Portal Interactive crafts interactive experiences for mobile. Our first is Story Orbit — a place where every choice opens a parallel universe, and no story is ever forced into a single ending.
Every story is just one of infinite universes — Story Orbit is where you explore the rest. Swipe once and a story begins. Branch any moment and a parallel universe unfolds. Not a writing tool, but a portal into every version of the tale.
This is the gravity at the center of Story Orbit. Long-press any paragraph, ask "what if?", and a parallel universe spins into being. Every branch keeps orbiting — switch between them whenever you like. There's no wrong turn here, only another world to explore.
Open the app and swipe. Worlds and tropes collide — cyberpunk × enemies-to-lovers × amnesia — until one spark pulls a whole universe into orbit.
Your story surfaces like ink blooming across paper, blur to clarity — the universe in your head, made visible.
Long-press any line to split the timeline. Every "what if" becomes its own universe, and you can jump between them at will.
An AI reader travels each universe with you and reacts — less a critic, more a fan already waiting on your next chapter.
Swipe-to-discover prompt cards. Five cards in, a universe assembles itself — no blank page, ever.
Each scene surfaces from blur to focus, like a world developing into view — not a typewriter, but your imagination appearing.
Long-press to branch any paragraph. "What if he never left?" — one second, one new universe.
Lost between universes? Draw three direction cards — swipe left to skip, right to take. As addictive as the story itself.
Preset knowledge graphs for popular worlds — characters, timelines, and relationships carried into any universe in one tap.
A reader's-eye reaction to every chapter — the pull that keeps you writing the next universe.
Portal Interactive, Inc. builds portals between worlds — interactive experiences for mobile, designed and engineered end to end, from first spark to the App Store. Story Orbit is the first universe we've opened. It won't be the last.
