The tools

Eight instruments. One desk.

Four read your own numbers. Four read theirs. Every line comes back with the filing or pricing page it was taken from.

Open during beta — no account, nothing gated
Data

What these tools are actually reading

Two of the eight run entirely on numbers you type and need no dataset at all. The rest depend on the structured fact layer below, and it is published rather than implied — including when it is thin. A tool with no data for a company reports that it has no data, never an empty result dressed as a clean one.

Try before you click

Pick a tool. See what it hands back.

Point it at yourself

Two tools that grade your own reporting before someone else does.

Point it at them

Three tools that read the other side’s own documents back to you.

Take it into the room

One turns findings into something an AE can carry. The other tells you when the next filing lands.

Point it at the calendar

The one tool that runs the other seven for you, on a schedule.

Different jobs

They run in an order.

A grid cell marked unread is a Reversal waiting to be run. A material price change in the Diff is a question for the Check about whether your own price holds. The handoff is the product — the tools are just where it happens.

All eight also run from inside Claude or Cursor. The MCP endpoint exposes the same filing-sourced data as five read-only tools, so the question you had while drafting a deal review gets answered where you had it.

Who

Nobody needs all eight.

Each role lives in two of them.

RevOps / Pricing

The Diff → The Check

See what comparable vendors repriced this week, then test whether your own retention and ARPU still agree before committee.

Founder / CEO

The Check → The Mirror

Find the two board-deck metrics that contradict each other, then whether your positioning says anything theirs doesn’t.

Product marketing

The Mirror → The Diff

Locate the dead phrases your category shares, then watch which competitor moves price or packaging behind them.

Corp dev / Investor

The Grid → The Reversal

Build the comp set in one view, then take the odd-looking names and find where their filings disagree across periods.

Resources

Two tables the tools draw on.

Privacy

What leaves the page.

No backend, no account, no analytics cookie. Your figures, competitor list and pasted text are processed in this browser; the Diff keeps its baselines in your browser’s own storage, clearable any time with Forget all.

One exception: fetching a live page needs a helper, so the address goes to a public read-only text extractor. Only the URL travels — paste anything unpublished instead.

Weekly
Scope

Scope

Where the tools work best.

The bench is built around primary documents. Knowing its edges up front makes the eight tools easier to point at the right question.

US filers EDGAR is the corpus, so US public companies are read end to end. For private or overseas competitors, the Mirror and the Diff work off their public pages.
Weekly rhythm Everything runs on demand in the browser, plus one email a week. Push alerting is on the roadmap.
Primary documents only Filings and published pricing pages. Win/loss, intent and hiring proxies are useful, and they live in other tools.
Depth over breadth A human approves every figure, which keeps coverage around twenty to thirty companies — and keeps the output quotable.
Evidence, then judgement The tools say what a document contains and what to ask about it. The call on your deal stays yours.
