🎯 Our verdict

LightOn positions itself as a sovereign generative AI platform tailored for organizations with stringent security, confidentiality and compliance demands. Through Paradigm, businesses deploy a private chat, augmented Enterprise Search (RAG) and agentic workflows connected to their own document bases, without exposing their data to uncontrolled public clouds. On-premise, air-gapped or private cloud deployment options meet the needs of the most critical sectors. In return, LightOn remains clearly oriented toward large accounts and teams with IT resources. For CISOs, CIOs and business leaders seeking a credible European alternative to OpenAI or Anthropic, it’s a strategic solution for industrializing AI while retaining full data control.

❓ FREQUENT QUESTIONS

FAQ — LightOn

Is LightOn suitable for SMEs?

LightOn primarily targets mid-size companies, large accounts and public organizations with high security requirements. A well-structured SME with strong confidentiality needs can benefit, but the solution remains heavier than a simple consumer assistant.

Can you deploy LightOn on-premise?

Yes, that’s one of its major strengths. The Paradigm platform can be deployed on your own servers, in an air-gapped environment or private cloud, so you retain full control over data and can meet your internal regulatory constraints.

Does LightOn offer a chat assistant for employees?

Yes, LightOn includes a private chat based on its LLMs. Employees can ask questions, query the company’s document base and launch AI agents in a secure interface, with fine-grained access rights management.

What integrations are possible with LightOn?

The platform integrates with your document systems and business tools via APIs and connectors. The goal is to plug AI into your internal sources (documents, knowledge bases, business applications) to feed Enterprise Search and AI agents.

How does LightOn pricing work?

Pricing is provided on quote, based on scope, deployment mode (on-premise, private cloud), user volume and support needs. There is no standard small monthly subscription like consumer tools.
