Introduction

In the rapidly evolving landscape of AI assistants, Claude and Perplexity have emerged as prominent contenders, each with distinct capabilities and user bases. Claude, developed by Anthropic and launched in 2022, positions itself as a safe, reliable AI assistant focused on helpful, honest, and harmless interactions. Perplexity, introduced in 2023, markets itself as a conversational search engine that prioritizes accurate information retrieval with proper citations.

As we enter 2025, the demand for AI assistants continues to surge across professional, educational, and personal contexts. These tools have transitioned from novelty items to essential productivity aids, helping users with everything from research and coding to content creation and daily tasks.

This comparison is particularly relevant for diverse audiences: developers seeking coding assistance, content creators needing image generation, business professionals requiring accurate citations, and casual users valuing intuitive interfaces. By examining real user feedback across critical dimensions, we can determine which tool better serves specific needs and use cases.

Methodology

This comparison is based on an analysis of user reviews collected from major app platforms including the App Store and Google Play. These reviews were processed and labeled using a large language model (LLM) with a predefined dimension lexicon to ensure consistent categorization.

Each review was analyzed across three key metrics:

• dimension: The specific feature or aspect being evaluated (e.g., response speed, text quality)
• sentiment: Classification as positive, negative, or mixed based on the reviewer's tone and feedback
• keywords: Extraction of user-stated terms that highlight specific strengths or weaknesses

It's important to note that different tools may have varying volumes of reviews, which could influence the balance of feedback. Our analysis focuses on dimension-level insights, including positive/negative sentiment counts and emerging keyword trends, to provide a data-driven comparison of each tool's performance.

Dimension-by-Dimension Analysis

Citation Accuracy

Claude received 42.86% positive and 57.14% negative reviews for citation accuracy, with mentions of "accurate" alongside criticism like "false information" and "misleading info." Perplexity, however, had 74.81% positive, 16.3% negative, and 8.89% mixed reviews, with top keywords including "citations," "accurate," and "cites sources" highlighting its strength in source provision.

Citation accuracy is critical for users relying on verifiable information, such as students, researchers, and professionals, who need to trust that claims are backed by credible sources to avoid misinformation.
