Understand the Structure of Any Scientific Introduction
IMRAD Analyzer classifies every sentence in your introduction into its rhetorical move — helping researchers write with precision and reviewers assess with clarity.
Sentence Classification
Machine learning has transformed many domains of computer science.
However, existing models require large labeled datasets.
In this paper, we propose a novel semi-supervised framework.
Our method achieves state-of-the-art results on three benchmarks.
Everything You Need to Write Better Introductions
From PDF upload to sentence-level analysis, IMRAD Analyzer gives you a complete picture of your introduction's rhetorical structure.
PDF Upload
Upload any research paper as a PDF. We automatically extract the introduction and send it for analysis — no copy-paste needed.
Direct Text Input
Paste or type your introduction directly into the editor. Get instant sentence-level feedback as you write.
Sentence-Level Classification
Every sentence is classified into Move 1, 2, or 3 with a confidence score, following the Swales CARS model.
Sub-move Detection
Each rhetorical move is broken down into specific sub-moves, giving you granular insight into your introduction's structure.
AI-Powered Summaries
Premium users receive an AI-generated summary and class-based analysis to help interpret results and guide revision.
Analysis History
Every analysis is saved automatically. Revisit past introductions, track revisions, and compare improvements over time.

- Raise questions about unclear research
- Extend or continue prior research
Occupying the Niche
- Outline purposes and nature of research
- State hypothesis or research question
- Share main findings
- Elaborate on research value
- Outline the paper structure
Trusted by Researchers Worldwide
“IMRAD Analyzer helped me identify that my introduction was missing the niche-establishment move entirely. I restructured it and the paper was accepted on first submission.”
Dr. Sarah Chen
Assistant Professor, Stanford University
“I use it with my PhD students to teach them how to structure research introductions. The sentence-level breakdown makes rhetorical moves tangible and easy to discuss.”
Prof. James Miller
Linguistics Department, University of Oxford
“As a non-native English speaker, understanding the expected flow of a scientific introduction was always a challenge. This tool gives me objective feedback instantly.”
Dr. Amara Diallo
Research Fellow, Université Paris-Saclay
