Inline context for every article, without leaving the page

Rabbitholes is a new Chrome extension that shows AI-generated explanations beside highlighted text, so readers can understand terms without leaving the page.

It also suggests related rabbit holes, supports follow-up questions, and returns source-enriched answers with clickable source chips.

The extension sends requests directly from the browser, uses Claude Haiku 4.5 and Brave Search, and avoids an intermediary server.

Built with Manifest V3 and shadow DOM, it stores API keys in chrome.storage.sync and says it collects no telemetry.
