FAQ

Common questions

Is this summarizer actually free?

Yes. 5 summaries per day with no signup. Sign in (free account) for 50/day. The free tier handles most everyday summarization needs.

How long can my input be?

5,000 words per summary on the free tier. 25,000 words signed in. For longer documents, summarize in sections.

Do you summarize PDFs and YouTube videos?

Not yet — current version handles pasted text only. PDF, URL, and YouTube modes are on the roadmap. For now, copy the article text or transcript and paste it in.

How accurate is the summary?

TextSight's summarizer is built on Claude Sonnet 4. Factual claims, names, and numbers are preserved exactly. For high-stakes work (medical, legal, financial), always verify the summary against the source.

What's the difference between the four lengths?

Sentence: 1 sentence (~30 words), captures the main point. Bullets: 3 key takeaways as bullet points. Paragraph: 60-100 words, balanced overview. Detailed: 200-280 words, multi-paragraph for in-depth content.

Will the summary read as AI?

It might — most LLM-generated summaries do. If you're using the summary in your own writing, run it through TextSight's free Humanization Score detector to see how human it reads, then paraphrase if needed.
