Nonym
What it is
Nonym is a privacy layer placed between an app and SaaS vendors. Its AI Proxy detects personally identifiable information (PII) in prompts, replaces it with structured tokens before sending the request, then restores the values in the response before it reaches the app. Detection uses named entity recognition and covers items such as names, email addresses, phone numbers, SSNs, credit card details, API keys, and addresses. The proxy works with OpenAI, Anthropic, Google AI, and OpenAI-compatible APIs, with streaming response support. Nonym states that processing adds under 20ms overhead. Requests can be logged with detection counts, PII types, and confidence scores; a full audit trail is listed for paid plans. The pricing FAQ says managed Cloud token mappings are held in memory during a request and never written to disk. Community is free for non-commercial self-hosting. Cloud costs $49 per month plus $0.50 per 10K requests, while the Self-Host License costs $99 per month. Enterprise uses custom pricing starting ~$2,500/month and lists private VPC and air-gapped deployment options. Questionnaire Automation drafts cited answers from uploaded documents, but is in active development.
