A professional writing environment for novels, non-fiction, and long-form work — with an AI co-author that reads and remembers your whole book.
Draft chapters in a VSCode-style editor, keep characters and timelines in a project database, and collaborate with an AI co-author that reads your whole manuscript — so you can finish the novel, not just the first page.

Features
File tree, tabbed editor, markdown and rich-text modes — every writing session feels like your IDE.
An AI co-author reads your whole project, keeps context, and writes with you — not just for you.
Every save is chunked and embedded. The agent retrieves semantically relevant content from your entire project when responding.
One click runs a structured review: consistency, gaps, style, and chronology across all chapters and documents.
Auto-generated timeline.md, characters.md, places.md and terms.md keep your world internally consistent.
Render your project to .docx, .pdf, or .txt in seconds. Proper formatting, sorted by file path.

For authors
VoxVei is where serious writers draft, revise, and finish long-form work. You can write anything here — from literary fiction and series novels to memoirs, textbooks, and research-driven non-fiction — with tools that treat your manuscript as a structured project, not a disposable prompt.
VoxVei is built for long-form work — not blog posts or one-off prompts. Organize chapters in a file tree, open multiple scenes in tabs, and keep research, outlines, and assist files beside your manuscript. Import an existing .docx manuscript or start from a format-aware template for fiction, non-fiction, screenplays, cookbooks, and more.
Generic chatbots forget what you wrote three pages ago. VoxVei indexes every save so your AI co-author retrieves the passages that matter — a character's eye color, a timeline contradiction, a theme you planted in chapter two. Project memory scales with your manuscript, so the agent answers from your story bible, not a blank slate.
Assist files act as a structured database for your world: characters.md tracks cast and relationships, places.md holds settings, timeline.md orders events, and terms.md captures invented language or key concepts. The agent reads and updates these registries as you write, and a one-click review pass checks consistency across every chapter.
Switch between Markdown source, rich-text WYSIWYG, and distraction-free Document mode. Run Live Edit on any selection, generate character portraits, map relationships and chronology, manage citations for non-fiction, and export to DOCX, PDF, or plain text when you're ready to share. Version history, project scan, and background book-wide jobs help you revise without losing momentum.
Need a quick utility without an account? Try our free writing tools — word counter, spell checker, PDF to text, and a browser word editor — then move your manuscript into the full workspace when you are ready to write the rest of the book with an AI that understands and remembers.
Pick a plan and start your novel in minutes — your AI co-author already knows how to read the whole project.
