What our research says

AnswerThis

AnswerThis goes further into the actual review process than most cited-answer tools — dual-reviewer screening, evidence grading and PRISMA structure are real workflow features, not chat wrappers. The catch is price: $35 a seat is well above general research assistants, and the free tier's five-project cap makes a serious evaluation awkward.

Pros

Screening, evidence grading and drafting sit in one workflow
Free plan needs no card and still includes cited search and exports
Exports into standard reference managers and thousands of citation styles
Institutional tier covers SSO and LMS integration rather than just more seats

Cons

Corpus size is stated inconsistently: 300M+ papers on the homepage, 250M+ on the pricing page
Team tier requires three seats billed annually, so the real entry cost is much higher
No API for pulling results into other tools

SciSpace

SciSpace is the broadest of the paper-reading tools: search, explain, compare, extract, review and write all live in one account, which suits a student or early-career researcher who wants one subscription rather than four. The trade-off is depth: Elicit and Consensus are more careful about evidence quality, and the AI writer, paraphraser and humaniser push the product toward producing text rather than understanding it, which is where academic-integrity trouble starts. The free account is enough to judge the explainer; the $12 annual Premium is cheap, but credits run out quickly on heavy chat use.

Pros

Index of 270M+ papers with question-based search, explainers, comparison tables and data extraction in one workspace
Chrome extension explains PDFs wherever you read them
Free account to test the explainer, and Premium at $12 a month on annual billing
Agent templates chain search, review and extraction for recurring tasks such as grant or clinical lookups

Cons

Premium is credit-metered at 1,200 credits a month, and unlimited use starts at $70 a month annually
The AI writer, paraphraser and humaniser sit uneasily with academic-integrity policies
The site challenges automated readers and the terms render client-side, so the legal entity is not visible
Summaries can smooth over a paper's caveats; the source still has to be read for anything that matters
