Movie Tagline Generator

The Movie Tagline Generator turns a short description of your film into one, three or five taglines written by an AI model. Type up to 300 characters about the plot, genre and mood, pick a tone from a list of 22 (or type your own), choose one of 25 languages, and press the button. The taglines appear as a list with copy, download and share buttons underneath. It's for indie filmmakers putting together a poster, students with a short-film assignment, and writers who want a hook line for a pitch deck or a fictional movie inside a novel.

The settings, and what they change

• Description (required, 300 characters). This is the input the model works from. Genre, protagonist, the central conflict and the ending you're willing to hint at all improve the results. "A horror film about a lighthouse keeper who hears his dead wife on the radio" gives sharper lines than "a scary movie".
• Number of taglines. 1, 3 or 5. Three is the default and usually the right amount for comparing angles.
• Tone. Professional is the default; the other options include Humorous, Bold, Nostalgic, Provocative, Minimalistic, Whimsical, Serious and more. Choosing Other reveals a text box where you can type any tone, such as "deadpan" or "1980s trailer voice".
• Language. English by default, with Spanish, French, German, Japanese, Hindi, Korean, Arabic and 17 others in the list. Other lets you type a language that isn't listed.

Under the results, the copy button puts all taglines on your clipboard, the download button saves them as a text file, and the share icons post them to WhatsApp, X or Facebook.

How to write a movie tagline (and how to judge the output)

A tagline is not a summary. It's the line under the title on the poster, and it has three jobs: set the tone, hint at the conflict, and be short enough to read from across a room. The classic ones are under ten words. "In space no one can hear you scream" (Alien) tells you the genre and the setting without naming either. "Just when you thought it was safe to go back in the water" (Jaws 2) sells the sequel on the memory of the first film. "Who ya gonna call?" (Ghostbusters) is a question the audience already knows the answer to. When you read the generated lines, keep those tests in mind: cut anything that explains the plot, keep anything that makes a promise. The generator is good at producing the sort of rhythm and contrast ("One town. One secret. No way out.") that poster taglines use, and less good at knowing what your film is actually about, so the description matters more than the tone setting.
