AnswerThis vs SciSpace Comparison For Researchers

The invention of AI research tools has been revolutionary for shaping the future of academic research for students, faculty, researchers and academics. As artificial intelligence is changing the way we do research and interact with the academic community, the old ways of manually researching, reading and finding articles are no longer effective. Today we are able to use smarter tools to quickly and easily find literature that is related to our field of study and make sense out of challenging articles, all while having an automated writing tool to help with writing.

Two popular AI research assistants that often come up in comparisons are AnswerThis and SciSpace.

Key Features

• Automated literature reviews

• Research question answering

• Citation-backed summaries

• Research gap identification

• Reference and PDF library management

What is AnswerThis?

AnswerThis is like having a dedicated research analyst. Unlike the traditional approach to literature reviews where you just get a list of academic articles, AnswerThis provides answers directly to your questions using scholarly sources, and it combines the information from multiple academic articles into a structured format that includes citations.Because of this, AnswerThis is very useful for: writing literature reviews, writing research proposal, and writing review/survey papers. 

Our Take on AnswerThis

This is an excellent tool for researchers who prefer organized academic-style writing to synthesize. It simplifies the early part of the research phase because it organizes the supporting evidence and summarizes the major findings. However, it is not as interactive as when one reads papers in detail.

Pros: Excellent synthesis of literature, citation support, helps identify research gaps. End to end research support.

Cons: Has a slight learning curve for new users.

SciSpace – Overview

Rating: 4.0 out of 5

Pricing:
Free plan available. Paid plans start at $12 per month.

Key Features

• AI-powered literature search

• Chat with PDFs

• Automated summarization

• Citation generation

• AI research copilot

What is SciSpace?

SciSpace tries to comprehend and manipulate scientific knowledge. Perhaps more importantly, you can now also connect directly to the pdfs via chat. You may use this chat service to ask questions of the document, clarification of terms and clarification of either tables, equations and graphs. This feature makes SciSpace a valuable resource for all students or researchers who are dealing with complex reading of dense academic articles. 

Our Take on SciSpace

SciSpace provides students access to short summary information for many papers and can easily be read and reviewed thanks to its straightforward interface and chat tool that integrates with PDFs. Users will save time on their reading, however they should not use it as a stand alone research synthesis tool, or for academic writing from scratch.

Pros: Simple interface, easy communication with PDFs, complex materials simplified

Cons: Many free plan limitations, advanced plans may be too expensive for students,most SciSpace writing capabilities are limited

Feature Comparison: AnswerThis vs SciSpace

The right AI research tool is critical to the success of your academic work, as it affects both your quality and speed of research. This section provides a side-by-side comparison and detailed review of AnswerThis and SciSpace with respect to their performance on important research tasks.

1. Literature Review Capabilities

AnswerThis: AnswerThis is a purpose-built tool designed to facilitate structured literature reviews by gathering and synthesizing information gained through multiple peer-reviewed journals into an organized format with citations. As a result, it is ideal for use in theses, systematic reviews and research proposals where synthesizing results from many studies is important.

SciSpace: SciSpace provides a literature discovery platform and assists in navigating between associated journals; however, its main goals remain focused on understanding the contents of each separate document as opposed to providing a synthesis of all related studies within a larger body of research.

Winner: AnswerThis

2. AI Models and Language Understanding

AnswerThis: The AnswerThis AI models have been developed to evaluate research literature based on the evidence (e.g., methods & results) that establishes a conclusion. 

SciSpace: In contrast, the conversational interfaces of the SciSpace AI have been developed to provide guidance and explanation regarding research terminology but are less focused on synthesizing research findings from multiple studies.

Winner: AnswerThis

3. Information Extraction

AnswerThis: With its ability to extract key findings, methodologies and trends across a number of academic papers simultaneously; AnswerThis allows users to compare papers, identify cross-study themes and provide a means for thematic analysis of papers.

SciSpace: SciSpace focuses on how the context of each paper impacts the findings of interest, allowing users to identify key themes and understand how and why related findings are important.

Winner: Tie

4. Summarization

AnswerThis: AnswerThis summaries provide an overview of research with a focus on academic structure and format. The summaries are designed for academic purposes and can also be included in an academic literature review.

SciSpace: SciSpace reader-friendly summaries help you read quickly and efficiently. These summaries make good introductory summaries for your academic papers but are generally not as useful for saying stuff the way you would in an academic context.

Winner: AnswerThis

5. Keyword Matching and Topic Mining

AnswerThis: AnswerThis shows how to identify research themes and patterns and where there are potential gaps in research, thus providing value when brainstorming or developing an initial list of potential research questions.

SciSpace: SciSpace has a more organic approach when providing keywords related to content that is read. It does not enable you to systematically identify topics and to systematically identify research gap(s).

Winner: AnswerThis

6. Automating Research Workflows

AnswerThis: AnswerThis automates the multi-paper syntheses, structured summaries, and citing sources for researchers, minimizing researcher time required to create an academic or scientific document from several sources.

SciSpace: SciSpace improves how researchers read research papers by providing tools, including the ability to chat with a PDF and receive instant clarification/explanations on terminology used in papers.

Winner: AnswerThis

7. Interactive Questions and Answers

AnswerThis: AnswerThis offers users the ability to conduct academic-level research by providing citation-sourced responses based on numerous academic sources of information.  This tool is extremely useful for collecting evidence and supporting arguments in academic publication.

SciSpace: On the other hand, SciSpace offers a way to have a direct, interactive conversation regarding a specific paper that uses a PDF so the user can clarify the paper's content.  However, SciSpace does not support coherent reasoning between multiple papers.

Winner: AnswerThis
