 Open Index is a large-scale web text dataset built from [Common Crawl](https://commoncrawl.org). Every page goes through a pipeline that extracts the main content from raw HTML, converts it to clean Markdown using [trafilatura](https://github.com/adbar/trafilatura), and packages the result into Parquet files with full WARC metadata preserved.
 
-The dataset currently includes crawl **CC-MAIN-2026-08** with **18,373,704 documents across 949 shards**. We plan to add more snapshots over time.

 The big win is the HTML → Markdown step: trafilatura strips all tags, scripts, styles, navigation, and ads, keeping only the main content. This cuts 2.2 TB of uncompressed HTML down to 82.9 GB of markdown — a **98.3% reduction** — before any file-level compression is applied. Parquet with Zstd level 19 then compresses the markdown a further 68.2%.
 
-End to end: ~769.2 GB of raw gzipped WARCs becomes **26.3 GB of Parquet** — a **96.6% total reduction** — containing 18,373,704 clean markdown documents.
