Academic Paper Search
Search across six academic databases simultaneously with filtering, deduplication, and direct PDF access.
Omnilib searches six academic databases in parallel and merges results into a single deduplicated list. Search from within the Deep Research Hub or trigger a search directly from an AI agent conversation.
Sources
| Source | Specialty |
|---|---|
| arXiv | Preprints in physics, mathematics, CS, quantitative biology, economics |
| Semantic Scholar | Citation graphs, abstracts, paper influence scores |
| PubMed | Biomedical and life science peer-reviewed literature |
| OpenAlex | Open metadata for journals, authors, and institutions across disciplines |
| CrossRef | DOI registry with metadata for publications from all fields |
| DBLP | Computer science journals, conferences, and workshop papers |
All six sources are queried for every search. Results from different sources that refer to the same paper are merged into a single entry.
Searching for papers
From the Deep Research Hub
The Deep Research Hub runs paper searches automatically as part of its pipeline. You do not need to configure individual queries — the research agent handles this based on your research plan.
From the AI agent
Ask the AI agent to search for papers directly in any conversation:
"Find papers on diffusion models for protein structure prediction."
The agent uses the paper_search tool and returns results inline in the chat. You can then ask it to add specific papers to your bibliography or open them in the viewer.
Manual search
Open the paper search panel from the sidebar:
- Type your query in the search field.
- Apply any filters (see below).
- Press Enter or click Search.
Results appear in the panel below the search bar.
Filters
Narrow results using the filter bar:
| Filter | Options |
|---|---|
| Date range | Set start and end year |
| Venue | Filter by journal or conference name |
| Citation count | Minimum citation threshold |
| Source | Show results from specific databases only |
Filters apply across all sources simultaneously.
Result cards
Each result shows:
- Title — Linked to the paper's canonical page
- Authors — Listed with links to author profiles where available
- Year — Publication year
- Abstract — First 3–4 sentences, expandable
- Citation count — From Semantic Scholar where available
- Source badges — Which databases returned this paper
Working with results
Add to bibliography
Click Add to Bibliography on any result card to import the paper's metadata as a BibTeX entry. The reference becomes available in your bibliography panel and in LaTeX \cite{} autocomplete.
Download PDF
Click Download PDF on a result card to save the paper. If the paper is open access, the PDF downloads directly. For paywalled papers, the button links to the paper's DOI page.
Open in viewer
Click Open to load the paper in the PDF Viewer. The viewer provides annotation tools and OCR text extraction.
Deduplication
When the same paper appears in multiple sources, Omnilib merges the entries using DOI matching and title normalization. The merged entry combines metadata from all sources — for example, citation counts from Semantic Scholar are added to a record found via CrossRef.
