Are the tools free? Do they upload anything?

Free and open source (MIT). Each tool is a single HTML file that runs entirely in your browser — nothing you type or paste is uploaded, logged or stored anywhere.

Where do the tools live?

On GitHub under github.com/mrsaynothing — one repository per tool, no build step, no dependencies. Fork them, restyle them, rip the wording out.

one question per tool, one HTML file per tool — nothing uploaded

Each tool here answers a single recurring question and gets out of the way: what is the exact git command for this mess, will this GGUF fit in this card before the 40 GB download. Every one is a static page you could save locally — the companion posts explain the arithmetic and the judgment behind each answer.
