WhatIsThisMovie is an AI-powered movie identification tool for the common situation where a film is on the tip of your tongue but the title escapes you. It is built for anyone trying to recover a movie from incomplete memories, a half-remembered scene, a quote, a mood, or an actor, rather than searching by an exact title. It runs in the browser and is free to use, with login available but not required for basic searches.
The process is three steps: describe what you remember, let the AI match it, then review ranked candidate results with enough detail to confirm the title yourself. You can search by plot fragments and scene details, by remembered dialogue, or by uploading a screenshot or poster for visual identification, and you can narrow results with filters for year, genre and country. The tool advises recalling as many specifics as possible, approximate era, genre style, actor characteristics and iconic scenes, since more detail improves the match.
Under the hood it uses large language models, specifically GPT and Gemini, matched against the TMDB movie database, with results ordered by match probability. The site reports that roughly 86% of users find their target movie among the generated results. It also states that search content is not retained or used for AI training; each query is used only to serve that one request.
A Pro plan is offered at $4.90/month (advertised at 50% off a $9.90 regular price) and adds unlimited searches, higher accuracy, faster processing and early access to new features, while a free tier provides limited searches on the basic model.
