Free AI Text Summarizer: Automatically Summarize Your Documents

Our automatic text summarizer uses artificial intelligence (TF-IDF extractive algorithm) to generate concise and relevant summaries of your articles, reports, studies and long documents. Instantly condense your texts by 60-80% while retaining essential information.

How Does Automatic Summarization Work?

Our AI summarizer uses an extractive approach based on the TF-IDF algorithm (Term Frequency-Inverse Document Frequency). This method statistically analyzes your text to identify the most important sentences containing essential keywords. Unlike abstractive summaries that rephrase, our tool directly extracts the most representative original sentences, ensuring fidelity and accuracy.
