Frequently asked questions
How is this different from word frequency?
Frequency tells you which words appear most often, including filler. This tool extracts the topic-bearing nouns and noun phrases — what the text is about. For raw counts, use Text Frequency instead.
What format is the output?
JSON, so the extracted keywords are easy to feed into other tools or scripts.
Does my text leave my browser?
No. The extraction runs entirely on your device; nothing is uploaded.
What kind of input works best?
Plain text prose. The more coherent the writing, the more meaningful the topic nouns and phrases it surfaces.
Will it pick up multi-word phrases?
Yes — it captures noun phrases, not just single words, so terms like compound topics come through.
