Background: Hypertension affects 1.3 billion adults worldwide. This RCT evaluated the effect of 12-week aerobic exercise on blood pressure in 180 adults with stage 1 hypertension.

Dual AI
GPT-4o + Claude
6 Steps
Import to synthesis, fully guided
THE PROBLEM
A single systematic review can take 6–18 months. Researchers spend hundreds of hours manually screening thousands of abstracts, extracting data from PDFs, and assessing risk of bias — work that is repetitive, error-prone, and delays the translation of evidence into clinical practice.
Traditional tools charge per review and offer no AI assistance. Spreadsheets are unstructured and don't scale. The process hasn't changed in decades — until now.
Screening 2,000 abstracts manually takes weeks of work
Traditional tools charge $160+ per review with no AI included
Manual processes introduce inconsistency and bias
From import to synthesis, every step is assisted by state-of-the-art AI.
Import RIS, BibTeX, CSV, or XML from any database. GPT-4o and Claude screen every record in parallel. Accept AI decisions or override them — you make the final call.
Upload PDFs individually or in bulk. Claude Haiku reads and screens each full text against your inclusion criteria (alongside GPT-4o). Includes confidence scores and reasoning.
Define your extraction fields once. AI fills them from every included study. Side-by-side GPT vs Claude comparison with one-click consensus approval.
Supports RoB2, ROBINS-I, CASP, and Newcastle-Ottawa Scale. AI suggests the appropriate tool based on study design and runs a full dual-model assessment.
Automatically generated PRISMA 2020 flow diagram. Updates in real time as you screen. Export as PNG for publication.
Export your data as CSV, Excel, or Word. Generate a structured report ready for your manuscript. All decisions logged in a full audit trail.
HOW IT WORKS
Upload your search results from PubMed, Embase, Cochrane, or any other database. Supports RIS, BibTeX, CSV, and XML. Automatic duplicate detection removes redundant records.
Drop PDF or RIS here
AI screens every title and abstract against your inclusion and exclusion criteria. Two independent AI models vote on each record. You review conflicts and make final decisions with keyboard shortcuts.
Upload PDFs for included studies. AI reads the full text and applies your criteria at a deeper level. Bulk upload with automatic title matching saves hours of manual work.
Define the variables you want to extract. AI reads each PDF and populates your data table. Review the AI output, make corrections, and approve the final dataset.
AI selects the appropriate RoB tool for each study type and runs a structured assessment. Review domain-by-domain judgments with AI rationale and supporting text.
Generate an AI synthesis of your findings, export a PRISMA flow diagram, and download your complete dataset. Your review is ready for writing.
