Does anyone know a really solid way to keep track of a history links? Ideally I can input both URLs and media and it would be well organized (categories or tags?), easy to search (powerful search function).

Like a lot of you, I am sure, I use Slack for communication with my team. Of course, each of Slack channel is set up around "categories" of the business (e.g, marketing, design ... whatever) and naturally, we all put links and media into each that we always need to reference later. The problem is Slack doesn't keep all your history unless you pay a per user fee, which adds up very quickly.

Thanks!
