Harvest excerpts from your corpus (without AI flattening)
Corpus is a specialized tool designed for users who need to efficiently recall and cite information from their own collection of documents. Unlike traditional LLMs that often struggle with source citation and tend to produce flattened or generalized summaries, Corpus offers a focused solution by allowing users to upload files within projects and perform semantically matched searches. This approach makes it a powerful asset for researchers, writers, and knowledge workers who require precise excerpts from their personal or organizational corpora. Its emphasis on maintaining source integrity while enabling deep, focused searches distinguishes it from generic note-taking or AI summarization tools. Corpus enhances productivity by providing a straightforward way to access relevant information without the complexities or inaccuracies that sometimes accompany AI-generated content.
