Local processing

Your input stays in this browser. Drafts are kept in page memory while switching tools, and disappear on reload.

Text is limited to 1 million characters. Regex runs in a worker, capped at 200,000 characters, 1,000 matches and 1.5 seconds. Inputs above 100,000 characters use manual refresh.

The first page load and on-demand modules require network access. A complete offline cache is not included.
