Lumen Trust Notes
ChatGPT
ChatGPT is fully cloud-based with no local processing; all inputs are handled on OpenAI servers, making data sovereignty low. Its mission centres on broadly beneficial AI, with transparent safety research and a strong free tier that democratises access. Recommended for general productivity, writing, and research — avoid sharing sensitive PII or confidential commercial data.
n8n
n8n's self-hosted option means organisations can run the entire platform on their own infrastructure with zero data leaving their environment, earning a rare High privacy score. Its fair-code open-source model, transparent codebase, and free self-hosted tier make it the most sovereignty-respecting automation platform in this directory. Strongly recommended for data-sensitive organisations, regulated industries, and any team that needs full control over automation data flows.
