Daxa.ai Pebblo vs Private AI PrivateGPT Headless: Side-by-Side Comparison (2026)

Daxa.ai Pebblo

Security teams deploying retrieval-augmented generation chatbots need Daxa.ai Pebblo because it stops data poisoning and prompt injection at the retrieval layer before malicious inputs ever reach your model. The dual-layer architecture covers both Safe Infer (real-time redaction) and Safe RAG (authorization-aware vector database queries), which directly addresses NIST PR.DS and DE.CM requirements that most RAG platforms skip entirely. Skip this if your organization isn't actively using LLMs with external data sources; Pebblo's value evaporates without that specific architecture.

Private AI PrivateGPT Headless

Organizations sending sensitive data to ChatGPT or other LLMs without an on-premises filter should evaluate Private AI PrivateGPT Headless, which detects and strips 50+ PII types before API calls leave your network, then restores them in responses without external data leakage. The on-premises deployment and HIPAA/GDPR/PCI DSS compliance support matter here; you're not trusting a vendor's promise that data won't be retained by OpenAI. Skip this if your use case doesn't involve third-party LLMs or if you need re-identification logic that handles complex, domain-specific entities beyond the standard PII set.
