  • Single-paragraph academic abstract, 150-250 words: background → objective → method → results (with numbers) → conclusion.
  • Generated from your full text, so results and numbers come from your own paper.
  • No citations, no bullet points — journal-style prose.
  • Can also produce a structured abstract on request (Background / Methods / Results / Conclusions).
  • A draft to edit, not a final text — check journal word limits and rules on AI assistance.

What a good abstract contains

Editors and reviewers read the abstract to decide whether to read on. Most journals expect, in one paragraph: the context in one sentence, the objective, the method (design, data, sample), the main results with numbers, and the conclusion with its implication. Avoid citations, undefined abbreviations and claims stronger than your results.

Using AI responsibly in academic writing

Many journals and universities require you to disclose AI assistance and forbid listing AI as an author. Use the generated abstract as a draft: rewrite it, verify every statement, and follow your target journal's policy.

Frequently asked questions

Can it respect a word limit?

Ask in the Q&A tab: “Rewrite the abstract in 150 words maximum.” Always count the final version yourself.

Does it work for conference papers and theses?

Yes. For theses, summarize the full document first with the thesis summarizer if you need an overview, then generate the abstract.

Can it write the abstract in another language?

Yes. Many journals require an English abstract for papers written in another language — choose English as output.

Will it invent results?

It is instructed to use only what your document says. Check every number against your results section anyway.
