Update for Research Model Comparisons:

————–

I keep reading about the differences of multiple AI chatbots and their endless fast-paced updates. I compiled a list of articles on this topic. I wanted to create a concise and easy-to-understand comparison of these tools. With the help of ChatGPT, I created the table below for comparing these top chatbots or general purpose AI tools.

This guide makes it easy to compare them and find the best fit for you.

Feature Breakdown for the AI Chatbots

💡 ChatGPT – Best for Versatility & Creativity
✅ Great for writing, coding, and brainstorming.
❌ No source citations, sometimes inaccurate.

💡 Claude – Best for Business & Structured Tasks
✅ Ethical, well-organized, ideal for work and writing.
❌ No web browsing, fewer integrations.

💡 Perplexity – Best for Research & Fact-Checking
✅ Cites sources, ideal for deep research.
❌ Less creative, not great for storytelling.

💡 Gemini – Best for Google Users & Technical Work
✅ Seamless Google Workspace integration, long memory.
❌ Less intuitive than ChatGPT.

💡 Microsoft Copilot – Best for Office & Excel
✅ Works well with Microsoft 365 apps.
❌ Can be unpredictable outside of MS tools.

💡 DeepSeek – Best Free AI for Logical Thinking
✅ Transparent reasoning, completely free.
❌ Privacy concerns, not widely tested.

Final Breakdown based on your Purpose

• For casual, general-purpose use: ChatGPT
• For professional writing & structured tasks: Claude
• For research & citations: Perplexity AI
• For enterprise & office tasks: Microsoft Copilot
• For Google users & integration: Gemini
• For logical problem-solving: DeepSeek

I hope the above is a practical and simple guideline for picking the best chatbot that best fits your work!

Update (May 2025): I read this article “ChatGPT vs Gemini vs Perplexity vs Claude : Which AI Assistant is Best?” by GeekyGadgets and visualized their comparison below:

Notes/Updates:

1. Claude’s differentiation on safety: Detecting and Countering Malicious Uses of Claude by Anthropic: Anthropic is committed to preventing misuse of its Claude models by adversarial actors while maintaining their utility. Some actors have misused the models, including an influence-as-a-service operation, credential stuffing, recruitment fraud, and a novice actor using AI to enhance malware generation. Anthropic has taken steps to detect and counter such misuse, including banning accounts and improving detection methods.
2. Perplexity offers an open-sourced, uncensored version of Deepseek. “Perplexity open-sourced the model weights for R1 1776, an uncensored version of R1 that the company says “has been post-trained to provide unbiased, accurate, and factual information,” according to the announcement. Perplexity notes that its decensoring training process did not negatively impact other parts of the model’s performance, including math and reasoning.” Read more here.
3. Enterprises that cannot afford any hallucinations can consult to AI assistants claiming higher accuracy, such as Contextual AI. It is an AI assistant based on a grounded language model (GLM) developed using retrieval-augmented generation (RAG). General-purpose models such as ChatGPT or Claude, are built for a wide range of tasks from creative writing to technical documentation. However, Contextual AI specializes in high-stakes enterprise environments where accuracy is critical. Read more here.
4. Claude is said to be better than ChatGPT in several areas; mainly creative writing and providing more features for free users. The article linked below suggests Claude is better than ChatGPT on these four dimensions: Creative Writing; Offers Multimodality for Free; Larger Context Window; and More Messages Per Hour. Read more here.
5. Anthropic is the parent company of Claude AI. They also have the Console portal. “Claude” refers to the AI model itself, a large language model capable of generating human-like text. “Anthropic Console” is a developer platform that provides tools to build prompts and interact with the Claude model. It essentially acts as a control panel for accessing and customizing Claude’s capabilities through an API interface. You can think of Claude as the AI assistant and the Console as the developer workbench to fine-tune its functionality. Read more here.
