The tool
A line break remover for a nested, two-pass rendered answer
Gemini's answer format structures most replies as a bolded lead-in followed by indented sub-points, and every level of that structure renders as a genuine line break rather than a sentence that merely wraps. Export the same answer to Docs and it is rebuilt a second time inside an actual document, with its own spacing conventions layered on top of the first.
This tool replaces every line break with a space, collapses the resulting runs of spaces to one, and returns the input as a single continuous paragraph, regardless of which rendering pass produced the breaks. The pass runs client-side, in JavaScript, with no upload and therefore no run limit.
