A Syften alternative that also watches LinkedIn.
Syften is fast and covers many communities. Overhear is for when LinkedIn matters, when you'd rather not pay add-ons for X and YouTube, or when you only scan a few keywords and a monthly plan sits mostly idle.

Is there a free trial?
Every new workspace gets 1,000 credits once, with no card. After that you buy prepaid credits from $10, and they never expire.
