How to vibe codePaperpile
The no-fuss reference manager for the web

The verdict: can you vibe code Paperpile?
You can build a personal reference manager with a web UI and PDF parser, but the real-time Google Docs collaborative add-on ecosystem is a grueling engineering bottleneck.
Replicating Paperpile's core personal workflow—saving references, organizing tags, reading and annotating PDFs, and generating a BibTeX or markdown bibliography—is entirely feasible with AI coding agents. However, Paperpile's true moat lies in its deep, bi-directional Google Docs sidebar integration that handles live footnotes, collaborative citation injection, and multi-author bibliography sorting without breaking. Furthermore, writing robust DOM scrapers that harvest metadata cleanly across thousands of eccentric academic publisher paywalls requires constant maintenance. For personal use, building a standalone web library with an integrated PDF viewer and local export is a rewarding 3-4 week project, but trying to clone the Google Docs plugin ecosystem will test your patience against strict third-party extension review pipelines and web-socket sync edge cases.
Estimated effort: 3-4 weeks part-time
What you can't replicate
- The seamless, native Google Docs real-time collaborative citation sidebar used by co-authors
- Instant one-click metadata extraction across thousands of publisher paywall domains without maintenance overhead

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js application, configure Turso database connectivity, and implement better-auth for single-user secure login.
Scaffold a new Next.js 16 application using Tailwind CSS and TypeScript. Set up Turso (libSQL) as the database client and configure better-auth with Google OAuth authentication. Create database tables for 'references' (storing DOI, title, authors, year, journal, abstract, reference_type), 'folders' (for library organization), and 'pdf_annotations' (storing page number, coordinates, highlight color, and comment text). Ensure all relational foreign keys and indices are optimized for fast searching.02Reference Import & Metadata Ingestion Engine
Build backend endpoints to parse DOIs, PubMed IDs, and uploaded BibTeX files to populate structured reference entries.
Build a metadata ingestion service in the Next.js backend. Implement API integrations with Crossref and PubMed APIs to fetch complete bibliographic records given a DOI or PMID. Create a BibTeX file parser utility that ingests uploaded .bib files, parses entries into structured JSON objects, and saves them to the Turso database. Include a duplicate detection algorithm based on normalized titles and DOIs.03PDF Storage & Cloudflare R2 Integration
Implement drag-and-drop PDF uploads linked directly to reference items, stored securely in Cloudflare R2 object storage.
Implement file upload handling in Next.js connected to Cloudflare R2 object storage. Allow users to attach PDF files and supplementary documents (Excel, Word) to existing reference records. Create secure pre-signed URL generation endpoints for viewing and downloading files. Ensure automatic filename normalization based on author, year, and title metadata patterns.04Web-Based PDF Reader & Annotation Canvas
Integrate PDF.js to render research papers directly in the web app with interactive text highlighting and sticky notes.
Build a web-based PDF reader view using PDF.js embedded in a Next.js component. Implement interactive text selection and highlighting in multiple colors, along with sticky note attachments tied to specific coordinate rects on PDF pages. Save all annotation layers back to the Turso database linked to the reference ID and sync positions accurately on zoom and page turn.05Citation Formatting & Bibliography Generation
Integrate citation formatting engines to generate clean bibliographies and in-text citations across standard formats like APA, MLA, and Chicago.
Integrate the Citation Style Language (CSL) formatting processor (or citeproc-js wrapper) into the application. Build a citation picker modal that allows users to search their library, select one or multiple references, specify page numbers or chapters, and copy formatted in-text citations or full bibliographies in APA, MLA, Chicago, or BibTeX formats.06Library UI & Organization Dashboard
Construct a responsive dashboard featuring folder trees, colored labels, star ratings, and real-time search filters.
Design and build the main library dashboard using Tailwind CSS and shadcn/ui components. Implement a sidebar with custom folders, tag filters, and star ratings. Build a lightning-fast search bar that filters references across title, authors, journal, and abstract in real-time. Add bulk actions for moving references into folders, exporting selections, and deleting items.
