Halcyon helps energy professionals find, monitor, and analyze authoritative energy information. We offer two solutions: Halcyon Platform and Halcyon Data Subscriptions

Search

Halcyon Search lets you set criteria — such as a document’s publisher or relevant keywords — and returns a list of all matching documents from the millions within Halcyon’s Data Catalog. You can read and download these documents, and can also see a list of the dockets associated with those documents.

Queries

Halcyon Query is a natural-language question or prompt that generates a cited response from Halcyon’s data catalog. For example, you might ask “What is the history of Green Mountain Power’s battery partnership with Tesla?”, and Halcyon will compose a long-form answer with citations from the source material.

Alerts

Halcyon Alerts enables you to proactively monitor relevant information with AI-powered analysis surfaced from the documents that matter most to you. With one click on the “Create Alert” button, you can customize an email alert that will automatically send new documents matching your current search filters.
