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
Can ChatGPT analyze SEC filings?
Yes — but verify everything.
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
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 from AnalystBook's own structured, industry-aware data — the source-linked filings we normalize for every public company — citing every claim 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 every claim links back to the source for you to verify. Intelligence you can verify, not a chatbot you second-guess.

FAQ
Common questions.
Can ChatGPT analyze SEC filings?
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.
What is Ana, AnalystBook's AI 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 normalize and index, industry-aware, for every public company — citing every claim. 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 every claim links back to the filing for you to verify. For research only; not investment advice.
How is AnalystBook's AI different from ChatGPT?
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.
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.
