About SherlockAI

SherlockAI is a free browser-based deduction game inspired by the classic twenty questions format. You think of a famous character, a real-world career, or answer questions about yourself, and the game asks structured clue questions until it can make a deduction. Everything runs as an interactive web app: there is nothing to install and no account to create.

What You Can Play

• Characters: a catalog of 600 famous names spanning real people, superheroes and comics, anime and manga, video games, movies and TV, and literature and mythology. The full list is published on the character catalog page.
• Careers: 152 professions guessed through clues about duties, tools, training, and work environments, listed on the career catalog page.
• Sherlock's Profile: a case-file style personality profile generated from your own answers instead of a hidden target.

How The Game Works

Each mode is powered by a local deduction engine. The engine stores a probability for every candidate in the catalog, re-weights those probabilities after each of your answers, and then selects the question with the highest expected information gain. That is why the game can narrow hundreds of candidates down to a single guess in a relatively small number of questions. The engine runs in your browser, so normal gameplay does not depend on live chatbot responses or a network connection.

Original Site Content

SherlockAI is built on authored data rather than scraped or generated filler. Every character and career is hand-tagged against a shared trait set, every clue question is written and reviewed before it ships, and the site also publishes original guides such as the how to play walkthrough, the deduction strategy guide, and the FAQ. The site exists first as a game and a reference for its players, not as an article directory.

Technology

The interface is built with React and Vite and is hosted on Cloudflare Pages. The playable catalog ships as structured JSON, the deduction engine is written in TypeScript, and the progressive web app can cache core assets for faster repeat visits.
