→ Free users who mostly chat will hit fewer walls on ChatGPT thanks to unlimited text chat, at the cost of possible ads.
Top-tier pricing[1],[3],[17]Pro 100 ($100), Pro 200 ($200), Pro 500 ($500) per month; unlimited image creation, context up to 400KGoogle AI Ultra: $199.99/month (30 TB), two tiers at 5x or 20x Pro limits
→ In the US, ChatGPT's $100 Pro tier is a lower entry point than Gemini Ultra's $199.99, but in Vietnam the Ultra 5x tier (2,250,000 VND) costs less than Pro 100 (2,849,000 VND), so the cheaper option depends on your market.
Bundled cloud storage[12],[13]No public information found15 GB (Free), 400 GB (AI Plus), 5 TB (AI Pro), 30 TB (Ultra); Pro adds YouTube Premium Lite
→ Anyone already paying for Google storage should weigh Gemini, since it can merge AI and storage into one plan, though the research did not cover ChatGPT on this point.
Platforms[3],[5],[18]Web, iOS, Android, Windows, macOSWeb, iOS, Android
→ Desktop-heavy users get native Windows and macOS apps with ChatGPT, while Gemini is browser-only on computers.
Integrations[1],[12],[13]Codex, Deep research, Custom GPTs, Epic (ChatGPT Health)Gmail, Google Drive, Google Docs, Google Photos, YouTube, Google Colab, Google Flow

→ ChatGPT scores slightly higher on both stores and Trustpilot, but both have low Trustpilot scores, so expect billing and support friction either way.
Refund policy[1],[12]OpenAI's terms could not be read; App Store purchases are refunded under Apple's policyCancel anytime; no partial-period refunds unless required by law
→ Check refund terms yourself before buying a costly plan on either service, as neither offers a clear refund promise.

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.

Gemini: Gemini suits people already living in Google's ecosystem, since paid plans bundle 400 GB to 30 TB of storage and there is a cheap $4.99/month tier. The downsides are usage limits expressed as hard-to-picture multipliers, human review of some chats, and a Trustpilot score of just 1.4/5.
