Hi Product Hunt 👋

Most citation mistakes don't happen when you write the reference list. They happen weeks earlier, when you copy a quote without its page number or save the same paper twice.

Plagx Research Kit is a free notebook that fixes this at the source:

📒 Keep a simple source log (one row per source, quote + page number)

📚 Turn it into an APA 7 or MLA 9 reference list and in-text citations

🔍 Catch duplicate sources and missing details before you submit

✍️ Find citations in your draft that never made it into your reference list

📥 Download templates: source log, literature matrix, annotated bibliography, research plan

It runs in Google Colab: open it, click Run all, no install or sign-up beyond a Google account. Everything is open source (MIT), and citations use our plagx-cite package on PyPI.

What it doesn't do: it doesn't check for plagiarism or detect AI-generated text. By Plagiarism Checker X - for full plagiarism checks and AI-generated text detection, visit the Text Similarity Detector:

Would love feedback on which citation styles or templates to add next!
