Step-by-Step Installation Guide

Let’s walk through setting up the asXiv environment step by step:

  1. Get the Source Code

    First, you need to copy the asXiv repository to your local machine. Open your terminal (command line interface) and enter the following command:

    git clone git@github.com:montanaflynn/asxiv.git
cd asxiv

    This command creates a folder named “asxiv” containing all necessary files.

  2. Install Dependencies

    After entering the project folder, you need to install the software packages required for the project to run:

    npm install

    This process may take a few minutes, depending on your internet speed. These dependencies include React, the Next.js framework, and other essential libraries.

  3. Configure Environment Variables

    Following security best practices, asXiv uses environment variables to store sensitive information like API keys:

    cp .env.example .env.local

    This command creates a new file named “.env.local”. Next, you need to open this file with a text editor and add your Gemini API key:

    GEMINI_API_KEY=your_api_key_here

    How do you get a Gemini API key? Visit Google AI Studio’s API key page and follow the instructions to create a new key. This key is free but has usage limits that are typically sufficient for personal use.

  4. Start the Development Server

    Once configured, you can start asXiv:

    npm run dev

    If everything works correctly, you’ll see a message similar to “Ready on http://localhost:3000”.

  5. Access the Website

    Open your web browser and visit http://localhost:3000 to start using asXiv.

Configuration Options

asXiv provides several customizable options, primarily through environment variables:

# Required configuration
GEMINI_API_KEY=your_gemini_api_key

# Optional configuration
GEMINI_MODEL=gemini-2.5-flash-lite

You can choose different AI models based on your needs:

  • ☾ gemini-2.5-flash-lite – Fastest, lowest cost (default option)
  • ☾ gemini-2.5-flash – Balanced speed and performance
  • ☾ gemini-2.5-pro – Highest quality, slower, more expensive

Which model should you choose? If you primarily need quick queries and summaries, the flash-lite version is the best choice. If you require deeper analysis and understanding, consider using the pro version.

Detailed Explanation of asXiv’s Core Features

Intelligent Conversation Interface

The heart of asXiv is its chat widget (ChatWidget), an intuitive interface that enables natural conversation with paper content. You can ask any questions about the paper, such as:

  • ☾ “What are the main contributions of this paper?”
  • ☾ “Can you explain the methodology in Chapter 3?”
  • ☾ “What conclusions did the authors reach?”
  • ☾ “What are the limitations of this research?”

The AI provides accurate answers based on the paper’s content, rather than generic responses.

PDF Viewer Integration

asXiv includes a powerful PDF viewer built on Mozilla’s PDF.js technology. This viewer not only supports conventional PDF navigation but also integrates closely with AI responses. When the AI references specific pages in its answers (using the “(page N)” format), these references are automatically converted into clickable links that take you directly to the corresponding page in the paper.

This design is particularly useful when the AI mentions “as described on page 5″—you can jump to that page with one click to view the original text, enabling a seamless reading experience.

Flexible Paper Access Methods

asXiv supports two main ways to access papers:

  1. Direct PDF Upload: If you’ve already downloaded the paper PDF file, you can upload it directly to the system
  2. arXiv ID Input: Simply provide the arXiv paper identifier (such as “2401.12345”), and the system will automatically fetch the paper from the arXiv server

The second method is especially convenient because you don’t need to manually download the paper first—asXiv handles all the technical details for you.
