Every answer is drawn from your own material and cites the exact page — click the citation to jump straight there. No made-up facts, no guessing what a slide said.
For logistic regression, the in-sample error is
Ein(w) = 1/N Σ ln(1 + e^(−yₙwᵀxₙ))
which gradient descent minimizes iteratively.
Most tools dump your document into a prompt and hope. StudyThread is a system built around your material — so answers stay grounded, fast, and cheap.
Everything you upload is embedded and searched by meaning, so it surfaces the right passage even when you don't use the exact words on the page.
The model works like a research assistant, not a chatbot — it reads pages, searches across documents, and cites what it used, with tool budgets that keep it honest.
Prompt caching and smart model routing send easy questions to a lighter model and hard ones to the strongest — so it stays quick without burning tokens.
Every claim links to the page it came from — verify in one click.
Save any passage, annotate it with rich text and LaTeX, and ask about just that excerpt.
Turn a document into a study set — multiple choice or short answer, editable and expandable.
Jump in and look around — no account needed to start. Upload a document and you'll be asking it questions in under a minute.
