Long Summary - 2026 Pricing, Features, Reviews & Alternatives

Long Summary is a cloud-based AI text summarization web application that processes input texts and file uploads of unlimited length, including documents with millions of characters, and generates summaries with no restrictions on output length. Designed for students, professionals, content creators, developers, and businesses across content publishing, academic research, and software development, it addresses a core limitation of standard AI summarization tools: input and output length caps. Summary length is fully configurable, from brief overviews to detailed, long-form analyses.

Beyond standard summarization, Long Summary supports long-form article generation from large source texts such as research papers or custom datasets. It also supports prompt augmentation, allowing long data summaries to serve as an alternative to Retrieval-Augmented Generation (RAG) for improved accuracy in downstream AI workflows. File upload support accommodates lengthy documents and reports without requiring manual text extraction. A dedicated API enables developers to integrate automated summarization of texts and files directly into their own applications and workflows.

Content is not published or retained after processing. Texts, files, and summaries are stored temporarily during processing only and are securely deleted upon completion, making Long Summary suitable for organizations with privacy or confidentiality requirements.
