Browser-based deduction game

SherlockAI

SherlockAI is a free deduction game that runs entirely in your browser. Think of a famous character, a real-world career, or answer questions about yourself, and the game asks a series of structured clue questions. After each answer it updates its internal probabilities and asks the most informative question next, until it is confident enough to make a deduction.

How a round works

Every round follows the same simple pattern. You pick one secret answer in your mind, then respond to each clue with one of five choices: Yes, Probably, I don't know, Probably not, or No. The engine treats every answer as evidence, eliminates candidates that no longer fit, and keeps asking until it can name your character or career. If the first guess is wrong you can reject it and the game continues with the remaining candidates.

Three game modes

Characters challenges the game to deduce one of 600 famous names across six categories: real people, superheroes and comics, anime and manga, video games, movies and TV, and literature and mythology. Careers works the same way with 152 professions, using clues about daily duties, tools, training, and work environments. Sherlock's Profile turns the questioning around and builds a case-file style personality profile from your own answers.

An authored catalog you can browse

Unlike games that improvise their questions, SherlockAI runs on a hand-curated catalog. Every character and career is tagged against a shared set of traits, and every clue question is written and reviewed before it ships. You can browse the full character catalog and career catalog before you play, and you can suggest missing names at the end of a round.

Learn to play better

New players can read the how to play guide for the basic rules and answer choices, or dive into the strategy guide to learn how information gain works, how to answer borderline clues, and how to pick targets the engine can find quickly. Common questions are answered on the FAQ page.

Private and lightweight

The main game runs client-side with local probability logic. No account is required, nothing you answer is sent to a chatbot, and your preferences and game statistics are stored on your own device using browser storage. You can clear them at any time from your browser settings.
