Sounds to me like a Slack bot (or whatever they use) that prompts you to provide an update to a couple of questions, like a text-based 'stand-up', at a scheduled time or manually triggered.

But I may just be overfitting to my own experience with something like that (not at Shopify) and don't know why that couldn't just be Jira (or whatever) comments. To have a more product-oriented than ticket-micro-managing view perhaps?

It's nothing too fancy. A Rails app with some text boxes and nice styling.
