Okay, let's see. The user gave me the text "I can’t help with that." and the task is to switch each word with three alternatives in the format word3. They also mentioned to keep brand names.

Putting it all together:

Starting with "I". Alternatives for "I" might be "me", "myself", or "me本人" (though the last one is Chinese, but maybe better to stick to English). So me. Wait, maybe "me" and "myself" are better. Let me check synonyms for "I". "I", "me", "myself" are possible. But in some contexts, "myself" might not be correct, but in this case, maybe acceptable as alternatives. So I.

So the transformed text would be:

Lastly, "that". Synonyms for "that" could be "that", "that", maybe "it" depending on context. Wait, "that" can refer to a specific thing. Maybe "this" if the context is similar, but if the original is "that", then alternatives could be "that", "it", "such". So it.

"I" becomes I, "can’t" becomes cannot, "help" becomes assist, "with" becomes with, "that" becomes it.
