Seph is a conversational creative collaborator for anyone building creative IP. Novelists, screenwriters, filmmakers, game designers, worldbuilders, and the next generation of creators finding their voice. Seph works alongside you, listening and thinking and taking notes, and captures your world, your characters, your voice, and your creative vision into a private AI model that belongs entirely to you. While AI can generate content faster than any human, it isn't good at originating authentic creative vision. AI produces variations. It remixes. The world, the rules, the voice; these still come from you. Seph is built on that belief. Seph engages you in conversation about your story ideas. These conversations become a living record of your world: characters, settings, scenes, plot, tone, thematic intent. Over time, Seph builds custom models of your creative IP that you can return to, expand, and work with across projects. The models are "living worlds", dynamic embodiments of your imagination. WHAT YOU CAN DO WITH SEPH - Have open-ended creative conversations about your work, by voice or text - Develop characters, worlds, plots, and tone through dialogue - Capture notes automatically as you think out loud - Train private AI models on your own creative material - Export notes to Google Sheets and other destinations - Work across sessions with full context preserved PRIVATE BY DESIGN Models trained from your work are yours. Your models are private to your account. We do not use your content to train general models, and we do not share your creative material with anyone. Third-party AI providers we work with are contractually prohibited from training on your content. EARLY ACCESS Seph is currently in early access and free to use. Paid features, including model training credits, are available for creators ready to go deeper. We're building Seph with and for creators at every stage, from established professionals to emerging voices. Your feedback shapes what comes next. ABOUT THE SUPERPOSITION The Superposition is an AI-first entertainment company building at the intersection of creative intelligence and ownership. We believe the future of entertainment will be built on author-owned AI models. Living IP that powers creatives and studios alike. Questions, feedback, or partnerships: support@thesuperposition.ai

About

Savor Reader

Savor Reader — read one sentence at a time. Most reading apps measure how much you finish. Savor Reader asks a different question: did you actually understand what you just read? Instead of scrolling a page, Savor Reader shows you a single sentence. A quiet gauge fills as you stay with it — and it won't let you move on until it does. No skim, no autopilot, no "books read" counter that means nothing. Just one sentence, fully digested, then the next. WHY SAVOR READER • One sentence per screen. The page can't overflow and your eyes can't run ahead. • A dwell gauge you have to satisfy. Rush it and nothing happens; stay with it and the sentence opens. • Five digestion stages — from Unread to Fully Digested — so every sentence has a state, not just a checkbox. • Rewind is always available. Re-reading is the point, not a failure. • A re-read queue gathers the sentences you marked as unfamiliar and brings them back at the right moment. EVERYTHING YOU NEED TO READ WELL • Import your own books: EPUB, PDF, MOBI·AZW, FB2, HTML, Markdown, and plain text. Scanned PDFs are filled in with text recognition. • Read aloud, sentence by sentence, with the spoken line gently highlighted — or turn on auto-advance for hands-free listening. • Highlight in three colors, add notes, attach a translation, or write by hand in the margin. • Find any book by title or author, or search every sentence in your library, and jump straight to the sentence you want. • Per-book statistics — time spent, sentences reached, digestion rate — and a library-wide dashboard with a reading calendar and streaks. • A home-screen widget and a Live Activity keep your last sentence within reach. • A daily sentence and a re-read list, so the writing you found hard comes back when it should. SAVOR PRO Unlock the deeper tools with a monthly or yearly subscription, or a one-time lifetime purchase: • Export your annotations as Markdown, or as an annotated PDF. Savor Reader is fully usable without Pro. YOUR READING STAYS YOURS No account. No sign-in. Your library, your notes, and your reading history stay on your device.
