Metaso
Metaso (秘塔AI搜索) is an AI search engine built for research-grade answers rather than link lists. It searches the open web, document libraries, and academic indexes such as PubMed, SCIE, EI, and JCR, then writes a structured, cited answer. Extra modes produce mind maps, slides, interactive web pages, and deep-research reports, and a paid Search API exposes the same index to developers.
Trooly
Trooly is an AI-native qualitative research platform. It writes the research plan, screens and recruits participants, moderates one-on-one multimodal voice interviews, and synthesizes transcripts into themed reports. Product and research teams can bring their own users at $10 per interview, or let Trooly recruit from a network of 180M+ respondents, with every interview quality-checked before delivery.
