What it does
PaperTrace is purpose-built for scientific evidence workflows. It retrieves papers, extracts claim-level evidence, compares findings across studies, and generates structured reviews with verifiable citations. Its strength is trust at the evidence layer: every output stays tied to source literature, giving researchers and teams faster synthesis with traceability, accuracy, and auditability.
PaperTrace helps researchers run systematic literature reviews with AI-assisted search, screening, structured extraction, narrative synthesis, and exports.
Type in your research question. PaperTrace searches 250 million+ papers, screens every abstract, and drafts your synthesis in minutes. PaperTrace is AI literature review for researchers who need a traceable workflow from research question to evidence table, synthesis, and export. Use PaperTrace to search PubMed and additional literature sources, screen abstracts, fetch open-access full text, define extraction schemas, synthesize findings, identify research gaps, and export review artifacts. PubMed/MEDLINE is the primary source and works for any topic searchable there. Pro and above unlock multi-source search across Semantic Scholar, Europe PMC, OpenAlex, bioRxiv/medRxiv preprints, and…from papertrace.co

Open Paper2025 · openpaper.ai · ▲289Hi HN! Open Paper allows you to annotate and understand your research papers with an AI copilot. I wanted a paper-reading assistant that let met actually dig into papers in-place while benefiting from AI tooling. When it comes to studying, I'm not a fan of the typical chat interfaces that obfuscate uploaded files and turn them into black box 'content'. Hence, I've implemented a split-pane view. To mitigate the risk of hallucinations, all AI responses come with grounded citations that refer back to the source material in-flow. Some feature highlights: - Actually read your papers in one place…

Parallel agents, diff reviewer, and multi-model comparisons

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
