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 AI Intelligence brief, sector-calibrated forensic scores, source-linked 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 every claim links to the paragraph it came from. And you can ask Ana, our in-app AI research analyst, anything about a company — she answers strictly from the filings, cites every claim, and is designed to decline whatever she can't ground. Like any AI it can still make mistakes — which is exactly why every claim links back to the source 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 AI Intelligence brief, sector-calibrated forensic scores, source-linked 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 analyst?
Ana is AnalystBook's in-app AI research analyst. You can ask her questions about a company and she answers strictly from our stored official filings and structured data, citing every claim. She's designed to decline anything she can't ground in the source — no outside world knowledge, no web search, and no buy, sell, or hold verdicts. Like any AI she isn't infallible, so every claim links back to the filing 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 source-linked 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 AI 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.
