FAQ
How are the metrics defined?
Total includes spaces/newlines; no-spaces strips whitespace; Chinese counts CJK range; English words count consecutive letter runs; number groups like 3.14 count as one.
What is UTF-8 byte count for?
Many APIs and databases limit by bytes; a Chinese char usually takes 3 bytes, so this helps enforce byte-length limits precisely.
Will my data be uploaded?
No, all counting runs locally in real time.
