AI Keyword Extractor Pro
Extract the most important keywords, phrases, and topics from any text. See ranked results with frequency data and a visual word cloud.
How It Works
The AI Keyword Extractor uses a statistical NLP approach to identify the most meaningful terms in your text. The process begins with tokenization — splitting the text into individual words and contiguous word pairs (bigrams). A comprehensive stop word list then filters out common, low-information words to ensure only meaningful content words remain.
Each remaining word and bigram is counted for frequency, and results are ranked from most to least common. The word cloud provides a visual representation where keyword size corresponds to frequency, making it easy to spot dominant themes at a glance. Bigram detection captures multi-word concepts like "machine learning" or "climate change" that carry more context than single words.
Everything runs in your browser — your text is never uploaded to any server, ensuring complete privacy.
