Hi HN - I m Yashu and I ve been building Ninethirty for a while.The problem: I do my own research, and a variety of tabs open for screening, charts, financials and so on; and then a chat window where I d paste numbers for an LLM to reason and analyse them.We built NineThirty to solve a bunch of these problems -* A screener that goes deep and is genuinely customizable - fundamental, technical, news, and event criteria in the same query, not three separate tools. Besides, the problem does not end with screening - (almost) instantly backtest to understand historically what stocks have come up on the screen and their performance.* Company financials, sector views, heatmaps, events, seasonality, etc. the usual stuff* An AI assistant (Dr Market) that sits on top of this curated, processed data layer. Use it to validate a setup and it s working from the actual real time technical indicators, not a plausible-sounding reconstruction. This doesn t eliminate hallucinations. The hope is that when Dr. Market gets something wrong, it s interpreting the data badly rather than making up the data itself (or citing the wrong sources).Where it s early: coverage is US equities, and there are rough edges I know about and probably a few I don t. It analyzes; it doesn t give recommendations, and it s not advice. Free while I figure out what it costs to run and what s actually worth paying for.What I d most like from HN is to try to break Dr. Market? Ask it something where you already know the answer and tell me where it s wrong. And if the screener can t express a screen you actually want to run, that s the feedback I want most.Thanks!
