A transparent 0–100 screening score combining solvency, profitability, valuation and shareholder returns, with earnings quality acting as the gate.

Every investor eventually runs into the same problem: there is too much economic data and not enough time. Scroll through any financial news feed and you'll find dozens of releases competing for your attention from inflation prints, jobs reports, yield moves to sentiment surveys, each presented as if it's the one number that matters. It isn't. No single indicator tells the full story of where the economy stands, and chasing headlines one release at a time is a good way to end

Ask ChatGPT to analyze a stock and it will, without hesitation, give you an answer, a valuation, a summary of the balance sheet, a view on whether a company looks cheap or expensive. It reads confidently, it's well-written, and it's available instantly. For a growing number of investors, that's become the first stop before making a decision. The problem isn't that ChatGPT can't talk about stocks. It's that the confidence of the answer and the reliability of the answer are two

A falling price is not the same thing as a cheap stock. A stock that has dropped 30% can still be overvalued, that's often exactly what's happening when the drop is the market catching up to a valuation that was already stretched, or reacting to a genuine structural change in the business, like a fading moat, a shrinking market, or a broken growth story.

By the time they get around to asking "can I actually trust these numbers?", they've already fallen in love with the idea of owning the stock.

VingeGPT started from a simple idea and a strong conviction: despite the abundance of financial tools and websites, most investors are still poorly supported in their actual investment journey. Existing solutions are often either too complex, too narrow in scope, or overly focused on raw data without helping investors interpret it nor giving the possibility to interact in natural language with an AI companion. For serious, long-term investors, information alone is not the pro
