Green Robot AI is a power-optimized AI service that automatically chooses the best AI for every question. This slashes energy consumption compared to mainstream AI sites, while still using the most advanced models when needed.

How it Works

Think of it like lighting your home. You wouldn't fire up a stadium floodlight to read a book in bed — a bedside lamp does the job perfectly and uses a tiny fraction of the electricity. Most AI services give you the floodlight every time, whether you need it or not. Green Robot AI gives you the right light for the moment.

Intelligent query routing

When you send a message, Green Robot AI analyses your request before it reaches any model. Simple, everyday questions — defining a word, drafting a quick email, converting units, brainstorming names for your cat — are routed to a lightweight, high-efficiency model that can handle them with ease. These models respond quickly and use dramatically less energy per request.
More demanding tasks — deep research, nuanced analysis, complex code, or multi-step reasoning — are automatically handed off to a top-tier frontier model with the horsepower to do them justice. You get the best available intelligence exactly when it matters, and only when it matters.

Why the difference is so big

The energy savings aren't just about using a smaller model. Today's most powerful models often perform extensive internal reasoning before they even begin writing a visible response — thinking through possibilities, evaluating options, and refining their answer behind the scenes. That hidden work can consume many times the resources of the final reply itself, and it often adds noticeable delay. For a straightforward question, all of that extra computation is wasted. By routing simple requests to an efficient model that answers directly, Green Robot skips the unnecessary overhead entirely — saving both energy and your time.

The Boost button

Intelligent routing gets it right the vast majority of the time, but sometimes you'll want more depth than the lightweight model provides. When a conversation is being handled by the efficient model, you'll see a Boost button at the bottom of the chat. Clicking it upgrades the conversation to the most capable model for the remainder of that chat and automatically regenerates the previous response so you get a richer answer straight away — no need to retype anything.
Think of Boost as a one-click upgrade: the conversation continues seamlessly, just with more firepower behind it. You stay in control of when the extra horsepower is worth the trade-off.

Manual overrides

If you'd rather not leave the decision to the router, the Quality slider in the AI Settings panel lets you lock in your preference. Set it to Faster to always use the efficient model, Smarter to always use the frontier model, or leave it on Auto to let Green Robot choose for you on a message-by-message basis.

Understanding the Sidebar

The sidebar is your control center for Green Robot AI. It gives you quick access to your chat history, AI behavior settings, account and billing info, and more. Below is a walkthrough of each section from top to bottom.

Billing and Payments

You can manage your subscription and payment methods at our billing portal, available in the Account section of the sidebar.

Every message you send to Green Robot AI costs a small number of credits. The exact cost depends on the length and complexity of the conversation — longer messages and smarter model settings use more credits, while shorter exchanges on the Faster setting use fewer.

Subscription credits

If you're on a paid plan, you receive a fresh batch of credits at the start of each billing cycle. These subscription credits are your primary balance and are always consumed first. Any unused subscription credits do not roll over — they reset when your next cycle begins.

Purchased credits

Need more than your plan includes? You can buy additional credits at any time in bundles of 10, 20, or 50 from the Buy more credits button in the Account section of the sidebar. Purchased credits never expire and sit in a separate balance that is only drawn from once your subscription credits have been fully used up for the current cycle.

Green Robot AI always uses your subscription credits before touching any purchased credits. They won't be spent as long as you still have subscription credits remaining.

Keeping track

You can check your remaining balance at any time in the Account section of the sidebar, where your subscription and purchased credits are displayed separately. If you'd like a more detailed breakdown of your usage history, head to the Billing portal to view invoices and transaction records.
