Start with the paragraph idea, choose a tone, and check that the result gives the paragraph one clear point to develop.
Type a few keywords, a question, or a short idea. Include the subject and the main point you want the paragraph to explain, support, or compare.
Academic works well for essays and homework. Professional fits reports and workplace writing. Simple is useful for ESL, younger students, or quick practice.

Use this page for a focused paragraph opening—not a full essay, full paragraph, or general sentence generation.
Use the generator when you already know the paragraph topic but need a cleaner first sentence that introduces the claim or controlling idea.
A quick topic sentence can help you avoid vague openings and get to the main point faster in school or workplace writing.
Students can use the tool to study how a topic sentence introduces the idea that later sentences develop.
Use these checks before you keep the generated sentence as the first line of your paragraph.
The sentence should name the paragraph idea clearly without listing every detail that belongs in the paragraph body.

The best topic sentence for a class essay may sound different from one used in a workplace summary or a simple ESL exercise.
The generator can save time, but you should still review the sentence before you submit or publish it.
A thesis statement controls the whole essay, while a topic sentence controls one paragraph. If the result sounds too broad, narrow the focus before you use it.
If your paragraph uses a specific example, source, or statistic, edit the topic sentence so it matches the real support you plan to include.
