What this will cost, and what everyone else charges

“Free during beta” tells you nothing about what happens next, and a pricing page that leaves that blank is asking you to adopt something on the assumption it stays cheap. So here is the market, with real published figures, and the band Day91 will land in.

 What they chargeWhat you get for it
AlphaSense Roughly $24,000–$60,000 a seat, a year. 500M+ documents, broker research, expert-call transcripts, Office add-ins. Genuinely the deepest corpus in the category.
Hebbia Enterprise, quoted. Sold to firms measured in trillions of AUM. A document matrix built for diligence at deal scale, with the security posture that implies.
Klue / Crayon Commonly $15,000–$40,000 a year. Battlecards, win/loss, enablement workflow. The category standard for a product marketing team.
IndustryLens €59 a month, published. 350+ monitored sources, a Monday brief in Slack, confidence scoring on every insight.
Parano €89–€299 a month, published. Autopilot competitor monitoring across marketing, product, pricing, reviews, hires and funding.
Day91, after beta The watchlist will land between $100 and $400 a month. Everything else stays free. Eight companies read weekly by a person. The band narrows to a single number before anyone is charged.

Why the watchlist is the only thing that gets priced

The Check, the Grid, the Mirror, the Diff, the Reversal and the Battlecard run entirely in your browser against a static file shipped with the site. They cost nothing to serve, so charging for them would be charging for access rather than for work. The Wire reads SEC’s public feed. The MCP endpoint reads the same JSON this site reads.

The watchlist is different: a person reads eight companies’ filings every week. That is the only thing here with a recurring human cost, and it is the only thing with a recurring price. It is also why it caps out around twenty to thirty companies in total — the constraint is a working day, not a server.

Founding seats are exempt from whatever that number turns out to be — permanently.

FAQ

Questions

How does this compare to Klue, Crayon or AlphaSense?

They solve different problems and mostly cost between $15,000 and $60,000 a year. There is a full breakdown on the comparison page. Short version: they read websites or sell to investors; this reads filings against themselves and grades its own sourcing. As of v3 the filings checks are arithmetic on structured XBRL rather than prose analysis, so a restatement it reports is the company's own number revised, with both submissions linked.

Why is everything free?

Because the tools are new and the only way to find out what they get wrong is to have people use them and tell us. Charging for that would be charging you to test something. When the corrections log is long enough to be evidence rather than a promise, pricing starts — and the tools that get priced will be the ones doing continuous work, not the ones you run once.

What will eventually cost money?

The continuous ones: the watchlist, scheduled pricing monitoring, and category coverage. Running something on a schedule costs real money every week. Running a tool once in your own browser costs nothing, which is why the Check, Benchmarks, the Mirror and the Reversal are likely to stay open — the facts they read are a static file shipped with the site, not a metered API call. Saving results as a PDF may move behind a seat.

Why is the future price a range and not a number?

Because a range is what's known today. Every other figure on this site links to a document, and the price will too once it has been tested with real users. It narrows to a single figure before anyone is charged, and founding seats are exempt either way.

Is there a trial, a card, or a call?

None of the three. Nothing on this site asks for a card, and beta has no timer on it. Founding seats take one email. There are no demos, onboarding calls, retainers or advisory tiers — everything sold here is something the pipeline produces and a human approves.

Can a vendor pay to be covered?

No. Coverage of a category is never sold to a vendor competing in it — not as sponsorship, not as a briefing, not as a partner edition. The corrections log only means something if nobody in the coverage paid to be there.

What happens to my data?

Every tool runs in your browser. There is no backend, no account and no analytics cookie. The Diff keeps its baselines in your own browser storage so it can compare week to week without a server; clear it any time. The one exception is fetching a URL, which a browser cannot do directly — the address is passed to a public read-only extractor. Only the URL travels.

How many companies does this actually cover?

Two numbers, because one would be misleading. 104 companies resolve to a verified CIK, which means the routes go to the right company's filings rather than to a name search that can land on the wrong entity. 17 currently carry the structured fact series that the restatement, dropped-disclosure and divergence checks run on. Every page that depends on that dataset prints both figures at the top, including the fact that it is still a seed. Coverage grows by running the ingestion script against more tickers, not by publishing more issues.

Which companies can I track?

Any US filer. Covered companies return a written dossier built from filings someone opened; everything else returns live routes into that company's own filings on EDGAR, plus a place in the coverage queue.

How do I cancel?

Unsubscribe from any email. Nothing to cancel, since nothing is charged.

Tell us what it got wrong.

There is nothing to buy yet, so there is no demo to book. What is useful right now is the company we haven’t covered, the cell that came back empty, or the number we read wrong.
