Best AI plan under $20
Originally published onCNET
ChatGPT Plus and Claude Pro are the standouts at $20. If you need search, try Perplexity Pro. For free-tier power, DeepSeek is hard to beat.
ChatGPT Plus offers the best all-rounder experience. Claude Pro wins for writing and coding. Perplexity Pro is best for research and citations.
Free alternatives such as DeepSeek V4, Gemini free tier, and Microsoft Copilot free give you strong models without paying, though with lower limits and fewer features.
