Why these are free
Each one does a job we think people should not have to pay for, and each one shows a piece of how Signl works. The keyword generator writes the searches; Signl runs them every day. The fit checker scores a list you already have; Signl produces a list that arrives scored.
None of them needs an account, none of them has a usage limit, and neither sends what you type to a server. They run as JavaScript in your browser, which is also why they cost us nothing and will stay free.
If you want the method behind them rather than the tools, start with LinkedIn social listening for B2B sales.
