Instead of chunking PDFs into a vector database, it builds a hierarchical tree index and lets an LLM reason through that tree to return answers cited to pages or blocks. It is offered as a chat workspace, a developer API/MCP, and an open-source local mode.","category":"AI & Automation","decision_record":{"best_for":"Financial, legal, regulatory and research teams that need auditable answers over long professional documents such as filings, contracts and reports.
