datajoi

Grab tables from any page and query them instantly with SQL — private, in-browser analytics that never leaves your machine.

SQL on any webpage. datajoi turns the page you're looking at into queryable data. Click tableGrab and every HTML table on the page becomes a typed DuckDB table you can query with real SQL — joins, aggregates, window functions — in a chat-style side panel: your query is the message, the answer comes back as a DataStory summary with an inline chart. KEY FEATURES • tableGrab — one click imports every table on the current page • Chat-style flow — ask in SQL, answers stack up as a conversation • DataStory summaries with inline bar charts, computed locally from your result (deterministic — no AI, nothing leaves your machine) • File import — CSV/TSV, Parquet, JSON/NDJSON, and Excel • Full DuckDB SQL with schema-aware autocomplete • Results grid built for 100k+ rows; export CSV or copy to the clipboard • Saved queries and history, restored across restarts • Dark mode PRIVATE BY DESIGN The DuckDB engine is compiled to WebAssembly and ships inside the extension. Your data is processed on your machine and stored in your browser's local storage. No servers, no account, no analytics, no telemetry — nothing is uploaded, ever. HOW TO USE 1. Pin datajoi and click its icon on any page with tables. 2. Hit "tableGrab this page" and pick the tables you want. 3. Query them with SQL. Export what you need.
