How the products differ

ChatGPT: ChatGPT suits anyone who wants one versatile AI assistant, with a usable free tier and paid plans from $8 to $500 a month. The trade-offs are possible ads on Free and Go in some markets, vaguely defined allowances, and a very low Trustpilot score (1.6/5) driven by billing and support complaints.

DeepSeek: DeepSeek suits people who want a free chatbot and developers who need a low-cost API with a 1M-token context. The trade-offs are data stored in China, a 2025 database exposure, and many support complaints on Trustpilot.

Choose around your use case

ChatGPT: Fits People who want one assistant for writing, study, research and coding in a single app; Users who want to start free and step up to Go, Plus or Pro as their needs grow. Strengths: Free offers unlimited text chats (with abuse guardrails) plus limited image creation, voice and deep research; Many price points: Go $8, Plus $19.99 and Pro from $100 a month, plus Business and Enterprise for organisations.

DeepSeek: Fits Developers who need a low-cost API compatible with OpenAI and Anthropic formats; Individuals who want a free chatbot for non-sensitive questions. Strengths: Free app, with no consumer subscription listed on the App Store; Low API prices, halved off-peak.

Costs and limits to check

ChatGPT: Go: 8 USD/month, as recorded in the review. Trade-off: Ads on Free and Go: tested in the US from January 2026, with visual ads next to image results since October 2026.

DeepSeek: Paid prices depend on plan and purchase channel; see the product review. Trade-off: Data is stored in China and used for model training. Prices retain the currency and billing units recorded in the source profiles; no currency conversion or plan equivalence is assumed. Check official prices, limits and terms before payment.

When to consider another option

ChatGPT is not aimed at: People who dislike ads on cheap plans: Free and Go may show ads, while Plus and above stay ad-free; Users who need predictable quotas: the pricing page describes allowances only as "limited" or "expanded", with no numbers.

Consider alternatives to DeepSeek if you are: Agencies and companies with strict data-residency rules; Users who want image generation or voice chat like rival chatbots' paid plans offer. Read these limitations alongside the feature table before deciding; a single strength cannot compensate for a missing requirement.
