1. Yac

All these tools above are great but just don't meet remote work standards. We're not saying Yac is perfect but we designed it with a remote-first mindset. With Yac, collaborating on a project even if your team is offline is now possible. At Yac we believe communication is a key component to a team's success and can be done without constantly spinning up a meetings or scheduling times to talk. We've built a tool to help you on-board your team with 1-Click, share voice messages directly to Slack, and truly collaborate on your own terms. Remote work is meant to liberate, and we think It's time to speak without the burden of a meeting.

Pros:

• Easily talk to your own teammates by leaving them a message about a project or quickly asking them for an update.
• No more trying to sync up schedules or setting meetings.
• On-board your time with 1-Click and share voice messages directly to Slack.
• Asynchronous voice messages mean you listen on your own time.
  

Cons

• Voice-only
