Common Mistakes When Switching from Claude
1. Assuming All Chatbots Are the Same
Each AI has strengths and weaknesses. ChatGPT excels at reasoning, Gemini at multimodal tasks, Perplexity at research. Test multiple options before committing to a subscription.
2. Ignoring Free Tiers
Gemini Free is unlimited and surprisingly capable. ChatGPT Free and Perplexity Free are also generous. Try free tiers extensively before paying $20/month.
3. Not Using the Right Tool for the Task
Use Perplexity for research (citations), ChatGPT for coding (o1 models), Gemini for Google Workspace integration, DeepSeek for API cost savings. Multi-tool workflows often beat relying on one AI.
4. Overlooking API Costs
If you're building an app, API pricing varies wildly. DeepSeek is 10-50x cheaper than Claude or GPT-4. Compare per-token costs before locking into a provider.
5. Forgetting About Ecosystem Lock-In
