How is Lumis different from Particle?

Lumis synthesizes multiple AI/tech research sources (Hacker News, arXiv, The Batch, Latent Space) into a single daily briefing delivered to your inbox. Particle focuses on AI-powered personalized news. Lumis works passively — you receive your briefing each morning — while Particle 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 Particle?

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