How is Lumis different from Perplexity?

Lumis synthesizes multiple AI/tech research sources (Hacker News, arXiv, The Batch, Latent Space) into a single daily briefing delivered to your inbox. Perplexity focuses on The AI-native answer engine. Lumis works passively — you receive your briefing each morning — while Perplexity requires more active engagement.

What does Lumis cost?

Founding members lock in at $9/mo — a fraction of most comparable services. That's 499 of the first 500 founding spots remaining before pricing increases.

Does Lumis cover the same sources as Perplexity?

Lumis synthesizes Hacker News, arXiv cs.AI, deeplearning.ai (The Batch), and Latent Space — the original research signals, not newsletter summaries of them. If Perplexity covers these sources, Lumis brings them together into one ranked, AI-synthesized briefing.

If you currently use Perplexity

What changes with Lumis: Lumis delivers yesterday's research to your inbox so you start every morning informed — no active search required. Perplexity is great for active queries; Lumis is better for passive monitoring.

What Perplexity does better: Perplexity is an AI-powered search engine that answers questions in real-time with cited sources. Excellent for ad-hoc research, less suited for daily monitoring.

Comparison searches are the warmest intent on the web — you're mid-evaluation, not browsing casually. Lumis is built for the researcher who wants the signal without the overhead. Lock the founding price before the first 500 spots fill.
