Penveil

Turn your idea into a chapter-by-chapter plan, write with an AI co-writer that matches your voice, and export a beautifully typeset book.

Penveil is the writing system for finishing books — not just starting them.

Tell Penveil what you're writing and it turns your idea into a usable chapter-by-chapter blueprint: premise, characters, locations, and a clear job for every chapter. Then write in focused chapters with tools that keep you moving and keep your story consistent.

WRITE WITH MOMENTUM • Co-write continues your scene in your voice — accept with a tap, or ignore it and keep typing • Guided mode asks short questions and shapes your answers into prose • Voice capture turns spoken ideas into notes and chapters • A keyboard toolbar puts bold, italic, undo, and Continue right above your keys

KEEP THE STORY CONSISTENT • Your Story Bible tracks characters, places, and details as you write • Chapter contracts give every chapter a purpose — and Penveil helps you keep it • The promise ledger remembers what you set up so nothing is left unresolved • Beta readers give you honest reactions before any human sees a word

EVERY KIND OF BOOK Novels, memoirs, autobiographies, self-help, business books, children's books, picture books, academic writing, songwriting, and screenwriting — each with tools that speak its language, from industry-format screenplay exports to lyric sheets with chords to a companion workbook for practical books.

FINISH AND SHIP • Export beautifully typeset PDF, Word, and ePub — plus Fountain for scripts • Generate query letters, synopses, and marketing copy when you're ready to pitch • Publish a public page for your book and send new chapters to followers by email
