About grepcent

grepcent is a cheap, static financial knowledge site built for both human readers and LLM retrieval. Pages are generated as plain HTML with the useful text and tables in the markup.

Data Sources

grepcent uses license-free public-domain U.S. government sources: SEC EDGAR and SEC companyfacts for company filings and fundamentals, plus FRED series sourced from agencies such as BLS, BEA, Census, HUD, the Federal Reserve, Treasury, and OMB.

How It Is Built

The site is prebuilt into static files and served from S3 and CloudFront. Figures are our own static, CSP-safe SVG rendered at build time from the same numbers printed in the page tables — readable by machines, with no third-party chart script and no opaque canvas.

Editorial Posture

grepcent is descriptive. It assembles public facts, source links, SIC hierarchy pages, computed tables, and educational examples. It does not publish recommendations, forecasts, ratings, or investment advice.

How grepcent Stays Honest

grepcent is built to be honest by construction, not by spot-checking after the fact. When a page can only be assembled correctly for some of its subject matter, grepcent leaves the rest out rather than guessing — an honest gap is a feature, a confident wrong number is a defect. Concretely:

• Numbers are verified, never authored. Every figure is templated from SEC companyfacts-derived facts that grepcent has already validated (period, units, currency, sanity invariants); a value that can't be verified is omitted, not estimated.
• Comparisons are computed, not asserted. Any ranking or head-to-head number is calculated in code from those verified facts — grepcent never writes a comparative claim in prose.
• Narrative is quoted, not paraphrased. Where a page describes what a company said, the supporting text is a verbatim, source-linked quote from that company's SEC filing, string-matched to its citation. A label that isn't faithfully supported by its quote is dropped.
• The publish check is the audit. The same code that decides a claim may appear is the code that detects whether it is supportable — there is no separate "looks fine, ship it" path. Fail-closed gates abort the build on a violation (for example, the site refuses to ship a page containing a legacy chart canvas).

The result is descriptive data and cited filer text, with honest gaps where the source doesn't support a claim. This is a methodology, not a promise about any individual number; always confirm against the linked SEC source. See the Disclaimer.

Machine-Readable Data

Every page's useful text and tables live in the HTML markup, so an LLM can read a page directly without executing scripts. Each page also has a plain-Markdown twin (append .md), each company offers verified financials as downloadable financials.json and financials.csv, and llms.txt maps the site for crawlers.

Analytics / Privacy

grepcent uses Google Analytics, a third-party Google service, to measure site usage. Google sets cookies and receives standard analytics data (such as IP address, device, and pages viewed), processed under Google's privacy policy (https://policies.google.com/privacy). grepcent itself has no login and collects no account data.
