Leo from ChatGrape here. We're focusing on two areas of innovation, to add a certain level of intelligence to chat based team communication:
1. Deep Service Integrations: Our integrations of tools and services like Gmail, GitHub etc function on a much more integrated level than what has previously been achieved. For instance, on ChatGrape, all your issues (GitHub) and files (Google Drive / DropBox) are available within the chat, thanks to a smart auto complete that attaches or references all your documents - right as you type.
2. Speech Act Detection (Natural Language Processing): This is all about the triggering of workflows based on normal, "day to day" communications. For example, if I were to write, "Hey Tobi, let's meet up tomorrow at 2pm to discuss the front end issue!" three things will happen: First, you'll be notified, second a calendar event will be added to your Google Calendar and third, the topic or issue will be automatically referenced or attached.
Natural language processing within ChatGrape goes much further, anyhow, and is a topic where our engineering team has gained many years of experience with previous projects.
We're using to make communication simpler and more efficient, whilst not disrupting your normal flow of conversation. (Another example of this is to automatically detect and mark whether / or questions, and mark them as such.)
ChatGrape went live in an Early Access Phase (Pre-Beta) phase about six weeks ago and not nearly everything of what'll ultimately make ChatGrape the first smart communication solution for teams is fully operational or even deployed yet.
However, what I wrote above will give you guys a better idea of it is that sets ChatGrape apart from all existing solutions like Slack or Hipchat.
I'm looking forward to your feedback and questions and I'm always available via lf@ubergrape.com! And we'd of course be happy about you guys joining our Early Access Phase to provide further feedback.
