Create your RACI matrix online
Tasks down the side, people across the top. One click in a cell sets the role: R, A, C or I. The tool checks as you go that no task is left without an owner and that only one person approves. No sign-up.
Click a cell to cycle through R → A → C → I, then empty. On a keyboard, type R, A, C or I directly, clear with Delete and move with the arrow keys. You can also paste from Excel: select the first cell and paste.
What is a RACI matrix for?
A RACI matrix answers a question everyone assumes is settled until the day it isn't: who does the work, and who decides. It comes out when a project is being scoped, when a new supplier joins, or right after the meeting where two people discover they were each waiting for the other to handle it.
The value isn't the grid itself, it's the conversation it forces. Filling in the "approve the scope" row means naming one person, and only one. That is usually where the disagreement surfaces — and it is far better that it surfaces there.
What do R, A, C and I mean?
- R — Responsible: does the work. There can be several on one task.
- A — Accountable: answers for the outcome and signs it off. Exactly one per task — this is the rule the whole method rests on.
- C — Consulted: gives input before the decision. A two-way conversation.
- I — Informed: hears the outcome afterwards. A one-way message.
The same person often holds both R and A on a task: they do it and they answer for it. That is perfectly valid, and common in small teams.
How to build one
- List your people — roles rather than first names, so the matrix outlives the leavers.
- List your tasks, one per line. Use action verbs: "approve the scope", not "scope".
- Click the cells to place the roles. Start with the As: that's the column that stalls, and once the decision-makers are placed the rest goes quickly.
- Read the warnings under the grid, pick your colours, then download or copy.
The mistakes the tool flags
A broken RACI matrix is one that looks complete. Three mistakes only show up in the meeting, never before; the tool flags them as you type, without blocking anything:
- Two As on one task. Two decision-makers means none: the moment they disagree, the task stops.
- No R on a task. Everyone approves, nobody does the work.
- Someone who appears nowhere. Either they don't belong in the project, or a task has been forgotten.
Frequently asked questions
Is one A per task really achievable?
Yes, and that's the point of the method. An A shared between two people is a decision with no owner: each assumes the other will call it. If two departments genuinely have to sign off, that's usually a sign the task should be split in two.
Should every cell have a letter?
No, and it's better not to. A matrix where everyone is at least "informed" everywhere stops saying anything. Leave a cell empty when it doesn't concern that person.
How many tasks and people can I add?
Up to 16 tasks and 8 people. Beyond 6 or 7 people the matrix gets hard to read on a projector — group them into roles instead.
Can I start from an existing table?
Yes. Copy the range from your Excel file, click the first cell of the grid and paste: the letters R, A, C and I are recognised, anything else is ignored.
Can I come back to my work later?
Yes. What you type is kept in your browser, and the Save button lets you keep several matrices. Ctrl+Z undoes the last action, including a paste.
Is it really free?
Yes, no sign-up and no limit on how many matrices you make. The free version adds a small mention of the site at the bottom of the image and keeps up to 3 saved matrices.
