Slack:企业内部沟通协作平台是一个将分散的沟通方式聚集到一个地方，邮件、IM、短信、类似 Yammer 的工具、企业内网和 Wiki 等，该平台由Flickr创始人创办。

除了整合沟通方式外，Slack 还整合了文件分享系统，公司内所有共享文件，包括上传到 Slack 上的，还有储存在 Google Doc 或者 Dropbox 里的，通过内置的搜索工具，都能进行全文检索。Slack 还整合了 Twitter、Zendesk、Crashlytics 和 Heroku 等服务，将他们的通知提醒、Bug 追踪等数据融入到公司内的信息流中。目的只有一个，做一个能解决公司内所有问题的工具。

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.
