Westlaw returns a list. LexEra returns a navigable network of every case, statute, regulation, judge, and doctrine — read by a Claude agent that can reason across all of it at once.
Every feature below is a first-class primitive in LexEra's knowledge graph — not a search result re-ranked by a bolted-on language model.
Nine million opinions wired into a single traversable network. Find the path from Chevron to Loper Bright in one query instead of three days.
Every federal judge's financial disclosures linked to the cases they ruled on. Ideology, reversal rate, and conflicts you didn't know existed.
Which CFR sections were never litigated in the 9th Circuit? Compliance consulting in one query instead of six figures.
Upload a brief drafted with ChatGPT or Claude. Every citation verified against real law — existence, holding, and treatment — before you file.
KeyCite gives you a flag. LexEra shows the exact passage where the overruling happened, the vote split, the dissenters, and why it matters for you.
Describe intent, get a brief with live citations to cases in the graph — every clause linking back to the primary source it's based on.
Heavy researchers typically pay $100–$150. Still less than half of Westlaw's floor — with no annual contract, no sales call, no vendor lock.
Flat. You bring your Anthropic key.
$50 base + Anthropic cost + 10% markup.
