MathPile is a mathematics-centric corpus containing approximately 9.5 billion tokens. It draws mathematical content from textbooks (including lecture notes), arXiv, Wikipedia, ProofWiki, StackExchange, and web pages. It is suitable for K-12, university, graduate-level, and math competition applications. MathPile boasts high data quality and comprehensive data documentation to enhance transparency and provide users with flexible data utilization capabilities. MathPile adheres to the BY-NC-SA 4.0 license and plans to release a commercially available version soon.

DocGraphLM is a document graph language model for information extraction and question answering. It employs advanced vision-rich document understanding techniques, combining pre-trained language models and graph semantics. Its uniqueness lies in proposing a joint encoder architecture to represent documents and a novel link prediction method to reconstruct the document graph. DocGraphLM predicts the direction and distance between nodes through a convergent joint loss function, prioritizing neighborhood restoration and minimizing the weight of remote node detection. Experiments on three SotA datasets demonstrate that incorporating graph features consistently improves performance in information extraction and question-answering tasks. Furthermore, we report that employing graph features accelerates convergence during training, despite these features being constructed solely through link prediction.

QAnything is a local knowledge question-and-answer system that supports any file format and database. It can easily import various format files stored locally and provides accurate, fast, and reliable answers. Currently supported formats include: PDF, Word (doc/docx), PPT, Markdown, Eml, TXT, images (jpg, png, etc.), webpage links, and more formats will be added in the future. QAnything has data security, supports offline installation and usage; supports cross-language questioning in Chinese and English; supports massive data questioning, solving the problem of data retrieval degradation for large-scale data; it is a high-performance production-grade system that can be directly used in enterprise applications; one-click installation and deployment, user-friendly experience out of the box; supports multi-knowledge base questioning and other functions.

Recall is an AI-driven knowledge base that can summarize and save any online content. It can summarize YouTube videos, articles, podcasts, PDFs, recipes, movie and TV show lists, and other web page content and automatically categorize and save the summaries to your personal knowledge base. Saved summaries will also automatically be linked to related content you've saved in the past, helping you find connections as you consume content and rediscovering past content when relevant topics arise. Recall also utilizes scientifically-backed techniques like spaced repetition and active recall to help you review and solidify the knowledge stored in your knowledge base.

Telescope is an AI-powered knowledge base and natural language search tool. It can transcribe videos, generate document summaries and extract web pages, and enables fast knowledge discovery through natural language search. With Telescope, you can unlock knowledge 10 times faster than traditional search.
