Questions

›Component or full URL?

"Component" encodes every reserved character (for a single query value). "Full URL" keeps characters like ":" and "/" so the URL stays usable.

›Is my data uploaded anywhere?

No. This tool runs entirely in your browser, and Rounder never sends what you type or drop in to a server, ours or anyone else's. Once the page has loaded, along with any AI model the tool uses, it even works offline.
