It does not replace acquisition decisions, editorial judgment, legal review, or responsibility for a manuscript. ## Product scope Manuscript projects connect manuscript text, characters, plot decisions, research, worldbuilding, and project notes. Manuscript context is plan-specific: 22,500, 60,000, or 112,500 words can be available to an AI task. Editing has three separate levels: copyediting, stylistic or line editing, and developmental analysis. Voice-preserving editing can consider sentence rhythm, syntax, word choice, and deliberate punctuation from the author’s manuscript. Publishing support includes export and publishing-related tools. Available functions and limits depend on the selected plan. ## Voice-preserving editing evidence German method article: https://epos-ai.ch/blog/stimme-des-autors-bewahren.html English method article: https://epos-ai.ch/en/blog/preserving-the-authors-voice.html German research page: https://epos-ai.ch/research/autorenstimme-ki-lektorat-2026.html English research page: https://epos-ai.ch/en/research/author-voice-ai-editing-2026.html Published internal measurements: Average measurable distance reduction: 73 percent.
