NXTG.ai builds products that check AI's work before you rely on it.

Faultline

Faultline checks the claims and citations in AI output against real sources, across multiple AI providers, and maps the findings to frameworks like the EU AI Act and NIST AI RMF.

Faultline Enterprise

Faultline Enterprise is the full platform: a REST API with key management and multi-tenant usage, an MCP server and a Python client, deployed with your rollout, a Terraform provider and a GitHub Action, multi-model consensus verification, a tamper-evident audit log, a risk register and human sign-off (mapped to EU AI Act Articles 9, 12 and 14), custom frameworks and dedicated support.

Plans are Free, Personal ($19/mo), Pro ($49/mo) and Enterprise (custom), at faultline.nxtg.ai/pricing. Alpha: limits and features may change; no SLA.

Faultline Enterprise Rollout

Faultline Enterprise Rollout: in 4 weeks we deploy Faultline Enterprise in your stack, wire it into your AI and agent pipelines, set the checks with your team, and hand over a running system with an audit trail.

Includes the Faultline Enterprise subscription. Pricing on request.

For developers

The Faultline CLI is open source on npm as @nxtg/faultline (Apache-2.0) and in alpha.
