That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 54 of the 69 other AI research tools grade higher. It costs $239.40 a year. - You could make: Reports: an app builder makes this well. - You could not: A library of papers and sources to search. - You could not: Several people working in it at the same moment. - You could not: AI features, unless you pay a model provider for each request yourself.
