How this service works
Summarize text into its key sentences with extractive frequency scoring, returns top sentences in original order plus compression stats. text summarization, summarize text, tldr, article summary, key sentences, extractive summarizer Accepts payment on Base or Solana — either network works.
Output
Returns the top-ranked sentences from the input text in their original order, along with compression statistics such as the number of sentences extracted, total input sentence count, and compression ratio.
Example use cases
Example prompt
“Can you summarize this article for me and pull out the most important sentences — here's the full text: 'Researchers at MIT announced a breakthrough in quantum computing today, achieving a 99.9% gate fidelity using a new error correction technique. The team spent five years developing the approach, which relies on topological qubits. Experts say this could accelerate practical quantum computing by a decade. Funding came from DARPA and several private investors. The results were published in Nature this morning.'”
