Summarize Your Text
What Is a Text Summarizer?
A text summarizer condenses long content into its most important points. It saves you from reading entire articles, research papers, or reports when you only need the key information. Unlike skimming or speed reading, a summarizer captures the essential meaning without missing critical details.
Two Summarization Modes
Selects the most important sentences directly from your text and displays them in order. No data ever leaves your browser - 100% private. Great for sensitive documents, contracts, and personal content.
Uses Llama 3.3 70B to rewrite the key information in fresh, coherent language. Produces a natural-sounding summary that connects ideas smoothly. Your text is sent to our AI provider for processing.
Why Not Just Ask ChatGPT?
AI chatbots hallucinate. They often add facts that don't exist in the original text, miss critical details, or produce inconsistent summaries. Our extractive mode guarantees every sentence in the summary came from your original text - nothing added, nothing invented. Our AI abstractive mode uses a focused system prompt designed for accuracy, not creativity.
How the Scoring Works
The extractive mode scores each sentence by analyzing word frequency patterns. Sentences containing words that appear frequently across the text rank higher. A position bonus gives slight preference to introductory sentences. You control how much to keep using the summary length slider.
Frequently Asked Questions
What is the difference between extractive and abstractive summarization?
Extractive picks existing sentences from the original text - nothing is rewritten, so accuracy is guaranteed. Abstractive generates new sentences that capture the meaning, which reads more naturally but may occasionally miss nuance. Use extractive for precision, abstractive for readability.
Is my text stored or shared?
In extractive mode, your text never leaves your browser - 100% private. In AI abstractive mode, your text is sent to Groq's API for processing only. We do not log, store, or share any text you submit.
How long can the input text be?
Extractive mode handles any length your browser can process (tested up to 100,000 words). AI abstractive mode works best with texts up to 10,000 words due to the AI model's context window limits.
Does the summary preserve meaning?
Extractive mode preserves exact meaning by using the original sentences. AI abstractive mode preserves the core message but may rephrase details. Always verify important summaries against the original text.
Can I use this for academic papers?
Yes. Use extractive mode to get the key sentences from research papers, or abstractive mode for a coherent paragraph summary. Both help you scan multiple papers quickly during literature reviews.
What language does the tool support?
Extractive mode works with any language that uses sentence punctuation (periods, question marks, exclamation marks). AI abstractive mode works best in English but handles many major languages.
Why have an extractive mode if AI is smarter?
AI is not always smarter for summarization. AI models hallucinate - they add invented facts, especially with longer texts. Extractive mode guarantees 100% factual accuracy because it uses the actual source sentences. For legal, medical, or financial documents, this matters.
How do you determine which sentences are important?
Our algorithm scores each sentence by the frequency of its words across the full text, giving higher scores to sentences with more common important terms. A slight position bonus favors opening sentences. The result is objective, reproducible, and deterministic.
