Key Differences

Chilli, often spelled "chili" in American English, encompasses a variety of Capsicum species that are noted for their pungency provided by the compound capsaicin. Peppers include a broader category, such as bell peppers, which are mild, and black pepper, a completely different spice derived from the Piper nigrum plant.
The term "chilli" specifically refers to hot and spicy fruits used in cooking to enhance flavor and heat. On the other hand, "pepper" might refer to sweet or mild Capsicum like bell peppers or the sharp-flavored black pepper used as a common table seasoning.
Culinary uses of chilli vary from being a primary ingredient in dishes like curries and hot sauces to a flavor enhancer in a wide range of cuisines. In contrast, peppers such as bell peppers are used for their sweet flavor and crunchy texture, while ground black pepper is utilized for its bold, earthy spice.
Chilli plants typically produce fruits in various colors, shapes, and sizes, each with a distinct level of heat. Pepper plants, such as those producing bell peppers, grow fruits that are larger and have a sweet or neutral taste, whereas the Piper nigrum produces small, round, black peppercorns.
Chillies are integral to the cuisines of many cultures, especially in Asia and the Americas, where they are celebrated for their ability to add heat and depth to dishes. Conversely, both bell peppers and black pepper hold global culinary importance but are used differently; bell peppers are common in salads and cooked dishes, while black pepper is almost ubiquitous as a seasoning.
