Bob's Research vs ChatGPT for 10-K analysis
This is for investors who already paste filings into ChatGPT and want to know whether a dedicated reader is worth it. The question isn't which one is smarter. It's which one gives you the same careful read of every company, without you writing the prompt each time.
The short answer
ChatGPT is a fine tutor for what a 10-K means. Bob, the AI 10-K reader, is the better default for what this particular 10-K says: the latest filing, the same structure for every company, a 0–100 rating, and the risks, with the source a click away.
What each one does with a 10-K
ChatGPT reads whatever you give it. Upload the filing, or ask it to search, and it will summarise, answer follow-ups and explain terms. The output depends on the prompt, the model of the day and which parts of a 150-page document it chose to weigh.
Bob starts from a ticker. He pulls the latest 10-K from SEC EDGAR, layers on any newer 10-Q and material 8-Ks, and returns the same three things every time: a 0–100 rating, a short thesis and the specific risks the filing discloses.
Consistency and auditability
Ask a chatbot the same question twice and you can get two verdicts. That's fine for brainstorming and awkward for comparing companies. Bob rates every filing on the same scale with the same method, and a given filing gets one rating, the same for every reader. If you want to know why, the filing it was based on is linked.
Buried risks
Risk factors are boilerplate until they aren't. The useful ones (customer concentration, covenant terms, a going-concern paragraph, a related-party lease) tend to sit in the notes. Bob's quick read works from the high-signal sections. The forensic read on Pro goes through the entire 10-K, footnotes included, and rates the last five annual filings the same way so you can see the trend.
ChatGPT will find these if you know to ask, and if the relevant pages made it into what it read.
Charts
Bob shows RSI, MACD and support and resistance alongside the filing read. ChatGPT doesn't chart live prices on its own.
Cost
ChatGPT has a free tier and paid plans you may already have. Bob is a few free reads, then $5 a month for unlimited quick reads or $20 for the forensic read. If you already pay for ChatGPT and read one filing a quarter, you may not need Bob.
When ChatGPT is the better pick
- You want to learn what an accrual or a deferred tax asset is.
- You read a filing or two a year and enjoy steering the conversation.
- Your question is not about a US-listed company filing with the SEC.
When Bob is the better default
- You follow several companies and want them read the same way.
- You want the latest filing every time, not whatever the model remembers.
- You want a number you can compare across names and across years.
