Lab
Three tools I use often enough to keep close. The microphone stays off until you press the button. The token count is an estimate. The contrast checker uses WCAG 2.2.
Tuner
Play a note. The tuner shows the nearest note, the octave, the distance in cents, and the frequency. It asks for the microphone only after you press the button.
Tokens
Paste text, set a price, and get a rough input-token count and cost. The estimate counts words and punctuation; a real tokenizer will split them differently.

This is a word-and-punctuation estimate. Real tokenizers split text differently, especially code and Vietnamese. Use it for a rough budget, not a bill.
Contrast
Pick a text color and a background color. The checker shows the WCAG ratio and the AA and AAA thresholds for normal and large text.
The quick brown fox jumps over the lazy dog.
Small text has to clear a higher bar than a heading.
