Slack:企業內部溝通協作平臺是一個將分散的溝通方式聚集到一個地方，郵件、IM、簡訊、類似 Yammer 的工具、企業內網和 Wiki 等，該平臺由Flickr創始人創辦。

除了整合溝通方式外，Slack 還整合了檔案分享系統，公司內所有共享檔案，包括上傳到 Slack 上的，還有儲存在 Google Doc 或者 Dropbox 裡的，通過內建的搜尋工具，都能進行全文檢索。Slack 還整合了 Twitter、Zendesk、Crashlytics 和 Heroku 等服務，將他們的通知提醒、Bug 追蹤等資料融入到公司內的資訊流中。目的只有一個，做一個能解決公司內所有問題的工具。

Relax. Your team’s communication problems? We’ve got that.Slack brings all your communication together in one place.It’s real-time messaging, archiving and search for modern teams.

Modern Messaging

Fast, flexible messaging for Mac, PC, iPhone, iPad & Android. Archived and organized as you go, with configurable alerts, notifications and sync so you never miss a beat.

Any File, Anywhere

Share, serve, star & comment on files. Images, PDFs, text snippets, zips —even files you store elsewhere, like Google Docs— are all indexed & accessible wherever you go.

Universal Search

Slack is built around search from the ground up. It captures everything you put in. Slice, dice, filter, sort and winnow: you’ll find what you need faster.

Slack is just fun to use. We’ve used a lot of tools to engender productivity – agile tools, bug trackers, task managers – and they become all about the tools. Slack gets out of the way and allows us to communicate as if we’re in the same room.
