Everything above stays free, and stays MIT. Sold separately, MrkEditor is the other half: counting, summarising, seeing time, and searching across folders — the things you currently leave the editor to do. Numbers below are measured on the shipping code (M4 Max, August 2026), not estimates.
Count by value — what sort | uniq -c | sort -rn does, on a column or a key=value field. 3.40 s over a 10 GB, 86,420,337-line log. Double-click a row and the document filters down to that value
Column stats — every column of a CSV in one pass: type, blanks, distinct, min/max, sum & average. 4.78 s for all 30 columns of a 1.18 GiB CSV (5,816,534 data rows). A column is only called numeric when every row reads as a number
Time histogram — when did it spike? 3.18 s over a 10 GB, 67,156,671-line log. Filter to errors first, then look at time. Lines without a timestamp are counted separately, never dropped. Drag across the bars and the document narrows to that window
Search across folders — 3.14 s for one literal across a single 10 GB log, on par with ripgrep. What ripgrep does not do: click a hit and the file opens at that line, and Shift-JIS / EUC-JP files are detected per file and read correctly

MrkEditor is a one-time purchase through Polar. The free app keeps the same Analyze menu in the same place; choosing an item explains what MrkEditor adds.
