AI thesis checker scoped to the claim

The evaluation is of an argument, not of a document's surface. A submitted statement is examined for whether it is contestable, whether it is specified tightly enough to be defended, whether its scope is proportionate to the piece it heads, and whether the reasoning presented around it entails it rather than merely accompanying it.

The route is server-side. Text is transmitted to our AI server, input is accepted between 1 and 12,000 characters, and the allowance is 5 free runs per rolling 24-hour window with no account. The returned result is written analysis, because the classifier that powers this route produces prose and computes no scores.

The pages competing for this term divide cleanly. One group proofreads a complete thesis manuscript. The most detailed of them advertises grammar, spelling, style guide preferences, technical phrasing, word choice, word count reduction, academic tone, unbiased language, US and UK variant handling, vague language, sentence structure and plagiarism detection via a text similarity algorithm, with results delivered as a table of revisions grouped by language category and a file upload path for the manuscript. Another grades against a user-defined rubric and bundles plagiarism and AI detection, with several of its features marked as not yet shipped.

The second group addresses the one-sentence thesis statement, and a large share of those pages generate a statement rather than assess one. This route sits in neither group cleanly: it assesses rather than generates, and it assesses an argument rather than a manuscript. The 12,000-character ceiling enforces that boundary whether or not a visitor intended it, which is why the boundary is stated here rather than discovered at the point of failure.

Submit the statement together with its surrounding paragraph. Support cannot be assessed against a claim presented in isolation.

Step 1

Paste the statement and its context, between 1 and 12,000 characters.

Step 2

Optionally supply the assignment question and word count in the 300-character instruction field, then execute.

Step 3

Revise against the findings. If the claim itself moved, resubmit, since a scope judgement made against the old claim no longer applies.

Stated in advance, so the report is read against a declared standard rather than an assumed one.

Contestability

An informed reader could hold the opposite position. A statement nobody would dispute is a topic description wearing the grammar of a claim.

Specification

The claim identifies its case, its period and the respect in which it holds. Unspecified claims cannot be falsified and therefore cannot be defended.

Proportionate scope

The promise made matches the length available. Overscoped claims produce uniformly thin sections rather than one visibly weak one, which is why the fault is hard to locate from inside the draft.

Entailment of support

The reasons offered lead to the claim rather than sharing a subject with it. This is the failure most likely to survive into a well-written draft.

No plagiarism or text similarity detection: there is no reference corpus in this codebase and no comparison is performed. No rubric engine and no numeric grade. No table of revisions and no tracked changes, because the output is prose. No manuscript file upload, no style guide enforcement, no US or UK variant normalisation, no citation format validation, no unbiased-language checking, no word count reduction pass.

Each item in that list is claimed on at least one page currently competing for this keyword. Listing them is not modesty, it is the difference between a page that survives first use and one that does not. The classifier is additionally instructed never to assert certainty about plagiarism or authorship, so even where a run touches on originality it describes signals rather than issuing a verdict.

Composition order explains most of it. A statement written before the argument exists can only restate the topic, since the writer has not yet established a position. The draft then discovers one, and by the conclusion the writer is defending something narrower and sharper than the introduction advertised.

The practical consequence is that a thesis check performed early tests a placeholder. Performed after drafting, it tests the claim the writer actually made, which is normally recoverable from the final paragraph. Submitting the conclusion alongside the introduction is the highest-value use of a single run.

No. No grade is produced, no rubric is applied, and no mark is predicted, because a mark is a judgement a human has not yet made and inventing one would be fabrication. The report describes properties of the argument and where they are underspecified.

It likewise makes no prediction about plagiarism systems or AI detectors. We do not operate those systems, do not test against them, and treat any claim about their output as unverifiable.

Undergraduates checking, late in a draft, whether the introduction still describes the essay that exists. Postgraduates pressure-testing a research question before it is put to a supervisor, where an overscoped claim is expensive to discover later.

Tutors taking a second read on why a student's argument keeps drifting between sections. In all cases the institution's own policy on AI-assisted tools governs, and this product neither sets nor interprets it.
