Every tier sees current, correct data — nobody's score is delayed and nobody's rank is stale. What changes tier to tier is how finely you can watch a number move (yearly, monthly, daily) and how much structure you can get into once you're looking at it (seeing that a cluster exists, reading what's inside one, or being told the moment it changes).

A research packet is a markdown briefing you create from any cluster, element, or reading list in Elements Live. It includes the papers, scores, and structure behind what you're looking at — formatted so you can drop it straight into Claude, ChatGPT, or any LLM to continue the research conversation without retyping.
Creating a packet costs one credit. Free and Personal users get a monthly allowance (15 and 25 credits respectively) — more than enough for one packet per weekday. Sharing a packet is always free. If someone creates an account through your shared link and upgrades to a paid tier, you earn credits as a referral bonus — so your best research can pay you back. Professional and Enterprise users have no creation limits.
Research Intensity Score: a 0-to-1 read on how much of the world's current scientific attention an element holds, weighted by how much its recent papers are actually being cited — not just how many came out.
No. Every tier, including Free and logged-out browsing, sees the same current RIS and rank for every element. Nothing is held back or shown late — what differs tier to tier is resolution and depth, not freshness.
Yes, and it never expires. The full interactive periodic table, all 118 element pages, current scores and ranks, the 100-year arc, velocity, the 10-year trends report, and browsing up to 100 papers per element are all open with no account and no credit card. Creating a free account adds favourites, paper bookmarking, and a first research packet.
Yes — it's month-to-month with no lock-in. Cancel from your account page and you'll keep access through the end of the period you already paid for.
