The abstract
A single paragraph (or a structured block with headings in medical and some scientific journals) that states the context, objective, method, main results with numbers and conclusion. No citations, no undefined abbreviations, no claims beyond the results. It is indexed by databases and often the only part people read, so precision matters.
Draft one from your manuscript with the abstract generator, then edit it to your journal's rules.
The executive summary
Written for someone who may read nothing else. It leads with the conclusion or recommendation, then gives the situation, key findings with figures, the decision needed, expected impact, risks and next steps. It must stand alone: no “see section 4”.
The executive summary generator follows this structure from any report.
The synopsis
Common in publishing and film: a narrative overview of the whole story, including the ending, written in the present tense. In research funding, a “synopsis” can also mean a short project description. Its job is to show the arc, not to persuade with data.
The summary
The generic form: a condensed version of a text. Its length and structure depend on the use — five bullet points for a chat message, three paragraphs for a briefing. See how to write a good summary.
Frequently asked questions
Is an executive summary the same as an abstract?
No. An abstract describes a study so readers can decide whether to read it; an executive summary gives decision-makers the conclusion and recommendation so they can act.
How long should an executive summary be?
Usually one to two pages, or roughly 5-10% of the report's length. Shorter is better if it still stands alone.
Does an abstract include results?
Yes — the main results, ideally with numbers, are the most important part of an abstract.
Can AI write an executive summary?
It can draft one from the full report. The author should verify figures and adjust the recommendation and tone.
