Lumen Trust Notes
Perplexity AI
Perplexity processes all queries on cloud infrastructure with no local option, keeping sovereignty low. Its transparent citation model and a genuinely useful free tier represent both an ethical commitment to honest information and broad access parity. Strongly recommended for research, fact-checking, and staying current — treat it as a research assistant, not a replacement for primary source verification.
Lection
The Lection service presents significant technical sovereignty concerns due to its reliance on cloud processing without explicitly stating local-only options or end-to-end encryption for user-scraped data. Transparency is critically lacking regarding the provenance of its AI models, user data handling ethics, and any commitments to bias mitigation or accessibility standards.
