Download Xerolas
Install Xerolas on Windows, macOS, or Linux and start using desktop-wide AI screen intelligence right away. On Ubuntu, use the App Center / Snap Store install for the cleanest experience.
Setup
Xerolas is open source and safe to inspect. You can bring your own provider key, or use an optional Xerolas Cloud platform key for a simpler managed path.
Add your own Anthropic, OpenAI, Gemini, or OpenRouter key in Settings. Xerolas stores it locally with OS encryption when available and sends captures directly to that provider.
Paste an opaque xlo_live_... key issued by Xerolas. The Cloud gateway checks quota, rate limits usage, and uses managed AI providers behind the scenes.
How it works
Capture, understand, and move on without switching apps or uploading files by hand.
Hit Ctrl+Shift+Space from anywhere on your desktop, whether you are in your editor, browser, design tool, terminal, or a document.
A full-screen overlay appears so you can drag across any area of any window: code, an error message, a chart, a design, or a block of text.
Xerolas analyzes the selected region and can add live web context when the answer needs current information. When web search is used, source links appear in the result panel.
The result panel appears beside the selected region so you can read, copy, dismiss, or rerun the same capture through a different mode without repeating the screenshot.
Works System-Wide
Xerolas works across every app and window on your desktop: VS Code, Figma, Chrome, Excel, Slack, terminals, PDFs, and more.
BYOK Or Cloud
Add your own provider key, or paste a Xerolas Cloud platform key issued from Xerolas. Either way, the desktop app never ships a public provider secret.
Prompt Modes
Describe what is visible, extract text, explain code, translate, summarize, or answer the most useful question implied by what you selected.

Features
Xerolas stays focused on one job: helping you understand anything visible on your screen as quickly as possible.
Use Xerolas across every app and window on your desktop, not just inside one browser tab.
Press Ctrl+Shift+Space from anywhere to start a capture without hunting for the app window.
The selected region is captured natively and sent directly for analysis without a manual file picker.
Describe, extract text, explain code, translate, summarize, or answer the most useful question from the selected region.
Your last 10 captures and results stay available locally so you can re-open them without repeating the capture.
Xerolas checks for updates in the background so the installed desktop app stays current without manual downloads each time.
Comparison
Browser lens tools are useful inside one tab. Xerolas brings that same kind of screen understanding to the whole desktop.
