Turn two P&L columns into MD&A-ready flux language

Paste your comparative income statement, get instant dollar and percent variances, then AI-drafted results-of-operations explanations that follow Item 303 conventions: quantified, attributed only to drivers you state, with clearly marked placeholders where the cause is unknown. It never invents a reason.

Up to 30 rows · math in your browser · AI drafts follow Item 303 results-of-operations conventions · no drivers invented

Step 1. Enter your two periods

Type into the table, or copy the three columns (line item, current period, prior period) straight from Excel and paste into any cell. Amounts accept $ signs, commas, and parentheses for negatives.

Labels appear in the drafts, e.g., "increased $2.5 million, or 136%, in Q2 2026 compared to Q2 2025."

Line item Current ($) Prior ($) $ change % change

Formulas, computed live in your browser: $ change = current minus prior. % change = $ change divided by the absolute value of prior (shown as n.m. when prior is zero).

Context notes (optional, up to 500 characters. This is the only place the AI learns causes from)

0/500

Step 2. Draft the explanations

Sends the completed rows (up to 5 on the free tier) plus your context notes to the drafting service. Where your notes explain a change, the draft attributes it. Where they do not, the draft marks the gap with a placeholder for you to fill in.

How this works, and what it will not do

The drafts follow the conventions of Item 303 of Regulation S-K for results of operations:

What it will not do: it will not invent drivers. If you do not tell it why revenue rose, it writes [DRIVER: describe the volume, price, or mix driver] instead of guessing. It also will not assess materiality for you, evaluate known trends and uncertainties, or replace review by management and counsel. It drafts; you decide.

Frequently asked questions

What does the MD&A Flux Explainer do?

You enter or paste P&L line items for two comparative periods. The tool computes dollar and percent changes in your browser, then drafts one to two sentences of MD&A results-of-operations language per line, following Item 303 conventions: quantify, attribute, disaggregate.

Does the AI know why my numbers changed?

No, and it will not pretend to. It attributes changes only to causes you state in the context notes. Where the cause is unknown, it inserts a marked placeholder for you to complete. It never invents a driver.

Is my financial data stored?

The variance math runs entirely in your browser. When you request AI drafts, only the submitted rows and context notes are sent to the drafting service; the site does not log or store the request payload.

What are the free tier limits?

Up to 5 line items per AI run and 3 AI runs per browser. The variance table itself is free and unlimited up to 30 rows. Full access will be part of Unfolding Filings, coming soon.

Can I file the AI-drafted language as-is?

No. AI-drafted language requires review by management and counsel before use in any filing. This tool provides general drafting assistance, not accounting or legal advice.
