AnswerThis is a web-based AI research assistant for people who work with academic literature. Users ask a question, paste a protocol or upload a draft, and the platform searches its database of research papers and returns answers with citations that can be verified. The site cites a database of 250M+ papers on some pages and 300M+ on others.
The company says it is backed by Y Combinator and used by more than a million researchers. Its pitch is aimed at problems such as screening thousands of papers by hand, receiving made-up citations from general chat tools and juggling many apps to write a single paper.
The workflow runs through five stages that write into the same cited document: Canvas, Library, AI Writer, Share and Systematic Review. In Canvas, users enter a question and filter by database, journal quality, date and study type. Each answer has clickable citations that jump to the exact passage in the source paper.
AnswerThis says it checks every statement against the paper it came from before showing it, and removes anything it cannot trace to a real source. The company describes this as verification rather than guessing or filling gaps.
Results then move to the Library for organizing, the AI Writer for drafting, and shared workspaces for co-authors, with no exports between tools.
The core tools are cited search, a reference library with collections, tags, highlights and full-text search, and an AI Writer. The writer can import an existing draft, cite from the library in one click, detect AI-generated text or plagiarism, and switch between more than 2,000 citation styles.
For evidence synthesis, the platform covers screening, extraction, meta-analysis and grading with a logged audit trail. Advanced options include fixed or random-effects pooling, network meta-analysis with SUCRA rankings, GRADE certainty ratings, and forest and funnel plots.
Industry users get Trial Landscape, which maps trials from live registries by phase, sponsor and endpoint, and connectors for regulatory filings and medical databases.
AnswerThis is an AI research assistant that searches a large database of academic papers and returns cited answers. It also helps draft literature reviews and run PRISMA-compliant systematic reviews.
The Free plan is $0 per month with no card required. Pro is listed at $35 per seat per month, Lab & Team at $75 per month billed annually with a 3-seat minimum, and Max at $250 per month. The site shows a 17% saving for yearly billing, and a comparison table lists other figures, so check the current page.
Yes. The Free plan includes deep search across 250M+ papers, cited answers and summaries, 5 saved projects and export to Zotero, Mendeley and EndNote. No card is required.
It suits students, academics, research labs, university libraries and industry teams in HEOR, pharma and CROs. It is most useful for people who run literature reviews or systematic reviews.
It syncs with Zotero, Mendeley and EndNote, and can search PubMed, Embase and Cochrane in one query. Enterprise and institutional plans add SSO/SAML and LMS integration.
The company says each statement is checked against the source it came from, and unsourced claims are removed. Citations link to the exact paper and passage, though users should still review important claims.
The site states that papers, drafts and libraries are never used to train models. It also says data is encrypted in transit and at rest.
Yes. It offers screening, extraction, meta-analysis and grading with a logged audit trail, and describes the workflow as PRISMA and Cochrane compliant. Dual-reviewer pipelines appear on the Lab & Team plan.
