Perplexity AI
Perplexity is an AI answer engine that combines LLMs with live web search to return cited, conversational responses for research and everyday queries.
Independent assessment across data handling, compliance, security and transparency.
Overview
Perplexity AI is a conversational answer engine that fuses large language models (GPT, Claude, Sonar, Grok) with real-time web retrieval, returning sourced answers with inline citations. The product suite spans web, mobile, Comet browser, and Sonar API. Enterprise Pro adds SSO, SOC 2 Type II attestation, a zero-retention policy for customer prompts, and a contractual ban on using enterprise data for model training. Consumer Free and Pro tiers permit Perplexity to use prompts for product improvement unless the user opts out in settings.
Risk factors
2- Consumer tiers allow data usage for model training.
- Potential for sensitive data exposure in prompts.
Recommendations
2- Enhance user opt-out options for data usage.
- Provide clear communication on data handling practices.
Data handling
- Storage
- Cloud-hosted on US infrastructure; uses multiple model providers (OpenAI, Anthropic, Meta, xAI) as subprocessors. Enterprise tier offers isolated processing.
- Retention
- Consumer prompts retained to power history and personalization until user deletes. Enterprise Pro and Sonar API offer zero data retention on request.
- Training on inputs
- Consumer tiers may use prompts to improve models unless users opt out. Enterprise Pro contractually prohibits using customer data for training.
