FAQ

Common questions.

How does the trial work?

14 days free. Card required at signup so we can switch you to the paid plan without an interruption. Cancel any time during the trial and you won't be charged. Your notes and companies are kept if you come back.

Where does the data come from?

SEC EDGAR. Every number on the page links back to the filing it came from — click through to verify anything in one step. No third-party data vendors, no paid feeds.

Who is AnalystBook for — and not for?

Built for analysts and investors who build conviction one company at a time: sell-side juniors, long-only PMs, family-office researchers, credit analysts, activist associates, journalists covering specific companies. Not built for day traders, quant funds, macro traders, or news-feed skimmers — those are adjacent products we deliberately don't try to be.

Can I cancel anytime?

Yes. Monthly billing, cancel from settings. Your data stays put if you come back. We don't delete notes or watchlists on downgrade.
