AI Search & Research Tools

PRODUCT OVERVIEW
Metaso is an AI search product built around ad-free, direct-to-result searching. Users can search the whole web, document libraries, or academic sources, narrowing academic results by Chinese and English databases, PubMed, core-journal and CAS/JCR quartile filters, and SCIE or EI indexing. Beyond search, it offers deep research that plans a framework before gathering and integrating material, file upload for document-based Q&A, page-range explanation of uploaded material, topic collections, a bookshelf, and custom skills. It also includes slide creation, interactive web pages, podcast and video generation, and an API. A companion voice feature advertises 0.5-second speech transcription and organization. It suits students, researchers, and knowledge workers who need sourced answers and research synthesis.
Choose a search scope such as the whole web, document library, or academic sources, then enter your query to get direct results.
In academic scope, filter by Chinese or English databases, PubMed, core-journal lists, CAS or JCR quartiles, and SCIE or EI indexing.
