Privacy-First AI

Your Words Are Never Used to Train AI

Dabble, Novlr, LivingWriter, and most AI writing tools send your work to consumer APIs where it may be used for model training. Prongs is different. We use Google Vertex AI — your data stays in Google's enterprise infrastructure and is contractually guaranteed to never be used to improve models. No other writing tool makes this promise.

Why Vertex AI Matters

Most AI Writing Tools

  • Your writing sent to consumer API endpoints
  • Data may be used to train future models
  • Content potentially reviewed by human contractors
  • Unclear data retention policies
  • Your unpublished manuscript in someone else's training data

Prongs with Vertex AI

  • Data processed within Google Cloud infrastructure
  • Your content is never used for model training
  • Enterprise-grade security and compliance
  • Clear data handling — processed and discarded
  • Your unpublished work stays completely private

How We Protect Your Creative Work

Encrypted in Transit and at Rest

All data is encrypted using TLS in transit and AES-256 at rest within Google Cloud. Your manuscripts, notes, and conversations are protected by the same infrastructure that secures Gmail and Google Docs.

Firebase + Cloud Storage

Your documents live in Google Firestore with per-user access rules. Version snapshots are stored in Google Cloud Storage. No third-party databases or storage providers touch your data.

No Third-Party Analytics on Content

We don't run your writing through any analytics, classification, or content moderation services. We don't read your work. We don't index it. We don't profile you based on what you write.

Your Data, Your Control

Export your work at any time. If you cancel your subscription, your data is preserved — not deleted. You can come back and access it whenever you want.

Why This Matters for Writers

Your unpublished manuscript is valuable intellectual property. An unfinished novel, an unreleased screenplay, confidential research — these deserve the same protection as any trade secret.

When you use a consumer AI API, your writing may become part of a training dataset. That means fragments of your unpublished work could theoretically influence model outputs for other users. For most writing tools, this is the fine print nobody reads.

Prongs chose Google Vertex AI specifically because it offers a contractual guarantee: customer data is not used for model training. This isn't a policy that could change with a terms-of-service update — it's baked into the enterprise agreement.
