Loved by indie developers
“I shipped my Game Jam entry with AI-generated sprites and BGM from GAMEGEN AI. Saved me at least two days of asset work.”
“The character and asset pack tools let me test combat feel before hiring an artist. The style was consistent enough for a vertical slice.”
“HD portraits with transparent backgrounds dropped straight into Ren'Py. We iterated on character designs in hours instead of weeks.”

FAQs
Frequently asked questions
The AI interactive movie game. Players write each choice into another universe, AI shoots the scene, and everyone can continue it. Each interactive movie game is a shared world with a cast of actors.
When you continue a branch, your video starts from its last frame and appears under it on the tree. Several players can continue the same branch, so one interactive movie game splits into many paths and endings.
Every interactive movie game has a cast of reference images — actors, scenes, and props — like a short-drama production. You pick who appears in your scene, and their images are sent to the video model with every branch.
Every account can choose a 3-, 5-, or 10-second branch. Each length costs credits, and generation starts only when the balance covers it. New accounts get signup credits, enough for one 3-second branch. Pro ($9.9/month, 100 credits) and credit packs add more. Failed branches are refunded automatically.
Everyone. Branches are public by default and show your display name, which you can change before posting.
Yes. Character Showcase, characters, monsters, maps, textures, and audio tools are all still in the Tools section — handy when an interactive movie game needs a new cast member or your own game needs a video.

Interactive movie games you write with other players
GameGen — Co-create the multiverse. You write the next choice, AI shoots the scene, and that branch becomes another universe anyone can continue.
Continue any branch and your video starts from its last frame, hanging under it as a new branch. Fork an interactive movie game at any point, replay any path from the opening, and see where other players took the same world.
Alongside the interactive movie games, GameGen keeps a toolbox of AI generators for game creators — character showcases, sprites, monsters, maps, and textures — for building a new cast or a game of your own.
