AI tools have added a new category to subscription stacks that did not exist 3 years ago. Many professionals now pay for more than one AI subscription, often with overlapping capabilities.
The Current Landscape
Large Language Models: - ChatGPT Plus: general assistant with image generation and data analysis - Claude Pro: general assistant, strong on long documents and writing - Google AI Pro (formerly Gemini Advanced): Gemini inside Google apps, bundled with storage - Perplexity Pro: web search with cited AI answers
Image Generation: - Midjourney: dedicated image generation - Adobe Firefly (included in Creative Cloud): Commercially safe images - DALL-E (included in ChatGPT Plus)
The Overlap Problem
ChatGPT Plus and Claude Pro serve similar use cases for most users. Perplexity Pro overlaps with both for research tasks. Most people do not need more than one premium LLM subscription.
The Rational Decision Framework
If you use AI primarily for writing and analysis: Pick one of ChatGPT Plus or Claude Pro. Try each on your actual work tasks for one month, then decide which produces better results for your specific use case.
If you use AI primarily for research: Perplexity Pro's web integration makes it the strongest choice.
If you use AI for code: GitHub Copilot is more specialised and cost-effective than general LLMs for programming.
If you use AI for images: Midjourney's quality is unmatched for creative work. Adobe Firefly is the choice for commercial use without copyright concerns.
The Review Cycle
AI tools evolve rapidly. What is best today may not be best in 6 months. Review your AI subscriptions quarterly — this category changes faster than any other.
