Yeah let me waste a shitload of time on possible low-quality shit that might have spyware. Based on the advertisement I'm not convinced. I want PDF tools developed by experts, not monkeys pounding on keyboards or shysters who push stupid gimmicks.
PDF software / readers are reliably the least reliable, most likely to have security issues programs on any given machine. I for one would not run C code blindly copied from ChatGPT carelessly.
In this case I think the actual PDF bits are command line tools written by humans though, and just the web wrapping (some small initial piece of it) is originally from ChatGPT.
