Features No Other Writing Tool Has
Real version control, structured review workflows, and privacy-first AI — all in one platform
AI Writing Assistant
Tracks your storyline, checks for plot holes, suggests directions, and manages character consistency. Reads your entire manuscript and notes. Never writes for you. Powered by Vertex AI — your data is never used for model training, unlike tools built on consumer APIs.
Learn moreVersion Control for Writers
The only writing platform with real branches, merging, and visual diffs. Explore alternate paths without risking your main draft. No other tool — Scrivener, Dabble, Novlr, or Google Docs — offers this.
Learn moreZen Mode
Five immersive full-screen environments — from midnight starfields to warm firelight. Far beyond the basic "hide the toolbar" distraction-free modes in other tools. Auto-hiding UI, animated atmospheres, pure focus.
Learn moreComplete Data Privacy
Powered by Google Vertex AI — your writing is contractually guaranteed to never be used for model training. Most writing tools use consumer AI APIs with unclear data policies. We chose differently.
Learn moreProfessional Publishing
Export print-ready PDFs with professional typography. Title page, table of contents, proper chapter formatting. Your book looks published.
Learn moreReviews & Collaboration
Request feedback on drafts with line-by-line diffs, threaded comments, and approve/reject workflows. A structured review process no other writing tool offers — built for co-authors, editors, and writing groups.
Learn moreFor Every Kind of Writer
Prongs adapts its entire interface to your creative format.
Every Word, Protected
Writers lose sleep over lost work. We built Prongs so you never have to.
Auto-Saved, Always
Every keystroke is saved automatically. No manual saving, no risk of losing work. If your browser crashes mid-sentence, your words are still there when you come back.
Full Version History
Every checkpoint you save is preserved forever. Deleted a chapter last week and want it back? It's there. Changed your mind about a rewrite? Roll back in one click.
Private by Contract
Your unpublished manuscript is sensitive. Prongs uses Google Vertex AI — your writing is contractually guaranteed to never train AI models. No other writing tool makes this promise.
