Built for evidence work
A focused extraction path—not another chat-with-PDF toy. Define what you need once, then reuse it across your corpus.
Drop one PDF or a full batch. Keep moving while files process.
Set the fields your evidence table needs—population, outcomes, follow-up, and more.
Receive structured Excel plus an Audit Trail sheet: quotes, locations, confidence, flags.
Batch intake
Upload multiple papers and extract against the same question set—ideal for screening follow-ups and living reviews.

Output
Consistent columns for filtering and synthesis—plus a second sheet that keeps every answer accountable.
Results and Audit Trail ship together - verbatim quotes, page locations, confidence scores, and review flags so the table stays defensible.
| Question | Verbatim | Location | Conf. | Flag |
|---|---|---|---|---|
| Mean age | "The mean age of the study population was 64.5 ± 8.2 years at baseline." | Results · Table 1 Page 4 | 98% | Verified |
| Follow-up duration | "Participants were followed for a median of 24 months (IQR 18–30)." | Methods · §2.3 Page 2 | 95% | Verified |
| Sample size | "A total of 412 patients met eligibility and were included." | Abstract Page 1 | 99% | Verified |
| Primary endpoint | "Outcome data not explicitly reported in Table 4." | Results · Table 4 Page 12 | N/A | Not found |
| Intervention | "Active treatment with an SGLT2 inhibitor compared with matched placebo." | Methods · Interventions Page 3 | 81% | Needs review |
| Comparator | "Control participants received matched placebo tablets." | Methods · §2.1 Page 3 | 96% | Verified |
| Adverse events | "Safety events were described narratively without a consistent severity scale." | Results · Safety Page 9 | 74% | Ambiguous |
Every cell can point back to the source language, the page it came from, and a status flag when the paper is silent or ambiguous.
Table 1 summarizes demographic and clinical characteristics. The mean age of the study population was 64.5 ± 8.2 years at baseline. Sixty-two percent of participants were male.

Guides on evidence tables, systematic reviews, and HEOR workflows.
HEOR and HTA teams need structured extraction, traceability, and exports modelers can verify. This article sets out what to look for across your toolchain—and how an AI-assisted builder such as Evidence Table Builder fits: PDFs, configurable extraction fields, source-linked evidence, and Excel outputs you align to your own HTA or modeling templates.
Read article →Evidence pyramid explained for systematic reviews: how study design ranks starting strength, when the pyramid misleads, how it pairs with RoB and GRADE, and how to record design + quality in evidence tables.
Read article →Extraction Templates in Builder let you start faster, reuse proven question sets, autosave custom setups, and keep extraction workflows consistent across projects.
Read article →A tour of the Quality Assessment workspace: AI-assisted, evidence-linked drafts for RoB 2, ROBINS-I, NOS, ROBIS, and CORE, with an integrated PDF viewer, verbatim quotes, a downloadable QA proof PDF, plus the roadmap of appraisal profiles on the way.
Read article →A practical HEOR framework for using AI as the second extractor: where it works, where it fails, and how to keep outputs audit-ready.
Read article →Quality frameworks are methodologically strong, but reviewer hesitation persists. The missing layer is decision support under real workflow pressure.
