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.
