AnalystBook vs Koyfin
Market analytics.
Or filing-grounded research.
Koyfin is a market-analytics platform — charts, screeners, dashboards, and macro data, a popular Bloomberg alternative. AnalystBook is filing-grounded research: a grounded Intelligence Brief, sector-calibrated forensic scores, filing-extracted numbers, and Ana. Here's an honest look at where each one wins.

The difference
AI Intelligence you can verify.
AnalystBook's Intelligence Brief reads the official filing and writes the analysis in plain language, grounded in the source. The numbers are computed, not generated, so the same filing always returns the same answer. And you can ask Ana, our in-app AI research analyst, anything about a company: she answers from AnalystBook's own structured, industry-aware data — the filings we organize for every U.S. public company — citing her sources and declining whatever she can't ground. Because we structure and own that data, she reasons over clean, comparable facts, not loose document text. Like any AI it can still make mistakes — which is exactly why her answers cite their sources for you to verify. Intelligence you can verify, not a chatbot you second-guess.

FAQ
Common questions.
Is AnalystBook a Koyfin alternative?
They solve different jobs, and many investors use both. Koyfin is a market-analytics cockpit — charts, screeners, dashboards, macro data. AnalystBook is filing-grounded research — a grounded Intelligence Brief, sector-calibrated forensic scores, filing-extracted financials, and Ana. If you want grounded AI reading of the filings, choose AnalystBook; if you want charting and screening, Koyfin.
What is Ana, AnalystBook's AI research analyst?
Ana is AnalystBook's in-app AI research analyst. Ask her anything about a company and she answers only from AnalystBook's own structured data — the official filings we organize and index, industry-aware, for every U.S. public company — citing her sources. She doesn't use the open web or outside knowledge and gives no buy, sell, or hold verdicts, and she's designed to decline whatever she can't ground. Because we own and structure that data, Ana reasons over clean, comparable facts, not loose document text. Like any AI she isn't infallible, so her answers cite their sources for you to verify. For research only; not investment advice.
Does AnalystBook have charts and screeners like Koyfin?
No. AnalystBook is a research tool focused on the filings — a grounded AI brief, sector-calibrated forensic scores, and filing-extracted financials — not a charting or screening terminal. It's designed to help you read a company deeply, not scan the market visually.
Is AnalystBook just for reading filings, or does it organize my research too?
Both. Beyond the dossier and the Intelligence Brief, AnalystBook is a research workspace: follow the companies you cover, keep notes pinned to the filing, track open theses and to-dos, and get quarterly review reminders. Your work persists per company, so you pick up where you left off months later.
