Show the evidence
Research views expose the trades, filings, prices, and assumptions available for inspection. Model output and inference are labeled as such.
Finance should be
testable, not told.
Schmatz turns a plain-language question into a source-aware, backtested answer across five years of US equity history. Built for the curious — students, independent investors, and aspiring analysts.
Most of finance reaches you as a conclusion — a hot take, a headline, a number with no lineage. You’re asked to trust, rarely to check.
Schmatz is the opposite. It’s a place where you can ask, “what would have actually happened?” — and get an answer you can interrogate, line by line, source by source. Type an idea in plain language; it runs a historical backtest against the available research corpus — five years of prices, filings, and classified market events where coverage permits — and returns a result with evidence you can inspect.
Every figure traces back to where it came from. Nothing is a recommendation. It’s a lab, not a tip sheet — a way to learn how markets behave by testing ideas against what they really did.
What we hold to
Three commitments that shape every screen.
Paper, not advice
Results are historical and illustrative — backtested net of costs. Nothing here is a recommendation to buy or sell.

Who’s behind it
A finance + information-systems student building Schmatz in the open — tired of taking finance on faith.
Thomas Schmatz

I’m building Schmatz solo as a personal research project — the research desk I wished I’d had as a student. The whole thing runs on a single VM I pay for myself; everything you see was built by hand. Honest about its limits, generous with its sources.
