What you're actually getting
Not feature flags — real workflows that save you time every week.
Personal sources
Point Lumis at the feeds you care about.
Add any URL — blog, newsletter, Substack, company engineering blog. Lumis auto-discovers the RSS feed and blends it into your morning briefing under "From your sources."
Weekly recap
Every Friday, the week's signal compressed.
Your personal top 5 insights ranked by authority score and your own feedback. A separate digest — not another daily briefing. 5 minutes. Nothing missed.
Full trending view
See what's moving, not just today's three.
The free tier shows 7-day trending. Pro unlocks 24h (what blew up overnight) and 30d (slow burns that compound). The difference between catching a wave and reading about it.
From the waitlist
A few things they told us along the way.
"I used to spend 45 minutes every morning skimming Twitter and newsletters for what mattered. Lumis does that for me before my first coffee. The weekly recap is the thing I didn't know I needed."
"The personal sources feature is the unlock. I pointed it at three internal blogs and two substacks I've been meaning to follow — now they're in my briefing automatically. It's like having a research assistant that actually reads everything."
"I work across four AI topics and the topic subscriptions let me turn off the noise. I only hear from Lumis when something actually moves in my area. That's rare from any newsletter."
FAQ
How is this different from a newsletter?
A newsletter has one author's perspective, published on their schedule. Lumis monitors four live sources daily — HN, arXiv cs.AI, The Batch, and Latent Space — synthesizes the top signals through an LLM, and delivers them ranked by what actually matters. No opinion column. No sponsor slots. Just what moved in AI today.
Can I cancel anytime?
Yes. Cancel from your Stripe billing portal whenever you want. Your Pro features stay active until the end of the current billing period. No questions, no retention flows.
What happens to my data if I downgrade?
Your personal sources and topic subscriptions are paused, not deleted. If you resubscribe, everything picks up where you left off. Your archive access and briefing history remain intact.
Is there a free trial?
No trial — but the free plan is fully functional and stays free forever. You get the daily briefing, archive access, and trending (7d). Upgrade when the Pro features are worth $15/month to you.
Do you offer team plans?
Not yet. If you need 5+ seats, email us and we'll work something out.
How does personal source monitoring work?
You add any URL from your /sources dashboard. Lumis auto-discovers the RSS or Atom feed. It checks your sources nightly alongside the global pool. When something from your feeds makes the cut, it appears under "From your sources" at the top of your briefing. Up to 10 active sources.
Every morning. Your sources. Your topics. Your signal — not the crowd's. $15/month. Cancel whenever.
Payment via Stripe. Secure checkout. Cancel anytime.
