Your Excel model is a source we can cite.
Drop in your existing model. Kerns reads sheets and cells, writes back when you let it, and cites the cell it used the same way it cites a 10-K page. A memo footnote can point at Model · Q3 Numbers!C5 — click the chip and the workbook opens to that cell, highlighted.

One framework. Twenty companies. Zero copy-paste.
A Kerns framework is a reusable analytical recipe — the rubric an analyst already runs, written down once and applied across the coverage list. The outputs are individually defensible; the framework is centrally maintained.

The model knows which line you changed.
Most AI tools restart the conversation when you push back. Kerns reads your edits in-place. Redline a paragraph, attach a counter-document, ask for a re-pull — Kerns understands which sentence you mean and which line in the draft you're refining.
Your coverage list, watched while you sleep.
Pick a coverage list and a framework. Always-On runs it on a cadence — when a new 10-Q drops, when an earnings call lands, when a thesis-relevant news item hits — and emails you the deltas. Every flagged item is a real Kerns answer: cited, traceable, ready to drop into a memo.
- WMTDELTA →FY25 Q3 10-Q filed — ROIC ticked to 14.6%.Up from 13.7% (FY24). Reconciles to your ROIC framework's threshold check.
- COSTTRANSCRIPT →Earnings call — capex guide raised.Management said 8–10% range becomes 10–12%. Flagged because your memo cited the prior range.
- KRFORM 4 →Insider transaction — CFO sold $2.1M.Form 4 filed; first sale in 18 months. No new disclosure language.
Audit the AI the way you'd audit a junior.
Every Kerns answer ships with a full reasoning trace — the documents read, the calculations run, the assumptions made — whether you triggered the run yourself or Always-On did it overnight. You can read it the way you'd read a junior analyst's bench notes, and you can challenge any step.
