The average knowledge worker now subscribes to 4.2 AI tools. Most of them overlap by 60%. Here is how to stop the subscription creep and build a lean, powerful AI stack.
Core layer ($20/month) — Claude Pro: Use it as your primary thinking partner. Long-form writing, document analysis, coding help, and research. The 200K context window is a game-changer for complex projects.
Image layer ($10/month) — Midjourney Basic: 200 images/month is enough for most freelancers. Upgrade to Standard ($30) only when you need unlimited generations.
Code layer (free) — GitHub Copilot Free Tier: The free tier now includes 2000 completions/month and 50 chat messages. Sufficient for part-time developers.
Search layer (free) — Perplexity Free: For research that requires up-to-date web sources. The free tier covers most use cases.
Total: $30-50/month depending on usage. Cancel your separate SEO, copywriting, and image editing AI subscriptions — Claude handles 80% of those tasks.
