 - **HypoGeniC** - Automated hypothesis generation and testing using large language models to accelerate scientific discovery. Provides three frameworks: HypoGeniC (data-driven hypothesis generation from observational data), HypoRefine (synergistic approach combining literature insights with empirical patterns through an agentic system), and Union methods (mechanistic combination of literature and data-driven hypotheses). Features iterative refinement that improves hypotheses by learning from challenging examples, Redis caching for API cost reduction, and customizable YAML-based prompt templates. Includes command-line tools for generation (hypogenic_generation) and testing (hypogenic_inference). Research applications have demonstrated 14.19% accuracy improvement in AI-content detection and 7.44% in deception detection. Use cases: deception detection in reviews, AI-generated content identification, mental stress detection, exploratory research without existing literature, hypothesis-driven analysis in novel domains, and systematic exploration of competing explanations
 
 ### Scientific Communication & Publishing
+- **pyzotero** - Python client for the Zotero Web API v3. Programmatically manage Zotero reference libraries: retrieve, create, update, and delete items, collections, tags, and attachments. Export citations as BibTeX, CSL-JSON, and formatted bibliography HTML. Supports user and group libraries, local mode for offline access, paginated retrieval with `everything()`, full-text content indexing, saved search management, and file upload/download. Includes a CLI for searching your local Zotero library. Use cases: building research automation pipelines that integrate with Zotero, bulk importing references, exporting bibliographies programmatically, managing large reference collections, syncing library metadata, and enriching bibliographic data.
 - **Citation Management** - Comprehensive citation management for academic research. Search Google Scholar and PubMed for papers, extract accurate metadata from multiple sources (CrossRef, PubMed, arXiv), validate citations, and generate properly formatted BibTeX entries. Features include converting DOIs, PMIDs, or arXiv IDs to BibTeX, cleaning and formatting bibliography files, finding highly cited papers, checking for duplicates, and ensuring consistent citation formatting. Use cases: building bibliographies for manuscripts, verifying citation accuracy, citation deduplication, and maintaining reference databases
 - **Generate Image** - AI-powered image generation and editing for scientific illustrations, schematics, and visualizations using OpenRouter's image generation models. Supports multiple models including google/gemini-3-pro-image-preview (high quality, recommended default) and black-forest-labs/flux.2-pro (fast, high quality). Key features include: text-to-image generation from detailed prompts, image editing capabilities (modify existing images with natural language instructions), automatic base64 encoding/decoding, PNG output with configurable paths, and comprehensive error handling. Requires OpenRouter API key (via .env file or environment variable). Use cases: generating scientific diagrams and illustrations, creating publication-quality figures, editing existing images (changing colors, adding elements, removing backgrounds), producing schematics for papers and presentations, visualizing experimental setups, creating graphical abstracts, and generating conceptual illustrations for scientific communication
 - **LaTeX Posters** - Create professional research posters in LaTeX using beamerposter, tikzposter, or baposter. Support for conference presentations, academic posters, and scientific communication with layout design, color schemes, multi-column formats, figure integration, and poster-specific best practices. Features compliance with conference size requirements (A0, A1, 36×48"), complex multi-column layouts, and integration of figures, tables, equations, and citations. Use cases: conference poster sessions, thesis defenses, symposia presentations, and research group templates
