Topic Sentence Maker
Develop clear and concise topic sentences that guide your paragraphs with our Topic Sentence Maker.
What Is the Topic Sentence Maker?
The Topic Sentence Maker is a free AI tool that generates opening sentences for body paragraphs - the sentence that states the paragraph's point and links it to your thesis. Topic sentences are the skeleton of an essay: read only your thesis and your topic sentences, and a marker should see your entire argument. Enter your thesis and the paragraph's point, and the tool generates options that make the claim, establish the paragraph's scope and connect back to your argument. It fixes the most common structural weakness in student essays: paragraphs that begin with evidence instead of claims.
How to Use the Topic Sentence Maker
- Enter your thesis and the point this paragraph will make.
- Click generate to receive topic sentence options.
- Choose the option that states the point and links to your thesis.
- Place it as the paragraph's first sentence - everything after it must serve it.
Topic Sentences: The Essay's Skeleton
A topic sentence does two jobs at once: it states the paragraph's claim (not its topic - its claim about the topic) and it connects that claim to your thesis. "Another factor is cost" is a topic; "Carbon pricing fails precisely where it matters most: the industries with the highest emissions" is a claim. Test your draft with the skeleton exercise: paste only your thesis and topic sentences into a fresh document - if they do not read as a coherent mini-argument, your structure has a hole. Begin paragraphs with claims, never with quotations or evidence; evidence belongs in the middle. Vary your openings, and use transitions between paragraphs to show logical movement.
Frequently Asked Questions
Is the topic sentence maker free?
Yes - free with no account required. A fair hourly allowance per visitor applies.
What is the difference between a topic sentence and a thesis?
The thesis states the essay's overall argument; each topic sentence states one supporting point. Topic sentences are miniature theses for their paragraphs.
Should a paragraph ever start with a quote?
No - open with your own claim, then bring in evidence. A paragraph that opens with a quotation has outsourced its argument.
How long should a topic sentence be?
One sentence, typically 15-30 words. If it takes two sentences to state the point, the paragraph is probably trying to make two points.
