The Smart Free Strategy

You don't need to pick just one. Here's how I'd use free AI without spending anything:

1. Daily assistant → Google Gemini (real-time info, no limits)
2. Coding/math → DeepSeek (strongest reasoning)
3. Important writing → Claude free (best quality, save for when you need it)
4. Research → Perplexity (sourced answers)
5. Everything else → ChatGPT free (versatile)

By combining free tiers strategically, you get 90% of the paid experience at $0/month.

When to Upgrade to Paid

The free tier becomes limiting when:

• You hit Claude's message limits multiple times daily
• You need unlimited GPT-4o access
• You research heavily (Perplexity Pro removes limits)
• You code professionally (Cursor/Copilot are worth it)
• You need consistent, reliable access without throttling

For most casual users? The free tiers in 2026 are genuinely sufficient.
