Your personal research assistant
Watson is the easiest way to collect, organise, annotate, cite and share the sources behind your work. Capture a reference from any web page with a single click, read and annotate PDFs, and generate citations in thousands of styles.
A full web library — collect, organise, cite and share your research from any browser.
Everything your research needs
Seven capabilities, one coherent workflow — from first discovery to finished bibliography.
Collect
Save references and full-text PDFs from any website with one click, or add items by DOI, ISBN, PMID and arXiv ID.
Organise
Sort your library into nested collections, colour-coded tags and saved searches. Find duplicates and merge them cleanly.
Read & Annotate
A built-in reader for PDF, EPUB and web snapshots. Highlight, underline, draw and comment — every annotation is first-class, syncable data.
Cite
Cite as you write in Word, LibreOffice and Google Docs, with more than ten thousand citation styles to choose from.
Sync
Your library stays in step across every device, online and offline. Data sync is always free and unlimited.
Collaborate
Create group libraries to share references with a class, a lab or the whole world, with fine-grained permissions.
Extend
A public API, a streaming service and a plugin framework let you build on top of your library however you like.
