About HeyTheo: AI Stock Co-Pilot
THEO FINDS YOUR NEXT OPPORTUNITY AND PROTECTS THE ONES YOU OWN No charts. No jargon. Just a heads-up when something needs you. Most investing apps hand you a wall of data and leave you to work it out. Theo does the work — spotting the setups you would have missed, holding a protective level under what you own, and testing a strategy against real history before you rely on it. PROTECTION THAT MOVES WITH YOU The hard part of owning a stock is knowing when to let go. Theo tracks a protective level under every stock you own and raises it as the stock climbs. When it moves, Theo tells you. THE ENTRY YOU WOULD HAVE MISSED Add a stock you are watching and Theo watches the setup for you. When it reaches the level, you get a heads-up — and Theo protects it from there. Every idea is a plan, not a tip. IDEAS WITH THE OTHER SIDE INCLUDED Every idea shows the bull case, the bear case and the risk. It shows why you are seeing it, too — adjacency to something you already hold, a gap in your mix, a sector rotation. Ideas you dismiss go away. Ideas that closed stay visible with what actually happened, including the ones that did not work. BUILD A STRATEGY AND RUN IT Pick the rules. Pick the basket — the Dow 30, the Nasdaq 100, a sector, or a list of your own. Test it against years of history first, so you are judging a method instead of taking a faith claim. Then run it, and Theo keeps working it for you and tells you what it finds. THEO'S READ, NOT A DATA DUMP Tap any stock and Theo's interpretation comes first: whether the trend is constructive, strong but late, washed out or rolling over, and what that means for your position specifically. The raw numbers sit below it, one dimension at a time, for the days you want to check the work. ASK THEO ANYTHING "Why is NVDA moving today?" "What does this setup actually mean?" "Is my protective level still sensible?" Ask in your own words. Theo explains and shows its reasoning. YOUR WATCHLIST, TWO WAYS Stocks you own, where Theo watches the downside. Stocks you are watching, where Theo watches for an entry. One tap moves a stock between them. THE MARKET, ANSWERED Where money is moving by sector. The Fear and Greed gauge. Major indices. And underneath all of it, what any of it means for the stocks you hold. A CO-PILOT, NOT A TERMINAL Theo is not another screen full of charts for you to interpret. It watches the market the way you would if you had the time, and it tells you the one thing that matters right now. Go deeper whenever you want — the raw numbers are one tap down, every time. WHO IT IS FOR — Anyone holding stocks who simply doesn't have time to watch the ticker all day. — Active traders looking to capture ideal market entries consistently. — Analytical minds who demand transparent reasoning, not black-box predictions. WHAT THEO WILL NEVER DO Never tells you what to buy or sell. Never hides its reasoning behind a black box. Never passes off analyst ratings as its own recommendations. HOW HEYTHEO FITS HeyTheo acts as your intelligent analysis layer. It powers your decision-making, while execution remains entirely with your preferred brokerage account. Start free. Ask Theo your first question. DISCLAIMER HeyTheo provides independent analysis and insights for informational purposes. The app does not offer personalized financial advice or operate as a brokerage.
