Reading a research paper feels more like a test of patience than learning. You are open to a particular page and hope it will give you the correct information. Sadly, you get bombarded with jargon, and have been there already? We have a solution for you.
Research papers are hard to read, whether you are a student working on a dissertation, a researcher trying to curate the best literature review, or a company founder going through a detailed legal contract. Enter AI PDF summarizer tools.
Dump all those lengthy PDFs in these tools and let them summarize. You no longer need to review abstracts, gather citations, or get drowned in footnotes. These tools summarize but also identify the critical areas, simplify confusing terms, and let you converse with the text in a PDF.
However, you need the right AI PDF summarizer tools to complete your job in seconds. So, we have curated a list of 12 top research paper and PDF AI summariser tools. But before we get into this list, let’s find out how AI summarizes these PDFs.
How do AI summarizers work?
Generally, these AI summarizers rely on the mechanisms of NLP or Natural Language Processing and machine learning models. Combining both allows these tools to scan, interpret, and simplify complicated documents to produce easily digestible text. The core functioning of AI summarizers is based on these two methods:
- Extractive summarization: Since this acts like a digital highlighter, AI scans the entire text and extracts the most essential portions from the PDF document.
- Abstractive summarization: This is a more innovative approach. Instead of extracting lines straightaway from the document, AI reads the text, understands its context, and rewrites it like an original text.
These days, AI summarizers mostly rely on transformer-based NLP models. The primary USP of these models is their capacity to deal with vast volumes of text. This means these tools understand the flow of language and the perfect structure of a summary. An even better aspect of these AI summarizers is the chat interface. Now, you can talk with your PDF documents. Ask necessary questions and get relevant answers in seconds.
Why is summarizing a research paper hard?
Summarizing a blog post on “Top 10 home gardening rules” is a cakewalk. But what about summarizing a 110-page academic thesis on the neurochemical pathway? That’s too tiring. Here’s the truth:
Research papers aren’t written for entertainment purposes. They are technical, dense and complex. Even the academic learned people must re-read these research papers multiple times to catch subtle mistakes. This is what makes summarizing research papers so painful:
- Dense jargon: The way most of the research papers are written assumes that you have a doctoral degree. Naturally, they are stuffed with complex words and phrases that require you to be fluent in the research dialect.
- Long and rigid structure: While you sit with a research thesis, you can’t jump to the last page in a day. These research papers are packed with a strict format beyond a layman's understanding.
- Too much context: Every sentence contains enriching information in extensive research papers. You miss one, and the whole perspective of the paper changes. Again, it’s humanly impossible to understand every point clarified in a research paper.
- Manual workload: If you have to summarize a PDF, it’s nothing less than an academic cardio. First, you read the whole research, make notes, write a rough draft and then rephrase it. Don’t forget the citations and the referencing styles. Yes, it’s way too much work.
