You know that feeling when you're up at 2 AM, staring at a chart, convinced you've found a bull flag — then you wake up liquidated? Yeah. That was me. Multiple times. The problem wasn't that I didn't know technical analysis. I'd spent hundreds of hours learning patterns, watching videos, reading books. The problem was confirmation bias. When you're already in a position, your brain sees what it wants to see. So I built Trinith. Upload any chart screenshot, get AI-powered pattern detection in seconds. It tells you what it sees and how confident it is — no emotions, no bias, just pattern recognition.
Why I'm sharing this on HN:
I'm not a CS grad. I taught myself to code specifically to build this. Most of what I know came from docs, Stack Overflow, and honestly — Claude and GPT helping me debug at 3 AM. I figure if there's anywhere that appreciates "I had a problem, so I built something" energy, it's here.
Why Gemini instead of GPT-4 Vision or Claude?
I tested all three. For chart analysis specifically, Gemini gave me the most consistent structured outputs. GPT-4V was good but more expensive. Claude was sometimes too cautious, would refuse to give confidence scores because "markets are unpredictable" (fair, but not helpful for my use case).
The hard parts weren't AI — they were auth flows, credit systems, and making it not look like an MVP (I'm a backend guy, CSS hurts).
The Honest Truth Is this going to make you rich? No.
Is the AI always right? Definitely not.
What it does is give you a second opinion that isn't emotionally attached to your position. When I'm long on something, I see bullish patterns everywhere. The AI doesn't care what I'm holding. I've been using it myself for a few weeks. It's caught a few patterns I would've missed, and more importantly, it's talked me out of a few bad trades.
- People who trade and can tell me if the analysis output is useful
- People who've built with vision APIs and have optimization tips
- People who think this is dumb and can tell me whyHappy to answer any technical questions.

This should have been a "Show HN" with your large comment as the text and no URL. Otherwise you may find this gets flagged.
