RubberDucky

RubberDucky — persistent reading assistant for papers with compounding memory.

RubberDucky is a reading companion built for research papers—not a generic chatbot. Select text or figures on any page, get AI explanations grounded in what you have already read, and build a notebook that compounds across sessions and projects. HOW IT WORKS • Select text on arXiv, publisher sites, or PDF HTML views and click Explain. • Notes and highlights stay organized by source page and project in the side panel. • Ask questions across your accumulated notes or generate a quick review quiz. • Optional voice tutor: click the teacher icon for spoken Q&A about your current selection (user-initiated only). KEY FEATURES • Persistent reading memory — explanations reference prior notes in the same article and across your project. • Side panel notebook — switch between Notes and Annotations without leaving the page. • Google sign-in — sync notes to your account across devices (optional). • Google Docs export — compile and export notes when you connect Docs (optional). • Voice tutor — microphone used only when you start a voice session.
