Calculators expose their assumptions. Inspectors parse the text you supply; they do not send email or fetch your video streams. Each tool includes examples, limitations and a route to the next useful task.
Provider links and optional offline kits are presented separately from results. The tools remain free. No customer outcome, saving or revenue is implied by a calculation.
