Would you pay for tool access like this?

I'm a coder, and i do SEO among other thing too.

I'm making a tool that goes and make keywords list of Products name. You give it a brand or something of a sort and it builds you a list of products regarding that brand.

This is for highly targeted key phrases i guess. Trying to avoid the flock of sheep that competes for same keywords.

Let me know if this would be of interest to anyone to pay low monthly fee, for this tool and others. Message me if you want or just type here what you think.

By no mean this tool is ready for leasing, it's working but not made to be leased. If their is a demand i would consider making it available to the public.

Something that would be good to add to such a tool, would be to help in split testing campaigns making the whole process automated. For example on adwords there are tools that will help you generate campaigns but not ones that can create a variety of campaigns for you and split test them over a large list of keywords. The tool your creating how will it be able to relate one product name to another ? How accurate would something like this end up actually being?

Sounds cool, but how does this tool acquire these keywords, does it snoops around completion websites or checks what kind of advertising keywords are used for this product. Or is it more complicated?

I have a few source i generate these keywords from. I mean this makes really targeted keywords for products specific.

example if you want "DKNY jeans" it would get you stuff like:
dkny jeans live 89 hoodie
dkny jeans drenched eagle slub jersey shirt
dkny jeans printed short-sleeved babydoll jersey top
dkny jeans short-sleeved printed charmeuse top
dkny jeans soho stretch boot cut jeans, orchard blast wash
dkny jeans avenue b straight leg jeans, rinse wash
dkny jeans military relaxed shirt

So you see it's really targeted.

i think google suggest already does the same thing? cmiiw.
