ZapToolsText Summarizer & Rewriter
Smart extractive summarizer, simplifier and writing polisher — free, private, instant.
How it works
This is a smart extractive summarizer — it scores every sentence by keyword frequency and position in the text, then keeps the highest-scoring sentences in their original order. Nothing is uploaded: all processing happens in your browser.
The three modes
Summarize condenses long text to its most important sentences. Simplify swaps formal or complex words for plain everyday alternatives and breaks up very long sentences. Improve fixes double spaces, stray capitalization, missing sentence capitals and common typos.
Frequently Asked Questions
How does the summarizer work?
It scores every sentence by keyword frequency and position, then keeps the top-scoring sentences in original order. Nothing is sent to a server.
What does Simplify mode do?
It replaces formal or complex words with simpler everyday alternatives from a built-in dictionary and splits very long sentences.
Is my text uploaded anywhere?
No. All processing happens locally in your browser — your text never leaves your device.
Can it rewrite like AI paraphrasers?
It improves and simplifies deterministically. For deep creative rewriting use a large language model; this tool is best for fast, private summaries.
