Built specifically for regulated organizations, Liminal is the platform that finally makes enterprise-grade AI both powerful and safe. Unlimited, Secure, Multi-Model AI Stop choosing between productivity and security. Liminal delivers unlimited access to the latest AI models and agents, so your teams can use the best tool for every task — with no usage caps, no vendor lock-in, and no compromise on data protection. Bring your own fine-tuned or proprietary models and run them alongside top providers in one unified, secure environment. Complete Data Protection Without the Friction Liminal's powerful data protection engine automatically detects sensitive information in prompts before it ever reaches an AI model. PII, PHI, PCI, trade secrets, IP — Liminal identifies it, applies your security policies (mask, redact, warn, or allow), and then rehydrates protected terms in the response so users get full, seamless value. Most solutions just redact. Liminal preserves context. Total AI Governance in One Central Hub Give your security and privacy teams the oversight they need. Liminal's centralized governance hub provides granular access controls, real-time observability, and instant alerting so you always know what's happening across every AI interaction in your organization. Set policies once and enforce them everywhere. All Your Data. One Secure Platform. Your organization's knowledge shouldn't be locked away from your AI. Liminal's enterprise search and RAG capabilities connect AI interactions to your internal data (whether it lives in Google Workspace, Microsoft 365, local systems, cloud environments, or anywhere else) so your teams get accurate, verifiable answers grounded in your actual organizational context. Source attribution and dynamic re-ranking ensure responses are up-to-date and trustworthy, while governance-aware access controls mean users only surface data they're authorized to see. Sensitive information is protected end-to-end, within a dedicated single-tenant architecture. Your data powers your AI, and stays completely under your control. Custom Multi-Model Assistants Build and deploy personalized AI assistants tailored to your organization's unique workflows and security requirements. Configure with natural language, file uploads, and internal data connections. Let Liminal auto-select the best model for each task, or choose your own.
