What do people recommend as an instant chat platform (equivalent to #Slack, #Discord, i.e. with threads and public vs private channels, possibility to post photos and documents, something that you'd use at work to keep track of complex discussions & decisions) that doesn't have nor plan to add any #genAI "training" or "functionalities"?
I thought #Mattermost might be good but it turns out they also have genAI stuff.. (https://mattermost.com/pricing/)
