Elicit vs Synthesis

Elicit is an AI research assistant for researchers gathering and assessing evidence. Its Research Agent draws on scientific databases, academic journals, public data sources, uploaded documents, a corpus of 138 million academic papers, and the wider web. A session can use up to 20 uploaded resources, including PDF, DOCX, XLSX, PPTX, and JPG files. Elicit offers Research Agent sessions, Research Reports, and Systematic Reviews, and supports AI-generated claims with sentence-level citations to underlying sources. It can find up to 1,000 relevant papers and analyze up to 20,000 data points at once. Research Reports export as PDF or Word, tables as CSV or Excel, and references as RIS or BIB. Elicit runs on the web and provides an API, but API access requires Pro or above. Its MCP server connects to Claude Desktop, Claude Code, and other compatible clients using OAuth 2.0. Basic is free with limited usage for Research Agent and Research Reports; Plus costs $11 a month. Pro is $39 a month and Scale is $89 a month. Elicit states that it has achieved SOC 2 Type II compliance.

Synthesis is software for conducting scoping, systematic and regular literature reviews. It organizes references and PDFs, searches abstracts and full-text PDFs by keyword or phrase, and automatically de-duplicates imported references. The support page reports externally validated deduplication sensitivity of 98% and specificity of 99%. Its screening workflow supports primary and secondary reviewers working through abstracts and full text, with kappa scores calculated for both. Analysis tools include AI-assisted topic clustering, word clouds, metadata extraction and charts. Embedded searches cover PubMed, PubMed Central, IEEE, arXiv.org and US Patents; references can also be imported from Ovid, Web of Knowledge, ProQuest and ACM. Synthesis can download many full-text PDFs when open or institutional access is available, and exports references and data as RIS and CSV. The trial allows unlimited projects, but each project can import only 50 references and uses a slower PDF viewer. The maker says orders and downloads are temporarily suspended during development of a new release. Licenses are tied to individual computers; pricing is available on request.
