Now you're sitting there wondering which one to actually trust.

Head-to-Head Comparison
Ratings based on real-world job search tasks. 5 stars = best in class.
Which AI for Which Task?
- 📄 Writing or improving your CV → Claude or ChatGPT (Claude wins for detailed feedback)
- ✉️ Writing cover letters → Claude (most natural, least robotic-sounding output)
- 🎯 Interview preparation → Claude or ChatGPT (ask for mock questions + feedback)
- 🏢 Researching a company before interview → Perplexity or Grok (both cite sources)
- 💰 Salary research → Grok or Perplexity (real-time data)
- 📊 Job market trends → Grok (X/Twitter gives real-time industry pulse)
Are the Free Tiers Enough?
For most job seekers - yes. ChatGPT's free tier lets you write and refine CVs and cover letters. Claude's free tier handles solid document analysis. Gemini's free tier is the most generous of the bunch. Grok requires an X account but is otherwise free. The paid tiers are worth it if you're in an intensive search and hitting daily limits.
Use multiple tools for different tasks - don't pick just one. Use Claude for CV analysis, Perplexity for company research, and ChatGPT for brainstorming cover letter angles. All three have free tiers. The cost: $0.
