The rules you write are the most important part of a user story. They are the clear steps that show when a story is “done.” They are like a promise between the product team and the developers.
Good user stories need clear acceptance criteria. These rules are a promise between the product team and the developers that a user story is “done” when these rules are met. These rules are crucial because they remove any guesswork, ensuring the team delivers exactly what the user needs. Without them, it’s easy for team members to have different ideas about what a feature should do, which leads to a lot of wasted time and effort.
Our editor’s AI is built to write great rules. Instead of unclear statements like, “The user can log in,” the AI helps you create a much more specific, testable rule. A better rule would be:
This makes it easy for developers to know what to build and for testers to verify that the feature works correctly. It helps make sure the final product is exactly what you wanted, with fewer mistakes and surprises.
Unclear acceptance criteria are one of the most common reasons for project delays and frustration. When rules are vague, developers may interpret them differently than the product team intended, leading to wasted effort and rework.
Our AI helps you avoid this by using a structured, unambiguous language that leaves little room for guesswork. It prompts you to define clear actions, specific conditions, and expected outcomes, ensuring everyone on the team is on the same page from the start.
Good rules do more than just guide development; they also serve as the foundation for quality assurance (QA).

By providing a clear checklist of what to test, our editor’s AI helps the QA team confirm that a feature works as expected. This makes the testing process faster and more efficient, allowing your team to catch bugs and issues early.
With well-defined rules, the final product is more robust, reliable, and more likely to delight your users.
One of the most effective ways to write clear acceptance criteria is to use the “Given, When, Then” format. This simple structure helps you think through and articulate a specific scenario. Given a certain initial state, when a specific action is performed, then a particular outcome should occur.
This format is not just for developers; it helps the entire team, including product owners and testers, to quickly understand the intended behavior of a feature. It serves as a mini-test case written in plain language, making it easy to automate testing and verify functionality.
Acceptance criteria are the key to a shared understanding of what “done” means. A story isn’t finished just because the code is written; it’s done when all the rules in the acceptance criteria have been met. This prevents a lot of disagreements and misunderstandings, especially in teams that work remotely.
By clearly defining “done” at the start of a project, our AI-powered tool helps you build a culture of accountability and precision, ensuring every feature is completed to a high standard.
