10-Year Stock Value Analysis
A website and two phone apps that read 10 years of a company's SEC filings and explain them in plain English.
The website
Look up any US-listed company and get its trends, 20+ red-flag checks, its SEC filing record, insider trades and the Graham, Buffett, Lynch and Piotroski checklists. Also: compare two stocks, a saved portfolio, an S&P 500 picker, CSV downloads, English and Spanish.
Python serverless on Vercel · strict TypeScript bundled with esbuild · SEC EDGAR data
The Android and iOS apps
Native shells around the site: Kotlin on Android, SwiftUI on iOS. They add an offline screen, watch-list notifications that open the company, and saving CSV files through the phone's share sheet.
