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: 39 of the 89 other AI app builders grade higher. It costs $348 a year. - You could not: A builder that other people can use without writing code. - You could not: A tool that builds and hosts other apps. - You could not: Connections to other products, each kept working as those products change. - You could not: Databases with views, filters and links between them.
