Thesis Statement Builder — Built From Your Own Argument

Knowing how to write a thesis statement mostly means knowing three things before you write it: what the essay is about, what you claim about it, and why a reader should believe you. The builder has three fields; your topic and stance are required, and evidence is optional:

• Topic (up to 200 characters) — the subject, as narrow as you can make it.
• Stance (up to 300 characters) — your position, in your own words, however rough.
• Evidence (optional, up to 500 characters) — the main reasons or findings you plan to use.

It asks the AI for three one-sentence drafts based on what you entered: an argumentative thesis that takes a clear side, an analytical thesis that explains how or why something works, and a concession thesis that acknowledges the other side before making your claim. You supply the stance. Review the drafts for unsupported claims and use them to develop your own wording.

An illustrative example, using the kind of notes an international student might type quickly:

Topic: «online learning in university»
Stance: «I think it is not so good like in-person for first year students»
Evidence: «less contact with teachers, hard to make friends, many students feel alone, but it is flexible for students who work»

Example output:

• Argumentative: «Fully online courses serve first-year university students worse than in-person teaching because they limit contact with instructors and make it harder to build the peer relationships that help students stay enrolled.»
• Analytical: «Online learning changes the first year of university by replacing informal contact with instructors and classmates with scheduled, screen-based interaction, which affects how connected new students feel.»
• Concession: «Although online courses offer flexibility that working students value, in-person teaching better supports first-year students, who depend on direct contact with instructors and peers.»

Note the second clause of the argumentative draft: if your evidence does not actually show an effect on enrollment, that phrase has to go. Every word of a thesis is a promise the essay must keep.

The AI is instructed to use your topic, stance and evidence without inventing statistics, studies or sources. Check each draft against your notes; where a draft would need a specific fact you did not give it, treat that as a gap to fill with your own research. The requested output is one sentence per option, not an essay.

Use the drafts to see the shape of a strong thesis, then write your own in your words. A thesis that you rewrite yourself is easier to defend in class, easier to build body paragraphs around, and clearly yours. If your instructor has rules about AI tools at the brainstorming stage, those rules apply here.

Academic cultures do not agree on where the main claim goes. In some writing traditions the argument builds slowly and the position appears near the end, or is implied rather than stated. English academic writing usually expects the opposite: a direct, specific claim in the introduction, often its last sentence. Writers who learned essay structure in another language are not doing it wrong — they are following a different convention.

The language itself adds a second difficulty. Hedging is one example: «I think it is not so good» is honest but vague in English, while «proves that» overclaims. A good academic thesis sits in between, with verbs like «limits», «suggests» or «better supports». Our article on hedging in academic writing covers that middle ground in more detail.

Fields are capped at 200 characters for the topic, 300 for the stance and 500 for the evidence — enough for notes, not for pasting a source. You get 10 free runs per day with no account. What you type is sent to our AI provider to generate the drafts and is not stored, logged or used for training. Fix in the editor opens your chosen draft in Diglot so you can start the introduction around it.

Once you have a thesis you believe, the next step is structure. The essay outline generator suggests section headings and points for a topic, which you can check against the promises your thesis makes. When individual sentences in your introduction feel awkward, the sentence rewriter gives you three ways to phrase each one.
