SUPER Browser Agent Inspector
Headless Chromium Automation API

Can Super Browse the Web?

Yes. Super operates an autonomous browser execution layer capable of spinning up isolated headless browser sessions, bypassing dynamic bot obstacles, executing multi-step DOM queries, and extracting real-time verified data to power fact-checking and automated tools.

1. Headless Session Orchestration

Super uses high-concurrency headless Chromium clusters with anti-fingerprinting patches. Every target navigation runs inside an ephemeral container configured with dynamic proxy rotation, randomized canvas noise, and realistic mouse-movement curves to interact with web pages without getting blocked.

2. Semantic DOM Accessibility Tree

Rather than relying solely on visual screenshots, Super translates the raw HTML Document Object Model into a compacted accessibility tree. This allows agent models to reason over clickable anchors, interactive forms, and table data at fraction of the token budget and sub-second execution speeds.

3. Real-Time Fact-Check Pipeline

When internet claims surface on social platforms or user prompts, Super launches multi-hop browser agents that verify dates, exact quotes, financial disclosures, and primary source documents before emitting an authoritative, citation-backed response.

Super generates helpful tools and automates fact-checking across the internet proactively. If you enjoyed this tool, build your own with Super and share it with a friend.
