Congratulations for launching something.
Here is some feedback after a quick visit to the website's home and pricing pages. I'm criticizing some parts, not to discourage you, just to highlight some friction encountered with the marketing message.
The toolset likely has some powerful features, useful to some users. However, the text of the home page does not _show_ clearly what it does, why it is valuable, and who might need it.
The first section (above the fold) currently lists some features. Instead, it should rather tell which problem is solved, and for whom.
Some of the features are not clear to me, and I guess to other people too.
Here is my reaction to some of them:
* "Search more than 1,200 websites using their own search" --> why should I care? website's search engines are often not so good (reddit, stackOverflow...)
* "Create custom popup menus and context menus" --> popup? the annoying windows interrupting my workflow? no thanks!
* "Use the command line with aliases" --> is this a terminal app in addition to browser extension?
N.B.: I did not play the videos embedded in the website, I recognize that these might address the questions raised about the product.
Good luck, and keep up the good work :)
