The verdict: can you vibe code Scholarcy?
Build a personal subset for your own reading workflow, but keep paying if you rely on the polished browser extensions and Zotero sync.
Building the core loop—uploading a PDF, extracting text, passing it through an LLM with structured JSON output, and rendering it into a flashcard UI—is a straightforward weekend build with modern AI tools. However, academic PDFs are notoriously brutal to parse cleanly (two-column layouts, footnotes, formulas). Furthermore, writing and maintaining cross-browser extensions that inject sidebars securely without breaking on CORS policies or paywalled repositories involves tedious, unglamorous debugging.
Estimated effort: 2-3 weeks part-time

The hard parts of vibe coding Scholarcy
- Accurate academic PDF parsing (handling two-column layouts, tables, and mathematical notations cleanly without garbling text)
- Constrained structured information extraction from LLMs to guarantee consistent flashcard schema fields
- Bi-directional reference syncing and citation formatting (APA/MLA/Harvard)
- Building and maintaining cross-browser extensions (Chrome, Firefox, Safari) that inject sidebar UI reliably

Build guide
01Project Scaffolding & Database Schema
Initialize a Next.js project with Tailwind CSS, configure better-auth, and set up the SQLite database schema using Drizzle ORM to store summaries, flashcards, tags, and user metadata.
Create a new Next.js project using TypeScript and Tailwind CSS. Integrate better-auth for email/password authentication with a local SQLite database using Drizzle ORM. Define database schemas for 'documents' (id, userId, title, rawText, createdAt), 'flashcards' (id, documentId, synopsis, highlightsJson, background, conclusion, limitations), and 'collections' (id, userId, name). Ensure database connection configuration supports Cloudflare D1 or local SQLite file for development. Include basic layout navigation with shadcn/ui primitives.02PDF Ingestion and Text Extraction Pipeline
Implement a robust file upload endpoint that accepts research PDFs, extracts clean text using a robust parsing library, and handles multi-page document streams.
Implement a server-side API route in Next.js that handles multipart form data for uploading PDF documents (up to 50MB). Use a reliable text extraction library (such as 'pdf-parse' or 'unpdf') to extract raw text from all pages. Handle edge cases like multi-column layout artifacts, missing whitespace, and scanned image-only PDFs by returning a clear error message if text density is too low. Store the extracted text temporarily or link it directly to a newly created document record in the database.03AI Flashcard Summarization Engine
Integrate the Vercel AI SDK with Anthropic Claude to process extracted research text and generate structured flashcard JSON containing synopses, highlights, and limitations.
Build an AI summarization service using the Vercel AI SDK and Anthropic Claude Sonnet. Write a robust prompt instructing the model to parse the extracted research paper text and return a strictly typed JSON object matching our flashcard schema: synopsis (narrative overview), highlights (array of key findings), background (context and prior work), methodology, results, conclusion, and study limitations. Use structured output validation (zod) to ensure malformed JSON from the LLM triggers automatic retries or graceful fallback handling.04Library & Flashcard Dashboard UI
Build the personal library interface allowing users to search, filter by tags, organize into collections, and view interactive flashcard summaries.
Create the main library dashboard in Next.js. Display saved flashcard summaries in a responsive grid and list view with search filtering by title, keyword, and collection tags. Build a dedicated Flashcard viewer page that presents the structured data in clean, digestible tabs or sections: Synopsis, Highlights, Methodology, Key Findings, Limitations, and Citations. Include inline editing so users can update notes or highlight key text directly within their flashcard view.05Literature Matrix & Bibliography Export
Add export utilities to synthesize multiple flashcards into Excel matrices and generate formatted bibliographies.
Implement export functionality allowing users to select up to 100 flashcards from their library and export them as a structured Excel spreadsheet (.xlsx using 'xlsx' library) forming a Literature Synthesis Matrix comparing key findings, participants, and results across papers. Additionally, implement a one-click formatted bibliography generator that compiles citations into standard APA/MLA formats for copying or download.06Browser Extension Scraper Shell
Build a lightweight Manifest V3 browser extension that allows capturing open-access articles and sending them to the personal library backend.
Build a Manifest V3 browser extension (Chrome/Firefox compatible) featuring a popup UI and content script. The extension should extract the current page's URL and visible main article text, or detect open-access PDF links. Add a 'Summarize with Scholarcy' button that sends the content securely to your hosted Next.js API endpoint, receives the generated flashcard preview in a sidebar iframe, and provides a 'Save to Library' action authenticated via stored API tokens.
