A strong literature review is not written by chance. It is built through careful reading, correct citations, and a clear understanding of past research. For many researchers, this stage is also the most time-consuming and exhausting part of academic writing. Searching hundreds of papers, tracking citations, and identifying relevant studies can easily take weeks or even months.
In 2026, artificial intelligence has completely changed this process. Today, researchers can find relevant literature, explore citation networks, and understand complex research papers within minutes. The best part is that some of the most powerful tools are still available for free.
This article explains how to complete a fast, effective literature review using two widely used AI tools.
Why Literature Review Matters in Academic Research
A literature review with relevant sources and proper citations is the backbone of any research document.
It helps you:
Understand what has already been studied
Identify research gaps
Avoid duplication of work
Strengthen the credibility of your research
Support your arguments with evidence
Without a strong literature review, even a good research idea loses its impact.
What Researchers Need From AI Tools in 2026
Modern researchers are not just looking for papers. They want tools that:
Provide the latest and relevant research
Work across all academic disciplines
Offer citation tracking and visualization
Are free or affordable
Save time without compromising quality
The tools discussed below meet all these requirements.
Tool 1: Litmaps – Your AI Literature Review Assistant
Litmaps is one of the most advanced free AI tools for literature discovery. It is currently used by more than 250,000 researchers, students, and professionals worldwide.
How Litmaps Works
Litmaps allows you to search research papers using keywords and instantly explore how papers are connected through citations. The tool goes beyond simple keyword searches by showing relationships between studies.
You can use Litmaps without logging in, but signing in with your Gmail account unlocks powerful features.
Feature 1: Seed Map for Literature Discovery
The seed map feature is the core strength of Litmaps.
Step-by-Step Process:
Enter your research keyword
Browse thousands of related papers
Select one highly relevant paper as your seed paper
Generate a seed map

For example, when searching for applications of phosphonium-based ionic liquids, Litmaps can show more than 8,000 related research papers.
Once you select a seed paper, Litmaps automatically finds:
Earlier foundational studies
Closely related papers
Latest publications based on citations
The visual map shows:
Left to right: older to newer publications
Bottom to top: low to high citation impact
This helps you quickly identify influential and recent studies.
Feature 2: Exploring Connected Research Papers
Each paper in the map is clickable. When you select a paper, you can:
Read its abstract
View citations and references
Check publication details
Open the source

If a paper is freely available, you can directly download it. This saves hours of manual searching across different databases.
Feature 3: Smart Citation Discovery
Litmaps also offers a citation discovery system that reduces citation chasing.
You can:
Enter a keyword or upload your research paper
Select relevant outputs
Analyze papers based on:
Content similarity
Common authors
Citation relationships

This allows you to identify papers that are closely aligned with your research focus.
Feature 4: Building Your Personal Literature Library
Litmaps allows you to create your own cloud-based literature library.
You can:
Save papers by author, year, title, and citations
Organize references into collections
Visualize your entire literature set
Access your library from anywhere

The visual layout helps you see which papers are most cited, newest, or least explored.
Why Litmaps Is Ideal for Fast Literature Reviews
Litmaps helps researchers discover papers that are often missed during manual searches. It provides a clear overview of how research evolves and how studies are connected.
Tool 2: Explainpaper – Understand Research Papers Faster
After collecting literature, the next challenge is reading and understanding complex research papers. This is where ExplainPaper becomes extremely useful.
How Explainpaper Works
ExplainPaper is a free AI-powered tool that helps you understand research papers section by section.
Steps to Use:
Upload a research paper in PDF format
Click “Begin Reading”
Highlight any complex section
Ask for an explanation

The tool uses AI support to explain content in a clear and precise way.
Key Benefits of ExplainPaper
No daily usage limitation for basic explanations
Clear explanations of complex methods and results
Useful for beginners and advanced researchers
Saves time during paper evaluation
You can customize explanations based on your understanding level. While advanced features require a paid plan, the free version is more than sufficient for regular academic use.
How These Two Tools Work Together
Using Litmaps and Explainpaper together creates a complete literature review workflow:
Discover literature using Litmaps
Build and organize your library
Evaluate papers using Explainpaper
Understand methods and results clearly
Write a strong, citation-rich literature review
This process is faster, more accurate, and less overwhelming than traditional methods.
Who Should Use These AI Tools
These tools are ideal for:
Undergraduate and postgraduate students
PhD and MPhil researchers
Academic writers
Research supervisors
Professionals involved in R&D
They work across all subjects, including science, engineering, social sciences, medicine, and humanities.
