About Castling Financial
Built for people who read the filings
Castling turns EDGAR filing data into clear, comparable financial insight for investors, analysts, and anyone curious about how companies perform: annual fundamentals, reported segments, and material company updates.
Search a ticker, scan trends across years, and drill into the statements behind the numbers. Fast, clean, and always two moves ahead.
Research shouldn't feel like a chore
It started with frustration. Pulling the numbers you actually need meant bouncing between Google Finance, Yahoo Finance, and a dozen other sites, each with slow, clunky interfaces that got in the way. Castling exists to make filing data fast, clean, and trustworthy to reach.
Ground answers in filing data
General-purpose models often invent or misstate financial figures when they rely on memory alone. Asking them to scrape the web in chat is not a reliable way to get accurate filing figures either.
Answers cite published data
Castle AI and MCP connectors pull from Castling's filing-backed warehouse — KPIs, statements, screens, compares, and material 8-Ks — so answers can cite published data instead of guessing.

Retrieval reduces risk, not to zero
Grounding answers in filings cuts hallucination risk sharply, but it does not eliminate it. Every figure carries its source so you can check the filing yourself.
Data accuracy
Filings we cover today
Source of truth
Castling starts with what companies file on EDGAR. Statement cells map to XBRL tags, periods, and units. Overview metrics come from annual filings with clear provenance on every value that is present. Segments break revenue and other metrics across reported business, geography, and product members. Company Updates shows material Form 8-Ks from EDGAR in an in-app reader, not a market news wire. We do not use third-party vendor estimates.
Consistent over time
The Overview organizes filing data into comparable metrics across fiscal years. When a number is present, you can see whether it was reported from a tag, filled from a canonical field, derived from filing sources, or adjusted for splits. When it cannot be sourced from filings, it stays blank rather than guessed.
Transparent limits
We aim for high accuracy, but perfect coverage across every filer, metric, and year is not realistic in automated financial data. Companies use different tags, restate prior periods, and file amendments. When something looks wrong, our pipeline is built for traceability, so we can find whether the issue is in the filing, our ingest, or our presentation, and fix it. If something looks wrong on your data, we welcome a report as it helps us improve.
