Quill, a team messaging service, is joining Twitter.
Quill’s service will allow data to be exported until December 11 with all data deleted after that.
Customers will receive full refunds for active accounts.

Active teams will receive a full refund, Quill’s announcement says.

Quill, a team messaging service, has announced that it is joining Twitter. The move will see Quill close down for good, with services being turned off and data deleted on Saturday, December 11. That means that teams have just days to export their data and messages before it’s too late.

We started Quill with the goal of increasing the quality of human communication. We believe the tools we use to communicate today are not the best they can be. Together with Twitter, we will continue to pursue our original goal — to make online communication more thoughtful, and more effective, for everyone.

The announcement was made today with Quill stopping short of saying what we should expect it to be used for once under Twitter’s wing.

Quill will be shutting down, but its spirit and ideas will continue on. You’ll be able to export your team message history until 1pm PST, Saturday, December 11th 2021, when we will be turning off our servers and deleting all data. For all active teams, we’re issuing full refunds.

It’s possible that Twitter could use Quill to bolster its own messaging systems, specifically DMs, although that’s little more than guesswork at this point. Twitter may simply want to use Quill internally, rather than turn it into a client-facing feature.

Quill was a company that included “engineers and designers who previously built products at Apple, Square, Stripe, Snap, Wish, Facebook, and OpenAI,” the company’s ‘About’ page says. One of the former Apple employees worked on iMessage and FaceTime, among other services.
