About RACI Matrix Builder
The RACI Matrix Builder is a free, browser-based tool that helps small business owners, project managers, and freelancers define and communicate roles and responsibilities for any project or process. RACI stands for Responsible, Accountable, Consulted, and Informed - a proven framework used by teams of all sizes to eliminate ambiguity about who does what on a project.
Start by adding your team roles across the top of the matrix - these can be job titles, names, departments, or any label that makes sense for your project. Then add your tasks or deliverables down the left column. For each cell at the intersection of a task and a role, assign one of four designations: R for Responsible (the person who does the work), A for Accountable (the person who owns the outcome and approves the work), C for Consulted (people whose input is needed), and I for Informed (people who need to know the outcome but are not directly involved).
The tool validates your matrix as you build it, warning you if any task has no Responsible party assigned - a common mistake that leads to things falling through the cracks. Best practice is to have exactly one Accountable person per task and at least one Responsible person. Having too many people in the R or A role on a single task often signals unclear ownership.
Once your matrix is complete, export it as a CSV for sharing in Google Sheets or Excel, or print it as a PDF to include in project documentation, kickoff presentations, or stakeholder briefings. The matrix is pre-populated with a sample project so you can see how a completed RACI looks before building your own.
This tool is particularly useful for onboarding new team members, setting expectations with clients, scoping freelance engagements, and running workshops where role clarity is a common pain point.
