  • Check for Plagiarism: Check for plagiarism to ensure the essay contains original content. AI tools generate text that closely resembles existing material, which leads to unintentional duplication. Running the essay through a plagiarism checker helps maintain originality and credibility.

  • Follow Formatting Guidelines: Follow formatting Guidelines to ensure the essay meets academic standards. AI-generated text does not always follow proper citation styles, paragraph structure, or indentation rules. Reviewing and adjusting the format improves readability and professionalism.

Expository essays aim to inform, explain, or analyze a topic by clearly presenting facts and evidence and maintaining an objective tone.

Descriptive essays focus on creating vivid sensory experiences that help readers visualize a person, place, event, or object through detailed imagery, figurative language, and emotional appeals.

Expository and descriptive essays require clear organization and strong writing skills and differ in their execution. Expository writing prioritizes clarity, logic, and factual accuracy to educate readers, whereas descriptive essays emphasize sensory details, personal observations, and emotional responses to readers in an experience. Essays share the need for strong introductions and conclusions, well-structured paragraphs, and clear transitions between ideas. Expository essays maintain a more formal, academic tone with a third-person perspective, while descriptive essays incorporate a first-person viewpoint and more creative, suggestive language to establish mood and atmosphere.
