The Stock Filter — a one-person intelligence platform covering 5,765 Indian companies, 15,700+ earnings calls, and nearly half a million signals — is live, free, and unlike anything Indian retail investors have had access to before.
Every year, lakhs of Indians open their first demat account. They download a trading app, buy a stock someone mentioned in a YouTube video, and wait. Some get lucky. Most learn an expensive lesson. The tragedy is not that they lost money — it is that nobody gave them the tools to know better.
The brokerage gave them a button to buy. The screener gave them a table of numbers. The Telegram channel gave them a tip. But nobody gave them what a professional fund manager takes for granted — structured intelligence. The ability to look at a company and understand not just what the numbers say, but what they mean. Where they come from. And whether they can be trusted.
Vicky Roy spent 12 years watching this gap widen — working across finance, technology, and data in roles that forced him to sit at the intersection of how markets generate information and how technology can make sense of it. The conclusion he arrived at sounds simple but carries weight: Indian retail investors are not information-starved. They are intelligence-starved. The raw data exists everywhere. What does not exist is a system that connects the dots, shows the evidence, and trusts the investor to think.
So he built one. Alone.
The Stock Filter (thestockfilter.com) is now live — covering 5,765 publicly listed Indian companies. The platform has processed over 15,700 earnings calls, tracks more than 491,000 signals drawn from nearly 248,000 source documents and 280,000+ corporate announcements. Every company page is a living dossier — financial statements, valuation history, shareholding trends, mutual fund activity, management commentary, and AI-generated intelligence from earnings calls.
The tagline says it plainly: Intelligence with receipts.
Every company receives a TSF Score — a composite rating visualised as a five-dimension radar showing Business quality, Captain (management), Opportunity, Environment, and Secular positioning, each scored out of 100. Below that sits the X-Ray Checklist, an auto-generated set of pros and cons that gives investors an instant read on what is working and what warrants caution. And for those who want to dig deeper, there is Ask AI — a conversational assistant on every company page that answers questions in context, with streaming responses drawing on the platform’s entire intelligence base for that company.
Perhaps the most distinctive module is Shenanigan Detection — an automated accounting red-flag scanner that grades companies as Clean, Medium, or High severity. The system also runs a Reverse DCF calculator on every company page, answering the question every value investor asks: what growth rate is the market already pricing in?
“I did not want to build another screener,” says Vicky Roy, founder of The Stock Filter. “Screeners give you numbers. Tip sheets give you conclusions. I wanted to build something in between — a system that does the analytical heavy-lifting but never hides its reasoning. The investor should always be able to ask ‘why?’ and get an answer with a source attached.”
The platform’s architecture reflects that philosophy at every level. India’s equity universe is mapped into 14 sectors and 40 sub-sectors through The Canopy — a proprietary taxonomy built from how companies actually generate revenue, not the legacy index classifications that lump disparate businesses together. Forty thematic Secular Currents — including Premiumisation and Chemical China+1 — cut across sectors to surface connections that traditional analysis misses. A company building EV charging stations and a company manufacturing copper wiring may sit in different sub-sectors, but they ride the same structural wave.
The Lens offers a daily-updated ranking of the most noteworthy movements across the universe. The Filing Room makes 280,000+ corporate announcements searchable. And the Markets Dashboard — with modules named The Pulse, The Rally, The Slide, The Tide, The Shadow, and The Blotter — gives investors a real-time read on breadth, flows, and institutional activity.
For investors managing actual portfolios, the platform runs Portfolio Health Diagnostics — assigning a health grade, analysing correlation and sector concentration, and flagging holdings where shenanigan alerts have been triggered.
And here is what may be most striking: all of it is currently free.
The Stock Filter is open to every registered user — full access to company intelligence, earnings call analysis, transcripts, and the complete analytical suite. No trial period. No paywall on core insights. Premium tiers are on the roadmap, but the present stance is deliberate: prove the value first, earn the right to charge later.
“In an industry that routinely charges for mediocre data behind aggressive paywalls, I wanted to do the opposite,” says Roy. “Let people use it. Let them verify every claim I make. If the intelligence is real, the business model will follow.”
What makes this story uncommon in India’s startup landscape is not just the ambition — it is the execution without the scaffolding. No engineering team. No venture capital. No growth hacks. One person who decided that 5,765 companies deserved to be understood, not just listed — and then built the system to do it.
The platform is live. The data is current. The coverage is not a roadmap slide — it is a fact anyone can verify in sixty seconds by visiting any company page on thestockfilter.com.
Indian retail investors have waited a long time for a platform that respects their intelligence as much as it respects their capital. That platform is here.
