Read the quarter, not the headline.

We pull the company's own filing first, then write the brief. Any US-listed company, in about a minute.

Underline builds one brief per company per quarter, grounded in that quarter's SEC filing. Where a figure isn't in the filing it says so rather than inventing one.

What a brief contains

Signal, financials, segments, risks, management, news and a scorecard — on every plan. The Setup (three scenarios for next quarter and what would confirm each) and six quarters of Hindsight are Pro. Reach back to 2009, limited by how far XBRL data goes in EDGAR rather than by your plan.

Plans

Free — $0

Five briefs a quarter, the Top Five briefed for you, a watchlist of ten, this week's earnings calendar, your last twenty briefs kept.

Pro — $40 a quarter, or $140 a year

150 briefs a quarter, The Setup, six quarters of Hindsight, PDF export, an unlimited watchlist, a brief waiting the morning after anything you follow reports, and nine weeks of calendar. Earnings arrive quarterly, so the plan does too — nothing renews monthly. Cancel any time through Stripe's own portal.

IPO filings

A company going public files an S-1. Underline reads the filing's own tables and footnotes and sets them side by side: how much of a headline loss is an accounting mark, what the offer values the company at, and what changed between amendments. Every figure is the filer's; none is written by a model.

Coverage

Any company that files with the SEC, including foreign companies that list here. A company traded only in London or Tokyo doesn't file, so we can't cover it. A brief that fails to build is never counted against your allowance.

A brief describes what a company reported and grades the quarter. It is not investment advice, and the grade is a read on the quarter rather than a price target.
