The tool
An HTML stripper for a two-layer export problem
Gemini structures most answers as a bolded term, a short explanation, then indented sub-points, and every layer of that structure is genuine markup: a bold tag, a nested list tag, before it ever reaches your clipboard. Export the same answer to Docs and a second layer of styling wraps around the first, since a Google Docs document represents bold text and nested lists in its own way.
This tool strips both layers in a single pass, along with attributes, script and style blocks, and decodes a handful of common entities. The pass runs client-side, in JavaScript, in your own browser, with no request sent to a server, which is also why there is no run limit.
