A real Debate-mode answer from RepSearch. Every point links to the study it came from, and every quote is checked word for word.
DEBATE MODE · LATER SCHOOL START TIMES
EVIDENCE FOR
California's statewide mandate for later school start times increased the share of students sleeping at least 8 hours per night by 13%, and grade 8 math and English scores rose by 0.08–0.10 standard deviations. [3]
A systematic review of 17 reports across 6 countries found later start times increase sleep and are linked to better academic and psychosocial outcomes. [7]
“Later school start times appear to increase sleeping time. And there is a positive association between later school start times and academic and psychosocial outcomes.”
EVIDENCE AGAINST
In a South Korean study, the extra sleep shrank from 19 minutes to only 7 minutes a year after the change and was no longer statistically significant. [6]
For elementary students, start times had near-zero effects on test scores, so the benefits may not apply to every grade level. [9]
“Regarding academic outcomes, our estimates are small in magnitude and suggest that earlier elementary start times have near-zero effects.”

NO HALLUCINATED SOURCES
Most AI chatbots answer from memory, so they can invent facts, quotes and even whole studies. RepSearch works differently: it only answers from real sources it just found, and checks its own work before you see it.
The AI can't browse the web. It only reads what RepSearch pulls from OpenAlex, PubMed, ERIC, arXiv, the Congressional Research Service, the Federal Register, court records and other reputable sources. No blogs, no forums, no content farms.
Each point has to cite the numbered source it came from. If a point doesn't cite a real source, it gets deleted before you ever see it.
Every quote is matched against the actual abstract or paper text. If the words aren't really there, the quote is removed.
A separate AI re-reads the sources and checks each point. Points the sources don't support are removed, and points credited to the wrong study are fixed.
If the sources don't answer your question, RepSearch tells you instead of guessing.
No AI is perfect, so every claim links straight to its source. Click through and read it before you cite it.
Type a topic once. We pull peer-reviewed studies, academic papers and trusted reporting into one list, so you don't have to search ten sites.
No random blogs or content farms. Every result shows who published it, when, and links to the original so you can check it yourself.
The research assistant only answers from the sources it found and cites each claim. If it can't find good evidence, it tells you instead of guessing.
