Deep Tab Search: Search Tab Content

Search open tabs by title, URL, or full page text. Find words and passages inside tab content, privately and locally in Chrome.

DeepTab Search lets you search inside the actual content of all your open browser tabs — not just titles and URLs. Find that paragraph, heading, or keyword you remember seeing somewhere. FEATURES - Full-text content search across all open tabs - BM25 ranking (same algorithm used by search engines) - Fuzzy matching for typo tolerance (Elasticsearch-style AUTO fuzziness) - Synonym expansion (ai → artificial intelligence, ml, llm, and more) - Highlighted snippets showing match context - Relevance scoring (percentage shown per result) - Keyboard navigation (Arrow keys + Enter to switch tabs) - Background indexing — tabs are indexed automatically as they load - Light and dark theme (or follow your OS) - Configurable settings: indexing, search boosts, custom synonyms, excluded domains HOW IT WORKS The extension reads the visible text on each open tab (up to 60KB per page) and caches it locally in your browser. When you search, it matches your query against this cached content using word matching, synonym expansion, fuzzy matching, and BM25 term-frequency ranking. KEYBOARD SHORTCUT Press Alt+S (Option+S on Mac) to instantly open the search popup. Arrow keys to navigate, Enter to switch to a tab. PRIVACY Everything stays local. Page content is extracted and cached in your browser's IndexedDB. No data is sent to any server. The extension only reads pages you already have open.
