Wren
Wren is a free, open-source, local-first reference manager for research on Apple Silicon Macs running macOS 14 or later. It handles more than 40 bibliographic item types and keeps PDFs, EPUBs, HTML snapshots, images, and notes as plain files. Built-in PDF and EPUB readers provide annotations, and highlights can be exported inside a PDF. Its Markdown editor supports mathematics, code highlighting, reference links, anchored comments, and automatic backlinks. Full-text and semantic search can point semantic results to source passages. On-device layout analysis, OCR, and table extraction process PDFs, including scans, offline. Libraries can sync through iCloud Drive, Dropbox, Google Drive, or another folder you already sync, without a Wren account or Wren servers. A Chrome connector captures references, PDFs, and snapshots. Optional bring-your-own-model AI supports several providers and local use. Wren also offers a local REST API, deep links, and bibliographic import and export.
