Sorry for slack reply Nikolas C., busy time!
There are broadly 2 types of tool:
(1) custom internal tools to help with content creation (feed it examples of a writing style you like , tools to scrape the web & find relevant or trendy content to inspire you) - lots of workflows via n8m and make.com
(2) free mini tools as an acquisition method (way more effective from personal experience). as cost to code is lowering w/ AI you can build these out pretty easily instead of offering boring lead magnets or just sending traffic to a purchase/book a call page. Increases lead capture dramatically - great examples of things like Jolie Water Report or Hubspot’s Website Grader. has higher perceived value than lead magnet for ads and have built out more than a dozen in the last year because they’re working so well for us.
