What It Is

Corners positions itself as “Document Intelligence Maps”: it turns large document troves such as FOIA public records, court filings, and leaked archives into intelligence maps. Its core value is not ordinary summarization, but extracting geographic factual claims from documents: who appeared where and when, what happened, and then mapping those events onto a filterable map. The Epstein Atlas example shown on the site says it scanned 32,472 documents and generated 3,167 events across 466 locations, with each map point linked back to the source document.

Core Capabilities

The workflow consists of four steps: Triage, Extract, Resolve, and Map. It first filters out documents that do not contain specific location relationships, then extracts locations, dates, people, events, and verbatim quotations. Next, it matches fragments against an event database, merges duplicate events, and accumulates evidence. Finally, it geocodes the results and publishes the map. Corners emphasizes that “Nothing is invented,” and provides confidence scores and evidence citations for events, making it suitable for investigative and legal work that requires an auditable trail.

Pricing and Integrations

The website does not disclose plans, unit pricing, free quotas, or trials; it only provides a contact form. Target use cases include FOIA/public records, legal discovery, investigative journalism, research/academia, and “Build your own instance,” but there is no information about APIs, SDKs, third-party system integrations, self-hosting options, or delivery timelines.

Pros and Cons

Its strength is its focused use case, especially for discovering networks of locations, people, and events across thousands of pages of PDFs, court records, and archives. The output can be traced back to the original text, reducing the risk of AI hallucinations. The downside is the lack of key disclosures: there is no explanation of the underlying models, accuracy, human review process, privacy compliance, Chinese-language support, or data deletion policy. For sensitive materials such as legal discovery data or leaked archives, these factors directly affect procurement decisions.

Best Fit and Access from China

Corners is better suited to investigative journalists, lawyers, investigators, and research institutions that need to quickly turn document repositories into evidence maps, rather than everyday office users. The website text does not make clear whether it is accessible from mainland China, and payment methods are not disclosed. If access, compliance, or Chinese-language processing is limited, alternatives include Maltego, Relativity, Everlaw, or building a custom workflow using large language models together with OCR, entity extraction, and GIS tools.
