What makes it different
Answers that show their working.
Every Deep Research response is backed by retrieved primary passages. The point is not a smooth paragraph — it is a defensible argument.
Thomas Hobbes
Leviathan, 1651
In the state of nature, where there is no common power, the life of man is "solitary, poor, nasty, brutish, and short" (Hobbes, 1651, ch. XIII, para. 9). This follows from equality of ability and equality of hope: when two men desire the same scarce thing, they become enemies (ch. XIII, para. 3).

How it works
A supervision loop, not a search box.
01 · Choose
Pick a thinker or topic
Start with a figure, a pathway, or a problem. Trivium selects the relevant corpus and historical frame.
02 · Argue
Get challenged Socratically
The response is not generic help. It pushes claims, asks for distinctions, and cites primary text.
03 · Improve
Turn discussion into writing
Use the conversation as essay prep, then get feedback on structure, evidence, objections and style.
Why Trivium
Built for intellectual discipline.
Trivium is deliberately constrained: grounded in primary texts, bounded by each thinker's lifetime, and honest when the evidence is thin.
No invented citations
Answers cite chapter, paragraph and page where available. If a passage cannot support the answer, it should not appear as evidence.
Era-bounded minds
Marx does not discuss the USSR. Hobbes does not reference Rawls. Each mind knows what it could plausibly have known.
Cambridge study logic
Read, discuss, write: the supervision rhythm adapted for students who need rigorous prep without a private tutor.
