Tatsu
What Tatsu is
Tatsu is a productivity application suite built natively into Slack. It gives users dashboards for personal and team workload, lets Slack channels serve as project homes, and turns colleagues’ messages into personal follow-ups. Teams can schedule polls and syncups, send messages, assign tasks, review workloads, and use templates for repetitive work. Tatsu also supports asynchronous discussions inside Slack as an alternative to some synchronous meetings, with dashboards and reporting, workflow automation, and portfolio management listed among its capabilities. The service has a free plan, a 14-day trial, and paid pricing from $2.50/mo (annual). The Everyone (Annual) plan is listed at $2.50 a year, billed $2.50 /participant/mo/yr; the Privileged (Annual) plan is $3 a year, billed $3.00 /participant/mo/yr. Enterprise pricing is available by sales chat. Participants are Slack users who create or interact with Tatsu items and are counted each billing period. Tatsu depends on continued Slack access.
