What's new

New features and improvements to 13F Pro, newest first.

October 2026

  1. Improved

    Busy company pages answer faster

    when several people open the same company at once, its figures are now built once and shared instead of being rebuilt for each reader.

  2. New

    Reports price on the right share count

    a company that split its stock or issued shares since its last annual report is now valued on the shares it actually has, and the page names the count it used.

  3. New

    Faster filing proofs

    opening the filing behind a number answers in seconds, and when SEC is slow it hands over the filing link instead of hanging.

  4. New

    See how a score is built

    the quality score opens every factor's.

  5. New

    Prove a score

    every factor on a company's quality score opens the figure it ranks, the formula behind it, and the filed quarters underneath.

  6. New

    Prove any number

    click a figure or a ratio on a company page to see the computation, every input as filed, and the cell boxed inside the filing it came from.

  7. New

    Capital spending, fiscal years and share classes

    capex now reads.

  8. New

    Scores read the filings

    quality scores are now computed from the same filings tables the company page shows, so a score and the numbers beneath it can no longer disagree.

  9. New

    Every number traced to its filing

    Key financials now link each figure to the SEC filing it came from.

  10. New

    Nightly filing check

    Every figure on company pages is now traced to the company's SEC filings every night.

    All eight featured stocks on the ad page now show their live AI score.
