JetBrains Revives Dead Project as Air AI Coding Tool

The short version

JetBrains Air is a new AI-powered coding app from JetBrains that lets multiple smart AI "agents" handle programming tasks at the same time, like having a team of robot assistants building your software. It's built on the bones of their canceled Fleet tool and is now available in public preview for Mac (Windows and Linux coming soon). For everyday people, this could mean apps and websites get built faster and cheaper in the future, but it won't change your phone or laptop right now—it's mainly for developers making the tech you use.

What happened

Imagine you're a chef trying to cook a big meal. Normally, you'd chop veggies, stir the pot, and check the oven one task at a time. Now picture handing off jobs to a team of helpers who work side by side without bumping elbows—that's what JetBrains Air does for coding. JetBrains, a company famous for its popular coding software like IntelliJ IDEA (think of it as a super-powered notebook for programmers), just launched "Air" in public preview. It's designed for "agentic AI," which means AI helpers (called agents) that don't just suggest code—they actually run whole tasks, like building a web app section or fixing bugs, all happening in parallel.

Air revives Fleet, an experimental coding tool JetBrains ditched late last year because it overlapped too much with their main products and didn't catch on. Fleet stopped new downloads after December 22, 2025, though old installs might limp along for a bit. Instead of letting it rot, JetBrains repurposed its tech into Air, adding support for top AI brains like OpenAI's Codex, Anthropic's Claude, Google's Gemini, and their own Junie agent. You describe a task in plain words—like "build a login page"—and Air delegates it to these agents, who work in your local files, Git branches, Docker containers (fancy virtual boxes), or soon cloud setups. A built-in code editor lets you switch tasks, review results, and approve changes.

They also released Junie CLI, a standalone command-line version of their AI agent that works on Mac, Windows, and Linux without needing their full software. It costs $10/month for solo users up to $60 for big teams, or you can plug in your own AI subscription keys. Local AI models (ones that run on your own computer without internet) are on the wishlist but not ready yet.

This is JetBrains' bet on the future of coding, where AI does more heavy lifting amid a crowded market of AI tools from companies like Anthropic and Google.

Why should you care?

You might not code for a living, but developers using tools like Air will build the apps, websites, and software you rely on every day—like your banking app, Netflix recommendations, or the next viral game. If AI agents make coding faster (by running multiple jobs at once), software could ship quicker, with fewer bugs, and at lower costs. That might mean cheaper subscriptions, more frequent updates to your favorite tools, or innovative features arriving sooner. On the flip side, if you're not a coder, this doesn't touch your daily routine yet—it's not like ChatGPT for emails. But as AI spreads, expect ripple effects: smarter e-commerce sites, faster custom business tools, or even hobby projects turning into real products quicker.

What changes for you

For non-coders, zilch right now—Air is preview software for pros, not a consumer app. Your apps won't update overnight. But if you're a small business owner needing a custom website, a freelance designer teaming with devs, or just a tinkerer messing with code on the side, Air could make those projects speedier and less expensive down the line. Developers loyal to JetBrains' IntelliJ tools (used by millions for Java, Kotlin, and more) might stick put, wondering if Air's worth switching—JetBrains has to balance both worlds. Pricing starts pay-what-you-use for AI "tokens" (like buying ink for a printer), so no huge barrier. Try the Mac preview free now if you're curious, but everyday users: bookmark this; in a year, you might notice apps feeling snappier thanks to agent tech.

Frequently Asked Questions

### What is an "AI agent" and why is it a big deal?

An AI agent is like a smart robot assistant that doesn't just give advice—it takes a job description and does the work itself, such as writing code or testing features. In Air, multiple agents team up on different parts simultaneously, like construction workers building a house's walls, roof, and plumbing at once instead of one after another. This speeds up software creation, which could lead to better, faster apps for everyone.

### Is JetBrains Air free to try, and how much does it cost?

Yes, Air is in public preview right now, so you can download the Mac version for free to test it (Windows and Linux versions are coming soon). The related Junie AI agent costs $10/month for individuals or $60 for enterprise, but you can use your own keys from OpenAI, Anthropic, or others to avoid extra fees. No word yet on final pricing post-preview.

### How is Air different from regular coding apps like VS Code or ChatGPT?

Unlike basic code editors (like VS Code) or chatty AIs (like ChatGPT that just suggests snippets), Air is built for "agentic" work where AIs run full tasks in parallel across environments like Docker or Git. It's not a ChatGPT clone—it's a whole workbench for AI teams. VS Code users might see similar AI add-ons, but Air focuses on multi-agent coordination using open standards like ACP for future-proofing.

### Will this replace tools like IntelliJ IDEA that developers already use?

Not immediately—IntelliJ is JetBrains' flagship for traditional coding and has a huge fanbase. Air is an AI-specialized spin-off from the scrapped Fleet project, aimed at the "next wave" of AI-driven development. Loyal users might ignore it, but JetBrains hopes Air carves a niche without cannibalizing IntelliJ.

### When can regular people use Air, and does it need fancy hardware?

It's preview-only for developers now—grab it from JetBrains if you're on Mac. No specific release date for full version, but Windows/Linux are "promised later." It works with cloud AI services, so your computer doesn't need superpowers, though local models (for privacy/offline use) are planned but undated.

The bottom line

JetBrains Air is a fresh shot at AI-powered coding by recycling their failed Fleet experiment into a multi-agent playground that could turbocharge how software gets made. For you, the non-techie, it signals exciting times ahead: faster apps, innovative tools, and potentially lower costs as devs wield AI teams like pros. It's not reshaping your world today—stick to your current apps—but watch this space. If you're a hobby coder, dive into the preview; otherwise, this is one more sign AI is making behind-the-scenes magic happen quicker. JetBrains is playing catch-up in a wild AI dev race, and success here could mean smoother digital life for all.
