SigmaOS Airis

Airis reads the page you're on and answers questions about it in context, which makes it a hands-on AI browser assistant. You can start an in-browser AI chat with any website, search it using your own words, or ask it to explain a paragraph you didn't fully follow. Because it works from the page rather than a blank chat box, the context is already there.

When you have a loose question or idea, Look it up sends Airis to search the internet and assemble a starting point for you. It reads many pages at once and lets you ask follow-up questions, which is handy for early research on a topic you barely know. Think of it as an AI search assistant that hands you a starting point instead of a list of links.

Press S, or pinch out, and Airis acts as a website summarizer that condenses a site into a short interactive overview. From there you can ask any follow-up question without leaving the page. It turns a wall of text into something you can scan in seconds and then dig into only where it matters.

Because Airis sits in the browsing layer, it can use the page in front of you as its source. Ask it to find a specific number, define a term, or pull out the key points, and the answer stays tied to the page you're actually reading.

Paid tiers unlock more large language models, including Llama and Claude alongside GPT-4o, so you can pick a model that fits the task. Pro gives unlimited Advanced Airis on GPT-4o, while Max adds additional models and unlimited Look it up and summary usage.

Airis ships inside SigmaOS, which is built in native SwiftUI on the WebKit engine. As a true AI browsing companion, it sits next to the workspace, vertical tab, and split screen features rather than in a separate window. You also get Chromium extension support and Apple Keychain password protection in the same app.
