In their own words
Ambercite
Ambercite is a web and API platform for finding patents related to one or more starting patents. Ambercite Ai uses deep-learning and network algorithms to score and rank similar patents from a database described as containing over 106 million patents and 175 million citations. AmberScope maps and clusters similar or important patents that cite one another. The listed applications include prior-art searching, licensing, instant patent landscaping and portfolio benchmarking. Users can run it alongside existing patent-search databases or as a standalone tool. An API is available to patent offices and non-competing industry players. The maker identifies corporations, patent examination offices, IP firms, analysts and searchers as users. AmberScope is also aimed at R&D teams and business owners who are unfamiliar with Boolean parameters or technical class codes. A 21-day trial provides both products without a card or payment and allows 20 searches. Trial searches accept up to three patents, show up to 25 results, obscure five more randomly, and cannot be exported to Excel. Paid subscriptions are annual, with pricing based on organization details.
PQAI
PQAI is an AI-powered patent search platform intended to help find prior art relevant to an invention. Searchers can describe an idea in natural language without special formatting or technical expertise. Its tools include semantic search, CPC Classification Prediction, Technical Concept Extraction, Patent Data Retrieval, and claim analysis. The Free plan searches across 100M+ patents and returns 20 results per query at standard speed. PQAI+ offers 500 results per query, faster search, full-text excerpts, and export. The service is available on the web and through an API, and PQAI describes it as open source. API plans include MCP server access and compatibility with Claude, ChatGPT, and Gemini. PQAI also provides an iFrame embed with instructions for WordPress, Wix, and custom-built websites. The company says it erases each query from its servers after generating results. API requests use token-based authentication and HTTPS, alongside rate limiting and access controls. PQAI identifies individual inventors, law firms, patent examiners, enterprises, and R&D teams as users. Paid plans start at $20 a month; commercial integration into another product requires a commercial API or Enterprise plan.
