πŸ‘οΈ The Science of Deduction

πŸ•΅οΈ A Sherlock Holmes tool β€” The consulting detective himself

"You see, but you do not observe." Train the difference. The AI conjures a stranger described only by what the eye can see β€” the frayed cuff, the ink-stained thumb, the walk β€” at your chosen difficulty. You write your deductions; Holmes grades them claim by claim, shows you what you missed, and delivers one dry remark you'll remember longer than the score.

βœ… Free to use β€” no account, nothing to configure.

What it does

πŸ““

A field notebook

Observations arrive on ruled aged paper, exactly as a detective would jot them.

🎯

Claim-by-claim grading

Bullseye, close, or miss β€” each with the observation that proves or disproves it.

🧠

Three difficulties

From generous tells to subtle chained inference with a deliberate red herring.

How to use it

  1. 1

    Summon a stranger at your difficulty.

  2. 2

    Write everything you can deduce β€” chains score higher than guesses.

  3. 3

    Take your grade, read what you missed, summon another.

Your running average and best score are kept in this browser. Holmes remembers, even when you'd rather he didn't.
