Why AskSia
The article summarizer that doesn't make things up.
Generic chatbots paraphrase articles without showing where claims came from. AskSia cites every line back to the exact passage in the source.
Cited to the exact passage
Every line of the summary carries a [N] marker. Hover to see the exact paragraph highlighted in the source article. Click to jump into the article at that point. No hallucinations to chase down later.

FAQ
Common questions about article summarizing.
How do I summarize an article with AskSia?
Paste the article URL into AskSia, or upload the saved file (PDF, DOCX, MD, TXT, RTF, EPUB). AskSia reads the article, builds a passage-level citation index, and returns a clean structured summary in seconds. Every line of the summary carries a [N] citation marker that, on hover, reveals the exact source passage highlighted.
What article formats does AskSia support?
AskSia handles public article URLs (news sites, blogs, magazines, academic blogs, journal articles with public access) and uploaded article files in PDF (native and scanned), DOCX, DOC, MD, TXT, RTF, and EPUB. You can mix URLs and uploads in the same session.
Can AskSia summarize paywalled or login-only articles?
AskSia reads public articles directly from URLs. For paywalled or login-only articles, save the article as a PDF or DOCX (most browsers and reader apps support this) and upload the file. AskSia handles the upload the same way and produces the same cited summary.
How accurate is the summary, and can I trust it?
Every claim in the summary is grounded in a [N] citation that links to the exact source passage. You can hover any citation to see the original passage highlighted, or click to jump into the article. The summary will not include any claim it cannot trace back to the source, which makes it more reliable than generic chatbot summaries.
Can I summarize many articles in one session?
Yes. AskSia supports up to 100 articles in a single study session. Useful for reading-list synthesis, news comparison across outlets, lit reviews, and research papers. Ask cross-article questions like 'which articles support X?' or 'where do these pieces disagree?' and receive a synthesized answer with per-article citations.
Can AskSia summarize articles in other languages?
Yes. AskSia summarizes articles in 40+ languages and detects the source language automatically. You can also translate the summary at the same time, so a Spanish, Mandarin, or French article can be read in English alongside the original. Useful for international students and language-learning programs.
Can I turn an article summary into study materials?
Yes. One click turns the summary into definition flashcards, a concept-check quiz, a study guide, or a visual concept map. Each card and question links back to the original article passage via the same citation system. Useful for class prep, exam review, and discussion-board posts.
