A free stock technical-analysis app that makes momentum readable, with an AI concierge that helps you use the tool but never tells you what to buy.



Technical-analysis tools are either toy-simple or a wall of indicators only a pro can read. There was room for something in between: a clean app that surfaces one clear momentum signal and lets a regular investor compare stocks side by side.
The product and front end for a web app built around a proprietary momentum indicator and a diverging target-range gauge. Users keep watchlists, open deep per-stock views, and line several stocks up on a synced comparison canvas.
Financial software lives inside real legal lines. A concierge that gives personalized buy or sell advice would cross into regulated territory. So the ruleset came first: the assistant is scoped to help you use the tool and understand the method, and it refuses to recommend trades. Defining those guardrails precisely was as much of the product work as the charts.
This is product requirements for a technically and legally complex domain: defining a ruleset, edge cases, and a hard non-advisory boundary, then directing the front-end build against it. Defining rulesets, acceptance criteria, and failure modes is the core of the work.
Product, UX, design, and front end (React + Vite), built with Claude Code alongside a partner who owns the backend and deploy. I own how the product looks, reads, and behaves.
