I asked ChatGPT, Gemini, Claude and Perplexity what they think of each other - Tom's Guide

What the report says

Tom’s Guide reported on an informal comparison of four widely used AI assistants — OpenAI’s ChatGPT, Google’s Gemini, Anthropic’s Claude and Perplexity — by asking each tool for its “honest” view of the others. The article, written from the perspective of a regular user of all four products, frames the exercise as a way to surface how the chatbots describe rival strengths and limitations rather than as a controlled benchmark.

According to Tom’s Guide, ChatGPT characterized Gemini as useful for research because of Google’s information ecosystem, Claude as a strong natural-language writer, and Perplexity as a trustworthy AI search tool because it exposes sources. It also cautioned that Gemini can be broad rather than deep, Claude can be overly cautious or wordy, and Perplexity may be less suited to long collaborative work.

Gemini’s response reportedly presented ChatGPT as a versatile general-purpose assistant with a broad product ecosystem, Claude as a strong option for long documents, nuanced reasoning and polished prose, and Perplexity as primarily an AI-powered research engine built around web retrieval and citations. When prompted for weaknesses, Gemini pointed to tradeoffs including ChatGPT’s fact-checking limits, Claude’s safety and real-time tool constraints, and Perplexity’s weaker performance when used like a traditional conversational chatbot.

Tom’s Guide said Claude began by noting its own lack of neutrality as an Anthropic product, then described ChatGPT as the market leader, Gemini as advantaged by Google Search and Workspace integration, and the broader AI market as rapidly shifting. The piece matters as consumer AI tools increasingly overlap, making task-specific choice — writing, research, coding, workflow integration or source-backed search — more important than naming a single best chatbot.
