What's the simplest way to change a few words baked into an image?

I keep running into a small, specific image-editing need: a screenshot or graphic has one or two outdated words, and I want to fix the copy without taking on the learning curve of a full image editor.

The right approach depends on how the image was made. If the original file still has an editable text layer, changing the words is straightforward. If the text has been flattened into the image, it becomes a retouching problem too: the old letters need to be removed or covered, the background repaired, and the replacement text made to fit. Adobe's guidance explains the editable-text case: https://helpx.adobe.com/photoshop/desktop/text-typography/get-started-with-text/edit-text.html

For someone who only needs this occasionally, what workflow would you recommend? Is there a lightweight tool that handles this narrow job without requiring me to learn a large editor first?

I've been using PhotextAI for this kind of small text change and found it helpful, so I'm sharing it in case it helps someone else: https://photextai.com/ . I'm a user recommending a tool I've found useful, and I'm interested in other simple workflows people use.
