Hindsight

Compare stock price history, then ask AI about it

Enter up to eight tickers to load anywhere from 3 months to 10 years of daily prices, see them on one chart, and ask questions in plain English: biggest drawdowns, best days, how closely they move together, and more.

Up to 8 tickers, separated by commas or spaces. Add an exchange suffix for non-US stocks, for example VOD.L. Choose 3 months to 10 years of daily history.

Enter some tickers above and press Load history.

About Hindsight

How it works

  1. Type some tickers, choose how far back to go, and load the daily prices.
  2. Compare them on one chart and in the summary table.
  3. Ask the AI a question, or re-run one of your saved queries.

Where the data comes from

Daily prices come from Yahoo Finance, with Twelve Data as an optional fallback. Optional live US prices use Alpaca's free IEX feed. Free data sources can be delayed, limited or occasionally wrong, so check anything important.

Your keys and privacy

You bring your own API keys in Settings. They stay in your browser. When you ask a question, the loaded prices and your question are sent to the AI provider you chose, and nowhere else.
