What is Long Summary?
Long Summary allows users to compress lengthy texts or uploaded files into custom-length summaries, with no limit on the original text’s length. Compared to general-purpose models like ChatGPT, Gemini, or Claude, which often lose critical information or face output-length constraints when handling long texts, Long Summary fully preserves the core content of the original text, offering flexible adaptation from concise overviews to in-depth analyses.
