Privace.ai vs Gretel.ai
Differentially private synthetic data generation (now part of NVIDIA NeMo).
What Gretel.ai does
Gretel.ai builds synthetic data with differential privacy — generating realistic datasets that retain statistical properties without exposing real records, for training and sharing. Following its NVIDIA acquisition, its capabilities are being delivered through NeMo microservices (Data Designer and Safe Synthesizer).
How Privace.ai differs
Gretel is a data-generation platform for ML teams. Privace.ai is a real-time privacy gateway for anyone using public LLMs: it redacts the actual sensitive values a user types, restores them in the answer, and enforces sector policies with BYOK and audit — a runtime control, not a dataset generator.
Privace.ai vs Gretel.ai: capability comparison
A fair, side-by-side look at the seven dimensions that define an LLM redaction gateway.
Reversible redaction — restore originals in the LLM response
Admin-owned sector PII / PHI / PCI libraries
In-LLM-input interception (browser extension, before submit)
Strict BYOK — your own LLM key, keys never shared
Single-perimeter, GCP-native data sovereignty
LLM-as-a-Judge output scoring
Token-only, fully auditable trail
Comparison reflects publicly documented capabilities at time of writing and each product's primary design intent; vendors evolve quickly — verify specifics for your use case.
Privace.ai vs Gretel.ai — FAQ
- Is Privace.ai a Gretel.ai alternative?
- Only loosely — they address different needs. Gretel generates privacy-preserving synthetic datasets; Privace.ai redacts and restores real sensitive data in live LLM prompts. If your goal is safe ChatGPT/Claude use, Privace.ai is the fit.
- Does Privace.ai create synthetic training data?
- No. Privace.ai focuses on real-time redaction of prompts to public LLMs with reversible restore, sector policies, BYOK and audit — not synthetic dataset generation.
- Is Gretel still available standalone?
- Gretel was acquired by NVIDIA and its capabilities are moving into NeMo microservices. Privace.ai is an independent, GCP-native product focused on the LLM privacy gateway.

Install the extension and watch PII, PHI and PCI get redacted before ChatGPT, Claude or Gemini ever see it — then restored in the answer. No credit card required.
