Use ChatGPT if…
You want a general-purpose assistant for everything, and you're comfortable pasting documents in and independently verifying any number or quote it produces.
AnalystBook vs ChatGPT
ChatGPT can summarize a filing you paste in, but it has no live filing data, no source links, and can hallucinate numbers. AnalystBook is built for the job: grounded AI over stored official filings, deterministic numbers, forensic scores, and Ana — every claim checkable. Here's an honest look at where each one wins.

The difference
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.

Which one is right for you
You want a general-purpose assistant for everything, and you're comfortable pasting documents in and independently verifying any number or quote it produces.
You research public companies and need answers grounded in the actual filing — deterministic numbers, source links to the paragraph, forensic scores, and Ana, an AI built not to answer beyond the source.
FAQ
It can summarize a filing you paste in, but it has no live access to filings, doesn't link claims to a source, and can hallucinate figures — so you have to verify everything. AnalystBook is purpose-built: it already holds the filings, computes the numbers deterministically, links every claim to the paragraph, and Ana declines what she can't ground.
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.
AnalystBook's numbers are deterministic — computed from the filing, not generated — the written analysis is bound to the source, and Ana answers only from stored official filings with citations and no outside knowledge. ChatGPT is general-purpose and can produce confident but unsourced or incorrect answers about a company.
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.
