Your Creative Process, Managed
Prongs AI doesn't write your story. It helps you manage everything around it — storylines, character consistency, plot holes, research, and creative direction. All powered by Vertex AI with guaranteed privacy — your data is never used for training, unlike tools built on consumer APIs. You stay in the driver's seat.
Try It Free for 14 DaysWhat the AI Assistant Actually Does
Built-in quick actions plus free-form conversation, all aware of your full document, chapters, and notes.
Summarize Sections
One click to get a summary of any chapter or section. Identify key themes, turning points, and narrative arcs at a glance.
Suggest Directions
Stuck? Ask for continuation suggestions. Get 3+ story directions with example paragraphs for each — then choose the one that resonates.
Check Consistency
Find plot holes, character inconsistencies, and timeline contradictions across your entire manuscript. The AI reads every chapter.
How It Works
Context-Aware by Default
The AI automatically sees your full document structure, the chapter you're currently editing, and all your research notes. No need to copy-paste context — it's already there.
Conversation, Not Commands
Have a real back-and-forth conversation about your work. Ask follow-up questions, refine ideas, explore alternatives. Every conversation is saved so you can revisit it later.
Save Insights as Notes
Found a useful AI response? Save it as a research note with one click. Those notes then feed back into future AI conversations — building a growing knowledge base for your project.
Built for Real Writers
Multi-Turn Conversations
Real back-and-forth dialogue about your work. Not single-prompt, single-response.
Voice Input
Speak your questions naturally. Web Speech API converts your voice to text in real time.
Notes Integration
All your research notes are included as AI context. The more notes you add, the smarter it gets.
Streaming Responses
See the AI think in real time. Responses stream word by word — no waiting for a wall of text.
Quick Actions
One-click summarize, continue, and consistency check. No prompt engineering required.
Private by Design
Powered by Google Vertex AI. Your writing is never used to train models or shared with third parties.
Your Words Stay Yours — Guaranteed
Most writing tools with AI features use consumer APIs where your unpublished manuscript may end up in training data. Dabble, Novlr, and LivingWriter offer no clear guarantees. Prongs uses Google Vertex AI — an enterprise-grade platform where your data is contractually guaranteed to never be used for model training. Your manuscript, your notes, your conversations — they're private. Always.
