I've been investing for years. Index funds, some individual stocks. But I'd never read a single annual filing (10-K) for any company
I owned.
When I finally tried Apple's — 60 pages of dense financial and legal language. I gave up after 10 minutes.
So I built the tool I wished existed.
What it does
Each company gets 3 short pages:
- Overview — what the company actually does
- Income — where revenue comes from, by product and by region
- Health — key financial metrics scored against industry benchmarks
Every finance term is tappable for a plain-English definition.
The stack
- Next.js + React (frontend)
- Django + PostgreSQL (backend)
- Hosted on Vercel + Railway
What's live
10 companies: Apple, Amazon, Alphabet, Microsoft, Meta, Nvidia, Tesla, JPMorgan, Johnson & Johnson, Coca-Cola.
Free, no signup, no ads: decodingstocks.com
What I learned
- Hand-written explanations take 10x longer than I expected, but the quality difference vs AI-generated text is obvious.
- Lighthouse audits early and often — fixing performance issues late is painful.
- Legal pages (Privacy, Terms, Disclaimer, Cookies) took almost as long as actual features. GDPR is no joke even for a free tool.
Not financial advice. Would love feedback — especially what's confusing or what company you'd want added next.
