What to include in a bug report
- Which tool, and its full URL — for example tools/json-formatter.html.
- What you expected to happen and what happened instead.
- Your browser and version, plus whether you were in dark mode.
- A snippet of the input you used — please redact anything private, since nothing here stores your data for you.
Tool requests
If something is missing from the shelf, describe the job it should do in one sentence. Single-purpose tools that run entirely in the browser are the easiest to add; anything needing a server or an API key will not fit this project.
