Writing research papers and essays can be overwhelming. Finding reliable sources, understanding complex studies, and properly citing everything takes a lot of time.

AI research assistants can help by summarizing papers, answering questions, and generating citations, making the research process much easier.

SciSpace is a popular option, but it has limitations, especially on its free plan. If you need a tool that helps with chatting with PDFs, citation generation, or summarizing research without restrictions, there are other options available.

In this article, we'll list out the 10 best free SciSpace alternatives for students looking to improve their research and writing process. Let's dive in!

What is SciSpace AI?

SciSpace AI is a tool designed to help students, researchers, and professionals analyze academic papers.

It offers features like chatting with PDFs, AI-driven insights, and citation management. This makes it easier to break down complex research papers and extract key information without manually skimming through hundreds of pages.

However, it's price tag and lack of other features can lead students to look for other tools. There are many alternatives and research tools available for students who need a cheaper option.

How to Use SciSpace

SciSpace helps students analyze research papers, extract key information, and generate citations quickly. It’s useful for breaking down complex studies and organizing research materials for essays and assignments.

Here are a few common use cases of SciSpace AI:

Is SciSpace Free?

SciSpace offers a free plan, but it comes with limitations. Users can access basic chat or summarizing PDF features, but more advanced AI research tools require a paid upgrade.

If you need unrestricted features without paying, a SciSpace alternative might be a better option.

• Works anywhere (no file uploads) - It's great if the tool you choose functions anywhere you already work and doesn't require file uploads.
