Synthesis Lab
AI literature review and evidence synthesis
Synthesis Lab builds evidence matrices where every cell is a verified extraction with a source span, then clusters themes, runs PRISMA-grade screening, and keeps your review alive as new papers arrive.
What Synthesis Lab does
Evidence matrices, verified
One row per paper, one column per question: every filled cell is extracted from full text, carries its source span, and is fact-checked before you see it.
Critical appraisal built in
ROB2, GRADE, or CASP presets score each study with quoted justifications, and claims supported only by low-quality evidence are flagged separately.
PRISMA-grade reviews
Inclusion criteria, per-paper screening decisions, and the flow diagram: the systematic-review workflow examiners expect.
Theme synthesis you can defend
Themes, gaps, and a drafted narrative whose every claim links back to matrix cells, with live verification verdicts, never invented support.
A living review
New papers matching your saved searches queue for screening: accept to extract into the matrix, dismiss to record the decision.
Grounded by design
Synthesis claims are built only from verified matrix cells. The narrative can't say what the evidence table doesn't hold.
Who Synthesis Lab is for
Students writing a literature review chapter
Synthesis is grounded in papers you actually collected, with every claim carrying a verified citation.
Systematic reviewers working to PRISMA
Screening decisions are logged, counts tracked, and a real PRISMA flow diagram is produced for your methods section.
Anyone doing critical appraisal
ROB2, GRADE and CASP are supported, and every matrix cell is an extraction bound to a source span.
How Synthesis Lab compares
- Asking a chatbot to write a literature review
- Produces plausible prose with invented references, which is disqualifying in a thesis.
- Building an evidence matrix by hand
- Accurate but slow, and nothing checks that your extraction matches the source.
- Synthesis Lab
- Every cell is a verified extraction you can click back to the sentence it came from.

Synthesis Lab questions
Can AI write my literature review?
It can draft synthesis grounded in papers you have actually collected, with every claim carrying a verified citation. It will not invent sources, and unsupported claims are flagged rather than hidden.
Does it support PRISMA systematic reviews?
Yes. Screening decisions are logged, counts are tracked, and a real PRISMA flow diagram is generated for your methods section.
What about critical appraisal?
ROB2, GRADE and CASP appraisal are supported, and every evidence-matrix cell is an extraction bound to a source span you can inspect.
