If your team already talks in Slack, the simplest way to stop tasks getting lost is to assign them where the conversation happens. Most task tools have a Slack app now, but they work in two different ways. Slack-first apps run the task list inside Slack itself. Project management tools with a Slack integration let you create tasks and get notifications in Slack, but the work lives in their own app, and each person needs an account there.
1. Workast
Workast is a task and project management app built for Slack, and the best fit if you want tasks assigned, tracked and reminded without leaving Slack.
Create, assign and date a task in one line: /todo Send client invitations Monday 9am @Blake
Turn any Slack message into a task from its More actions menu
See a channel's open tasks with /todo list, and share them with the channel
Each person gets a daily list of due and overdue tasks, plus a reminder before each due time (30 minutes by default)
Tasks can repeat daily, weekdays, weekly, monthly or yearly
/mytodo keeps private tasks; /checklist posts a shared checklist
Each Slack channel can have its own project space with lists for each stage
Custom forms submitted from Slack create tasks automatically
AI workflows handle assignment, routing and follow-ups
Everyone in your Slack workspace gets access when Workast is installed, with no invites, separate passwords or accounts. The Essential plan is free for unlimited users and runs inside Slack. Standard ($39 per month for 8 users, billed annually; $47 monthly) adds the web app with list, board and calendar views, custom forms, saved reports delivered to Slack on a schedule, subtasks, templates, time tracking and AI workflows. Trusted by 100,000 teams.
2. Slack Lists, reminders and To-dos
Slacks own tools cover the basics. Lists track work with assignee and due-date fields, table and board layouts, and any message can be added to a list. Whether items are due is notified through Workflow Builder automations. Lists and list automations are included in paid Slack plans; Slack Pro is $7.25 per user per month billed annually. On every plan, /remind sets one-off or recurring reminders, and To-dos (which replaced Later) keep a personal to-do list with due dates.

FAQ
What's the best Slack app for assigning tasks?
Workast. It lets you create, assign and date a task in one line with /todo, and everyone in the workspace gets reminders in Slack without setting anything up. It's free for unlimited users on the Essential plan.
Can Slack assign tasks on its own?
Yes, with Lists, which have an assignee field, on paid Slack plans. /remind can remind a person or channel on any plan, but it doesn't track ownership or completion the way a task list does.
How do I get task reminders in Slack?
Workast sends each person a daily list of due and overdue tasks and a reminder before each due time, with no setup. Slack's /remind handles one-off reminders, and list automations cover Slack Lists on paid plans.
Do these apps work on Slack's free plan?
Workast's Essential plan is free for unlimited users and runs inside Slack. Slack Lists and Workflow Builder need a paid Slack plan; /remind and To-dos work on every plan.
