Good to know
What DalalOS takes care of
- Splits and bonusesReturns, CAGR and the 52-week high and low use prices adjusted for splits and bonuses. EPS growth uses split-adjusted EPS.
- Recent splits are flaggedIf a split or bonus in the last year affects the 52-week range or a ratio, the answer says so.
- Growth from a lossWhen the earlier figure is a loss, growth shows as "not meaningful" instead of a misleading percentage.
- No hindsightEach past P/E uses only the results that were public on that date.
- New listingsA company's years before listing come from its IPO prospectus, and are labelled that way.
What it doesn't do yet
- Live pricesPrices update after the market closes. Live prices aren't built yet. We plan to add them.

Questions
Is DalalOS free?
Yes, to start. The free plan gives 500 credits a month and needs no card. A credit is used each time your AI calls a DalalOS tool. Test questions on this page don't use credits.
Does DalalOS tell me what to buy or sell?
No. It gives data and ratios calculated from that data. It never says what to buy, sell or hold.
What is an MCP server?
MCP is the standard way AI apps connect to outside data. Think of DalalOS as a socket and your AI app as the plug. Connect once, and your AI uses DalalOS whenever a question needs market data.
Is DalalOS a chatbot?
No. It's a plug-in (an MCP) for your AI. The box on this page lets you try it first.
How do I connect DalalOS to ChatGPT?
Open DalalOS in ChatGPT's plugin directory, click Install, then sign in to DalalOS. Start a new chat and ask about an Indian stock. It's listed for accounts in India. Outside India, use the manual setup.
Can ChatGPT screen Indian stocks?
On its own, ChatGPT searches the web for articles. It can't screen every NSE and BSE company against your conditions, and it doesn't have years of daily prices and quarterly results to work through. DalalOS gives it both.
Who is it for?
Anyone curious about Indian markets: people who track the market themselves, developers building AI tools, fund managers (PMS, AIF), research teams and students.
AI agents PMS and AIF monitoring Research desks Research Indian stocks with AI
Why do I need to sign in to ask?
Sample answers don't need an account. Your own questions do, so each person gets 5. Sign-in is free and takes one step with Google. You use the same account when you connect your AI.
What happens after my 5 test questions?
You get 5 more on the first of next month. To keep asking now, connect DalalOS to your AI. The free plan needs no card.
How is it different from ChatGPT or NSE's MCP?
On its own, ChatGPT searches the web. It can't screen the whole market or work through years of daily prices and results. NSE's MCP covers NSE prices and trading data. DalalOS adds screening, company results, shareholding, filings, IPOs and the economy, from NSE, BSE and other sources.
Do you keep my questions?
Questions typed in the box are kept for 90 days to improve answers, then deleted.
How fresh is the data?
Most figures update after each trading day. Every answer shows the date of its data.
What if a company isn't covered?
DalalOS covers companies listed on NSE and BSE. If one you need is missing, tell us and we'll look at adding it.
Is DalalOS SEBI-registered?
No. DalalOS is not a SEBI-registered investment adviser. It publishes market data and ratios calculated from that data, and gives no personal advice or recommendations.
