Ludwig's WRAP-UP
The phrase "I design that" is generally considered grammatically incorrect in standard English, according to Ludwig AI. While it appears in some contexts, particularly News & Media and Science, it's recommended to use the past tense ("I designed that") or rephrase for clarity (e.g., "I created that design"). The intended purpose is to assert authorship, but the phrasing introduces awkwardness. Consider alternatives like "I designed that" or "that is my design" for improved correctness and impact. Therefore, it is suggested that you avoid "I design that" in formal writing.
