Grounded, or silent.

For companies, reported financial figures come from tool calls over supported filed statements and retain their fiscal period. Fund facts use labelled fund-market data. When a question goes beyond the latest filing, Ask can use dated live-web sources and identifies them separately. If the available evidence does not support an answer, it is designed to say so rather than fill the gap from model memory.

Loading from SEC filings…

Nineteen years deep.

Most tools show you four or five years — enough to see a moment, not a business. Covered US-listed companies that report in USD can extend back through their 10-K filings for up to 19 annual years and 48 quarters, split-adjusted, with ratios and health checks computed from available data.

The screener is free. For everyone.

Screen 3,800+ US companies by real filed fundamentals — growth, margins, returns, valuation, dividends — with no account at all. The depth behind each result is the product; the door is open.

Ask the AI analyst

Your questions, answered with the source class shown.

Ask about companies, ETFs or mutual funds — compare stock fundamentals, inspect a fund's costs and holdings, or rank eligible funds over 3 months, 1 year and 3 years. Company figures come from filings; fund figures come from fund market data.

Your portfolio, read by AI

A calm dashboard that does the reading for you.

Know what changed in a supported filing

A cited first pass for your research workflow.

When a supported company files, the Filing Change Monitor reads its latest 10-K, 10-Q or 8-K and produces a first-pass view of material changes — including available year-over-year figures and cited guidance, risk-factor and demand language — ranked by materiality.

It turns a manual first pass through new filings into a watchlist workflow. Financial comparisons are computed from available filing data; the AI summarizes the cited evidence rather than substituting model memory. On Power and Desk.

See what tracked managers reported

27 manager portfolios from SEC Form 13F filings.

Qualifying institutional investment managers report covered holdings on Form 13F after each quarter. We turn available filings for Warren Buffett, Bill Ackman, Michael Burry, Seth Klarman and 23 more into readable snapshots — reported positions and weights, plus share-count additions, increases, decreases and removals versus the prior quarter. These are delayed disclosures, not live portfolios or trade signals. Free to browse.

On Pro, an AI analyst summarizes the largest reported changes and concentration. Holding weights and quarterly share-count changes are computed from available 13F data; the narrative is written from those results.
