Features
Trailer structure
A hook in the first seconds, a story that turns, a build that speeds up and a last shot after the title, the shape audiences expect.
Title cards that fit
Release date, tagline and credits set in type that matches the genre, timed between the shots instead of laid over them.
Cut to the music
Cuts land on the beat, the score drops out before the reveal and the hits line up with the biggest shots.
Your footage or generated
Cut a trailer from the film you shot, or generate the shots for a book, a game or a film that is still a script.
Genre on purpose
Horror holds on silence, comedy cuts on the joke, action rises in pace. The edit follows the genre you name.
Teaser, trailer and spot
A 15-second teaser, a full trailer and vertical cutdowns from one edit, each ending on the title.
Who it’s for
Authors and publishers
A book trailer for launch week that shows the world of the story, without a film crew or a stock footage bill.
Independent filmmakers
A trailer for the festival submission or the crowdfunding page, cut from your footage or made before the shoot.
Game studios and events
A reveal trailer for a game, a launch or a conference, with the date on the last card and a vertical cut for social.

Frequently asked questions
What is an AI trailer generator?
A tool that turns a story, a brief or your footage into a trailer: it writes the beats, generates or selects the shots, adds title cards and cuts it all to music.
Can I make a trailer from my own footage?
Yes. Upload the film or the clips and Chatly picks the moments, orders them into trailer beats and cuts them to the track.
Can I make a book trailer?
Yes. Paste the blurb or a chapter and Chatly generates shots of the setting and the mood, with your tagline and release date on the cards.
What music does it use?
Use a track you own or have licensed, or a generated score timed to the edit. Chatly does not supply commercial songs.
How long can a trailer be?
From a 15-second teaser to a full trailer of two minutes or more, assembled from short generated shots on the timeline.
