Standout Differences
Three different jobs, not three rivals
Miro is a visual whiteboard, Slack is a messaging platform, and Todoist is a task manager — none of them substitute for either of the others. Buyers who land on this comparison are more likely deciding whether to add a second or third tool to an existing stack than choosing one over the others.

Free tiers have very different ceilings
Miro's free plan caps out at just 3 editable boards, which is enough to evaluate the product but not to run ongoing work. Slack's free plan is more usable long-term but loses message history after 90 days and restricts DMs to one-on-one only. Todoist's free tier is generally the most workable for solo use of the three.

AI is layered into paid tiers on both Miro and Slack
Miro adds AI credits at the Starter tier and AI-powered workflows, agents, and MCP connectivity at the Business tier. Slack adds an AI-powered Slackbot personal agent at Business+ and enterprise-grade AI at its top tier. No AI capability is documented for Todoist in the data provided.

Frequently Asked Questions
Do Miro, Slack, and Todoist actually compete with each other?
No. They belong to different tool categories — Miro is a visual whiteboard for brainstorming and diagramming, Slack is a team messaging platform, and Todoist is a task manager. Most teams use two or three of them together rather than choosing just one.
Which of the three is cheapest for a small team?
Todoist Pro starts at $5/user/month billed annually and Slack starts at $7.25/user/month billed annually, both below Miro's $8/month per member starting price. All three also offer a free plan, though Miro's free tier is limited to 3 editable boards.
Can I use Miro, Slack, and Todoist together?
Yes, and this is the more common setup than choosing one exclusively. A typical stack uses Slack for day-to-day communication, Miro for workshops, retros, and planning sessions on a shared canvas, and Todoist for individual task tracking that doesn't need a full project management suite.
Which has the most usable free plan long-term?
Slack's free plan is usable for small teams on an ongoing basis, though it caps message history at 90 days and limits DMs to one-on-one conversations. Miro's free plan is capped at only 3 editable boards, which suits a single small project or evaluation rather than continuous use. Todoist's free tier is generally workable for individual task management without a hard project cap mentioned.
Does Slack replace the need for Todoist or Miro?
Not based on their core feature sets. Slack centralizes communication and includes Huddles and file sharing, but it isn't built as a dedicated task manager like Todoist or a visual canvas tool like Miro. Teams typically layer Slack notifications on top of, rather than instead of, dedicated planning and task tools.
