Synthesized answer

Evidence moderately supports improved insulin sensitivity with time-restricted eating[1][2], though benefits appear equivalent to daily calorie restriction[3][4].

Sect. 02 · Capabilities

Grounded in the literature. Always.

Every answer traces back to real, peer-reviewed sources. No hallucinations, no fabricated citations, no “according to some studies” hand-waving.

Semantic Scholar — 200M+ papers

Every query pulls fresh results from the Semantic Scholar graph, then vector-ranks them against your exact question.

Consensus meter on every query

See at a glance how many papers support, contradict, or remain neutral on your hypothesis. No more cherry-picking.

Grounded synthesis with citations

Claude reads the top-ranked abstracts and writes a single evidence-based answer with inline [1][2][3] citations you can verify.

Filter by study type

Narrow to RCTs, meta-analyses, cohort studies or systematic reviews. Filter by year and minimum citation count.

Saved search history

Every query and answer you run is saved. Re-run, share, or export them to Zotero when you're ready to write.

Paper-level deep dives

Click any citation to read the abstract, authors, journal, year and citation count — plus related papers ranked by similarity.

Sect. 03 · Method

From question to cited answer in seconds.

A three-step pipeline. Transparent at every layer — you can always click through to the original paper.

01

Ask a real research question

Type in plain English: "Does intermittent fasting improve insulin sensitivity in adults with prediabetes?"

02

Papersearch pulls & ranks the literature

We fetch fresh results from Semantic Scholar, embed abstracts with Voyage AI, and rank the top matches by semantic similarity.

03

Get a cited answer + consensus meter

Claude synthesizes an evidence-based answer with inline citations. A visual meter shows how the literature breaks down: Supports / Neutral / Contradicts.

Sect. 04 · Dispatches

From the labs, clinics and committee rooms.

We cut our literature review time from 3 weeks to 4 hours. Papersearch surfaced 12 RCTs we'd missed on PubMed — the consensus meter alone changed how I read evidence.

Postdoctoral Researcher, Stanford Medicine
As an ICU physician, I don't have time to read 40 papers per clinical question. Papersearch gives me the grounded summary with citations. It's now part of my morning round prep.
Dr. Marcus Hale
Attending Physician, Johns Hopkins ICU
I brief the Senate Health Committee weekly. Papersearch lets me cite 8 peer-reviewed sources for every claim — with the Supports/Contradicts breakdown my chief of staff insists on.

Sect. 06 · Corrigenda

Questions from the peer review.

Every search queries the Semantic Scholar Graph API — the largest open scientific corpus (200M+ papers with abstracts). Matched papers are embedded with Voyage AI and cached in our index, so subsequent searches surface them instantly via pgvector similarity.
