Email-delivered fanfiction where you steer every chapter
Each chapter is written specifically for your request rather than pulled from a shared library, with the relationship dynamic you choose.
You receive chapters by email and reply directly to influence the story, so no separate app or login flow is needed to keep reading.
Steer the plot either with predefined buttons for quick choices or with free text when you want to describe something specific.
Both the first chapter and each requested continuation are delivered within a 24-hour window.
Paraphrase, proofread and summarize text with an AI writing workspace
Rewrite sentences and paragraphs in modes like Standard, Fluency, Formal, Simple, Creative and Shorten/Expand to match tone and length.
Scan your text for grammar, spelling, punctuation and clarity issues and apply suggested fixes.
Condense long documents or articles into key points, with adjustable length.
Generate citations in APA, MLA, Chicago and other styles from a URL, title or DOI.
