Research software, in context

Compare the research workflow, not only the feature list.

Specialist tools can be excellent at one stage. This comparison shows where each product is strongest and what changes when the entire study needs to remain connected.

Compare the workflow

Built to connect the study, not only one stage.

Specialist tools can be excellent at the job they were designed for. SixSentences_ is different when the hand-offs matter: the paper you screened, the passage you verified, the dataset you analysed and the claim you write remain part of one record.

The honest distinction.

Elicit is a strong choice for large AI-assisted evidence workflows. Its new Research Agent can also analyse uploaded scientific files, create plots and generate images. That is a meaningful expansion, but it is not positioned as a survey or interview collection system, nor as a LaTeX manuscript editor.

Prism is purpose-built around collaborative LaTeX authoring. Rayyan and Covidence offer mature specialist processes for review teams. SixSentences_ is in closed beta: its advantage is connected breadth and study-wide provenance, not a claim that every module already replaces the deepest specialist workflow.

If your work stops at one stage, a specialist may be the better fit. If the costly part is moving context between stages, that is the problem SixSentences_ is built to solve.

Comparison reflects publicly documented product positioning reviewed on 25 July 2026 and is not an exhaustive feature audit. Product scopes change; follow each product link for current capabilities.

Coverage totals are not like-for-like: OpenAlex's 317 million records span 19 work types, including articles, conference papers, books, datasets and theses. Elicit reports 138 million academic papers and conference proceedings in its own corpus. Neither number represents that many available full-text PDFs.
