Which AI Assistant Is Best? ChatGPT vs. Perplexity vs. Claude vs. Gemini vs. DeepSeek

Choosing the right AI assistant for your business can save you hours and amplify your productivity—**but not all models are created equal. Depending on what you’re trying to do (research, writing, coding, summarising, etc.), one might be a better fit than another.

Here’s a breakdown of the top 5 contenders and what they do best in 2025.

🧠 ChatGPT: The All-Rounder for Everyday Business Tasks

Best for: writing emails, blog posts, building prompt workflows, and content repurposing

Suppose you need a co-pilot for content, strategy, or automations. In that case, ChatGPT remains your best bet—especially the GPT-4 model, with its faster output, image understanding, and plug-in integrations (such as a code interpreter or Canva).

  • ✏️ Blog writing, captions, summaries

  • 📅 Marketing planning & workflows

  • 📊 Reporting with AI tools and spreadsheets

  • 🔗 Integrations with tools like Zapier, Mailchimp, and Google Drive

SBPS Verdict: If you’re running a business and want a flexible, friendly AI that helps you do your job better, start here.

🔎 Perplexity: The Research Powerhouse

Best for: real-time information, fact-checking, quick overviews

Perplexity is like ChatGPT, but with a built-in search engine. It shines when you need live, up-to-date answers with sources—great for making quick decisions, planning content, or conducting competitive research.

  • ✅ Cites every source

  • 🌐 Great for exploring new trends or questions

  • ⚡ Lightning fast

SBPS Verdict: Use Perplexity when you need trustworthy data, not just a helpful answer.

🧩 Claude: The Empathetic Long-Form Assistant

  • 🧠 Handles 100,000+ tokens (huge files!)

  • ✨ More nuanced, conversational tone

  • 🤝 Ideal for people-focused industries

SBPS Verdict: Use Claude when clarity, tone, and context matter most—great for comms, HR, or client docs.

🌐 Gemini: The Google-Connected Assistant

  • 👨‍💻 Great for Python, SQL, web scraping

  • 🌏 Supports multiple languages

  • 💡 Excellent for open-source projects

SBPS Verdict: Not for everyone, but a strong tool if you’re in a technical field.
