Paste an abstract to see how clearly it is structured. A good abstract usually moves through five parts: the background, the objective, the method, the results and the conclusion. The checker labels every sentence with the part it plays, rates how clearly each part comes across, and suggests what to improve.

The four examples are rewrites of the abstract of the XAI 2.0 manifesto (Longo et al., Information Fusion, 2024), each written to show what moves an abstract from one rating to the next, up to the optimal version at 100%.
- Background
- Objective
- Method
- Result
- Conclusion
How it works
The checker reads the abstract one sentence at a time and looks for typical phrases that signal each part, such as “we propose” for an objective or “the results show” for a result. Each sentence is labelled with the part it signals most; where it signals none, its position in the abstract decides the label.
Clarity rewards two things. The first is strength: one signal gives 50%, two give 80%, three or more give 100%. The second is focus: if some of a sentence’s signals point to another part, its clarity drops in proportion. A sentence at 100% therefore signals its part at least three times and nothing else. A sentence with no signal scores 0%. Overall, 60% or more is clear, 45% to 59% fair, and below 45% unclear.
The checker follows fixed rules rather than understanding meaning, so it is best treated as a second opinion. It works well on conventional scientific abstracts and can misread unusual writing.
