwriting a module, clobbering a move — pauses and asks first. Session-wide trust is yours to grant, never assumed.
Queue background agents that keep working after you close the tab. Watch the work log live, then apply the result to your workspace as a patch — or send a follow-up.
Five hand-tuned themes ship built-in — two with living, animated scenery rendered straight into the workbench. No extensions, no setup.
Nexa is built on the world's most-loved editor foundation. Your keybindings, your settings, your extensions and your muscle memory come with you.
Download Nexa, open a project, and tell it what you want to build.
Download for WindowsNexa is free to download and use as your daily editor. Sign in with Google to get your free key — it unlocks the AI agent and cloud features, and lives on your dashboard any time you need it.
Yes. Nexa is built on the same open-source foundation, so your extensions, keymaps, settings and themes carry over — most people are productive in the first minute.
Your code lives on your machine. When you ask the agent for help, only the context needed for that request is sent, encrypted in transit. Destructive actions always require your explicit approval.
Nexa updates itself quietly in the background. Every release is checksummed, and you can verify any download against its published SHA-256.
