Mab is not flexible,
Mab is Finished.
One task, one responsible person, one status, and one single action at any given time.
Mab.io uses a fixed, non-customizable role system
based on a simplified RACI model.
Every task involves clearly defined responsibilities with zero overlap or ambiguity.
- The only person responsible for executing the task
- Can't reassign or change the structure — only do the work and move it forward
- Assigns the Assignee
- Reviews and approves the final output
- Handles escalations (e.g., when a task is Blocked)
- Provide support
- Can request changes, pushing the task to Awaiting Revision
- Cannot approve or complete the task
- Observes the task
- Gets notified of updates
- Send messages
Task is being defined. Not yet assigned. Only the Owner can move it forward.
Task is created and assigned, but Assignee hasn't accepted it yet. Only the Assignee can transition to Doing.
Work is actively being done. Only the Assignee can trigger this.
The Assignee needs help from the Advisor.
The Assignee has finished. Now it's up to the Owner to approve or reject.
Owner or Advisor has requested changes.
No individual is directly responsible — the task is temporarily shelved until progress is made in its subtasks.
The Assignee cannot proceed due to an external issue or dependency. Requires Owner intervention to resolve.
Work is done and approved.
Task has been cancelled or deemed invalid.
Most productivity tools give you freedom. Mab gives you discipline.
No Endless Setup
- You don't spend 2 days building a workflow before starting work.
- You don't need a "Notion architect".
- You just create a task — Mab knows the rest.
No Multi-Assignee Confusion
- In Mab, one task = one responsible person at a time.
- You'll never find a task with three people "sort of" owning it.
No Freeform Status Chaos
- You can't create your own statuses.
- There are 10 predefined statuses — and that's it.
- Each status has rules. Each role has power. No exceptions.
No Fake Progress with "Checklists"
- Mab supports subtasks — but they behave like real tasks.
- You can't check off 10 boxes and call it progress.
- Work must flow through rules, not feelings.
No Passive Collaboration
- If you're a Follower, you follow.
- If you're the Assignee, you work.
- Mab won't let people touch what they shouldn't.
- There's no "accidental editing" or "oops I moved your task."
No Indecision Loops
- Tasks waiting for feedback or help? They go to Awaiting Advice.
- Waiting for review? Awaiting Approval.
- You don't lose tasks in comment threads. Every handoff is structured.
