Fuentas 1.0 · in beta
Keep your research connected to its sources.
A quieter place for the papers, notes, and citations that shape your work.
Made for Mac, iPhone, and iPad. We’re inviting testers to help shape Fuentas 1.0.
Research has a shape
From the first question to the final reference list.
Fuentas brings the small, connected parts of research into one native workspace: a source, a thought in the margin, a thread between papers, and the citation you need at the end.
A thoughtful workspace
See how it worksGather with care.
Look up a source by DOI, URL, arXiv, PubMed, ISBN, or title. Bring in PDFs and citation files, then review what will be added before it reaches your library.
Adding referencesGive ideas room to connect.
Arrange references in nested collections for a project or chapter. Keep one source in several places, and add your own notes without losing the page they came from.

Stay close to the page.
Read a PDF beside its reference. Search within it, mark a passage, leave a page note, and return to that exact spot when you pick up the work again.
Reading and annotationConnect this to the opening chapter.
Make it yours
Your research, on your terms.
Choose a local library or optional iCloud sync. Decide when an AI provider can see selected research. Keep a separate backup in a place you choose.
