Virtual Scientists leverages GPT-based language models to create specialized AI Agents that replicate expert scientists across various fields. Each virtual researcher is configured with tailored prompt engineering to provide accurate, context-aware answers, propose experimental protocols, interpret scientific data, and generate insights. Users select a scientific persona, input their questions or project details, and receive detailed, discipline-specific guidance supported by references and reasoning for educational or research purposes. The platform is hosted on GitHub Pages and is fully open-source. The codebase supports easy customization and extension of new scientific personas by modifying JSON configuration files. Ideal for collaborative research, teaching demonstrations, or personal study, Virtual Scientists bridges the gap between AI language models and practical scientific problem-solving by offering a dynamic, interactive environment for exploring complex topics with expert-like guidance.

Resea AI is an autonomous AI research assistant that independently conducts multi-round deep research by integrating web search and academic libraries such as Google Scholar, PubMed, and arXiv. It generates detailed, well-cited reports for academic, business, and other research purposes. Users submit assignment requirements, and Resea AI independently thinks, researches, writes, and revises, providing unlimited word count and citation format support.
