A year ago, a post on HN about a personal assistant to find restaurants in San Francisco by chatting with it attracted a lot of attention: https://news.ycombinator.com/item?id=10060074

The domain getmyra.co now redirects to http://www.myralabs.com/ about an API to "power Slack and Messenger bots, customer service applications, and others that require sophisticated natural language understanding."
Do you know why the service was shut down ? Was it replaced by or integrated into something else ? What did the promising technology become ?
