Search and filters take some learning, and the paid apps go through a demo. - **Platforms and integrations: B.** Web, with ReadCube, ORCID and ChatGPT.

That is not a weekend's work, with an AI app builder or without one. It is one of the better ones too: its GPA of 2.8 is higher than 41 of the 49 other AI research tools we grade. - You could not: A library of papers and sources to search. - You could not: A search engine with an AI model behind it. - You could not: Citation records for millions of papers. - You could not: It plugs into other products, ReadCube, ORCID and ChatGPT among them, and has an API.
