About

What it is

Stock Rediscover takes one well-known company at a time and rebuilds it from its own filings: what it sells, where the money comes from, what the numbers say and where each valuation ratio misleads. You read a unit's cards, take its quiz, and anything you get wrong waits under Blind spots until you get it right.

Every pack is generated by an AI skill from public filings and then checked, and each card carries the date of the figures it quotes. It is educational material, never investment advice, and nothing here is a recommendation to buy or sell anything.

The site is a static page with no accounts and no server. Your progress lives in your own browser; Settings lets you export it. You can also download the skills and make packs for any company or topic you like.

How the packs are made

All bundled packs are generated with Claude Fable 5 or Fable 5.1, running the company deep-dive skill against the company's own filings. One pack costs roughly 500k to 1M tokens, depending on the effort level, before checking.

The Chinese packs are translated from the English ones, so they may lag behind the English version when a pack is refreshed after a new filing.

中文学习包由英文版翻译而来，英文版随新财报更新后，中文版可能会滞后一段时间。

The site shows one language at a time; switch it in the top bar. The choice applies to the catalogue, Progress and Blind spots alike, so a translation never sits next to its original.

Who makes it

The packs started as my own way of finding out which parts of familiar companies I only thought I understood, and grew into something worth sharing.
