Diffchecker – Compare, merge and explain

One of the recent updates to Diffchecker includes an improved highlight mode. When browsing a diff of two text documents, you can use this mode to compare each change individually, make edits and decide which version to keep.

You can also use a new AI feature that uses an LLM model to provide a written explanation of the difference between two versions. Same as when using other text-based interfaces employing Artificial Intelligence, like ChatGPT, you can regenerate the output or provide feedback.
