AmbientMeta

AmbientMeta provides a privacy gateway for applications that use large language models (LLMs), ensuring that sensitive data is detected and protected before it reaches the model. It addresses the challenge of keeping personally identifiable information (PII) and other confidential data out of LLM workflows by acting as an intermediary between an app and any LLM, such as OpenAI, Anthropic, or Gemini. The tool detects and replaces sensitive entities with placeholders in a single call, typically with a latency of around 150 milliseconds, and then can restore the original values after the LLM has processed the sanitized input. Alternatively, it offers a permanent redaction mode for scenarios where sensitive data must be removed entirely, with no recovery possible.

AmbientMeta supports detection of 17 predefined entity types, including names, emails, phone numbers, social security numbers, credit cards, locations, medical record numbers, DEA numbers, IP addresses, and dates of birth. Users can also define custom patterns via the API to suit organizational needs, such as employee IDs or internal codes. The service provides both a reversible 'sanitize' mode for temporary masking and later rehydration, and a 'redact' mode for permanent removal of sensitive data. Session-based PII mapping is ephemeral and never stored permanently, supporting compliance requirements.

Delivery options include a Python SDK, integrations with LangChain, LlamaIndex, and CrewAI, as well as a drop-in LLM proxy and a single Docker image for self-hosted deployments. The platform is designed for compliance, with features such as full audit trails, ephemeral session data, and SOC 2 readiness. It is built to meet HIPAA and GDPR requirements, uses HTTPS/TLS encryption for data in transit, and offers air-gapped deployment for data sovereignty needs. All plans provide access to the full detection pipeline and all supported entity types.

Pricing is structured in several tiers: a free plan with 1,000 API requests and 10 documents per month, a Developer plan at $29/month, a Team plan at $99/month, a Scale plan at $299/month, and an Enterprise option with custom volumes and deployment options. No credit card is required to start, and all plans include both sanitize and redact capabilities along with SDK and API access.
