Our app is a Twitch Extension for streamers so we're intending to use discord as that's the tool as it's commonly used in the community.
Haven't decided whether we'll use a bot for tickets but we'll explore it.
Right now we use Crisp for live chat and have been loving it. We pay much less than we did when we used intercom and so far it's been amazing. We do YouTube and Loom videos for commonly asked questions to send to our customers as well.
@kit_fach awesome, loom videos for FAQs can be really helpful. Tolstoy also provides this functionality, we just launched on PH today, would love to know if you think this could also be a solve for you!
