What it does

Most book writing tools give you a place to type. Penveil gives you a structure before you type. Answer 3 questions, get a complete blueprint: full chapter outline, purpose and conflict per chapter, characters, key locations. Under 2 minutes. Every chapter has a defined job before you open it.

Penveil is a structured writing system for finishing books. Build your blueprint, define every chapter, and write with your whole story in context. 14-day free trial, no credit card required.

Tell Penveil your idea — even a rough one — and get a complete blueprint for your book before you write a word. 14-day free trial, no credit card required. Penveil is a structured writing system for finishing books. Three layers of structure work together to keep your story consistent and your writing moving forward. When your draft is ready, Penveil typesets it into a real book — a print-ready PDF in 6×9 or 5×8 trim, or an EPUB for e-readers. Word (.docx) export is included too. Every book can open a public reader page where readers sample chapters and follow along by email — you publish chapters to your followers as you write them. Before you share, run chapters past AI beta readers for…from penveil.app

  • With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
