Nonym is a privacy layer between an app and SaaS services, designed to remove personally identifiable information before it reaches providers and support data rights and compliance audit trails. Its AI Proxy uses named entity recognition to find items such as names, email addresses, phone numbers, postal addresses, SSNs, payment card details and API keys. It replaces detected values with structured tokens before sending a prompt, then restores those values in the response before returning it to the app. The proxy supports OpenAI, Anthropic, Google AI and OpenAI-compatible APIs, including streaming. Nonym states processing adds under 20ms overhead. Request logs can record detection counts, PII types and confidence scores; a full audit trail is available on paid plans. Managed Cloud token mappings are held in memory for the request and not written to disk. The service supports API, self-hosted and web use, with private VPC and air-gapped options for Enterprise. Community is free for non-commercial self-hosting. Cloud costs $49/mo plus $0.50 per 10K requests; Self-Host License is $99/mo. Enterprise pricing is custom, starting around $2,500/mo.
