Long Summary

Long Summary is an AI summarizer tool that summarizes texts of any length at any output length you choose. Long Summary summarizes very long texts and files into outputs of any chosen length, avoiding the input and output limits of ChatGPT, Gemini and Claude.

Long Summary is a web based summarization tool built for documents that overflow the context windows of mainstream chatbots. The product's core claim is simple: ChatGPT, Gemini and Claude tend to struggle once input texts get very long, and they also resist producing lengthy summaries. Long Summary removes both constraints, accepting inputs of millions of characters and returning summaries sized to whatever length the user specifies, from a short overview to a detailed multi page analysis. Practically, a user pastes text or uploads a file, then chooses how long the resulting summary should be. The reasoning behind the long output option is that longer summaries preserve more of the source material, so less important information gets dropped along the way. The site pitches this against retrieval augmented generation for AI automation, arguing that feeding a long summary into a prompt gives more accurate results than assembling retrieved chunks. Documented use cases span market research on lengthy reports, legal texts where clauses and obligations matter, academic literature reviews, SEO content built from research papers, and general content creation for blogs and publications. Who it suits: businesses and professionals who need detailed digests of long reports, developers who want summarization inside their own products, and researchers or analysts drowning in PDFs. The developer API allows automated summarization of texts and files, which positions the tool as infrastructure rather than only a consumer app. It sits in the same territory as general purpose AI assistants but narrows the focus to one job and removes the length ceiling that makes those assistants unreliable on big inputs. Privacy is addressed directly: content is not published, and texts, files and summaries are stored only as long as processing requires before being securely deleted. The site does not publish pricing tiers, a free trial length, or a support channel beyond a chat widget, so buyers should confirm commercial terms directly before committing to volume use.
