Our verdict

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.

Best for: Android, Gmail, Drive and Docs users who want an AI assistant built into Google services

Skip it if: Privacy-focused users, given human review and possible training use while Keep Activity is on

Pros

  • A fairly complete free tier: image creation, Deep Research, Gemini Live, Canvas and Gems
  • Paid plans bundle large storage (400 GB, 5 TB), and Pro adds YouTube Premium Lite
  • AI Plus at $4.99/month is far cheaper than the category's usual ~$20 tier

Cons

  • Human reviewers may read a subset of chats, which Google keeps for up to three years even after you delete your activity
  • Trustpilot scores 1.4/5 from 1,456 reviews: users report made-up facts, forgotten context and unclear limits
All pros and cons · Who is it for?

Pros

  • Clear data controls: 3, 18 or 36 month auto-delete, an option to stop saving activity, and export via Takeout
  • Strong store ratings: 4.7/5 from over 2.4 million US App Store ratings and 1B+ Google Play downloads

Cons

  • The free tier runs on Flash-Lite; video creation, Pro models and Gemini 4 Argon need a paid plan, and Ultra costs $199.99/month

Best for

  • People who also need cloud storage and want AI bundled in the same plan (400 GB, 5 TB)
  • Eligible students: Google's page lists a free year of AI Plus or AI Pro discounted by up to 70%

Skip it if

  • People who want concrete usage numbers up front, since limits are only given as 2x, 4x, 5x or 20x multipliers

Experience & key features

What is Gemini?

Gemini is Google's AI assistant. It started as Bard, announced on 6 February 2023; on 8 February 2024 Bard and Duet AI were unified under the Gemini name, with an Android app and the Gemini Advanced plan. The iOS app arrived on the App Store in November 2024. It now runs on the web, iOS and Android, and the App Store description says it uses the Gemini 4 Argon and Gemini Omni models.

Key features

The free tier already includes image creation and editing, Deep Research, Gemini Live (voice chat with screen or camera sharing), Canvas and Gems. Paid plans add video creation, Google Flow credits (200 on Plus, 1,000 on Pro), Colab compute units (50 on Plus, 200 on Pro) and stronger models, with Gemini 4 Argon and Google Cloud credits from Pro up. The app also has a Daily Brief agent that summarises what you need to know each morning. Per Google's help center, limits refresh every 5 hours until a weekly cap is reached.

Pricing and value

The Vietnam subscriptions page prices plans in VND: AI Plus 132,000 ₫, AI Pro 489,000 ₫ and AI Ultra 2,250,000 ₫ (5x Pro) or 5,500,000 ₫ (20x Pro) a month, with cancellation anytime. The US App Store lists AI Plus at $4.99, AI Pro at $19.99 and AI Ultra at $199.99 (30 TB). The appeal is the bundled storage: 400 GB on Plus and 5 TB on Pro. Note that Google states each plan's limits only as multiples of the Free tier, not as concrete message counts.

More analysis

Who it's for and how it compares

Gemini fits best for people already using Gmail, Drive and Android who also need storage. ChatGPT has a broad toolset and a bigger user base, Claude is often chosen for long documents and coding, Perplexity leans toward cited search, and Microsoft Copilot is tied to Windows and Microsoft 365. Keep in mind that humans may review some chats, so check the Keep Activity setting before entering sensitive information.

Cancellation & refunds

The Vietnam subscriptions page says you can cancel anytime and that partial-period refunds are not given unless required by law.

Privacy

Per Gemini's privacy hub, human reviewers (including Google's trained service providers) read a subset of chats to improve services; those chats are disconnected from your account before reviewers see them. With Keep Activity on, activity auto-deletes after 18 months by default (3 or 36 months selectable) and may be used to train AI models; audio, Gemini Live video and screen shares are not used this way by default. Chats already seen by reviewers are kept for up to three years even if you delete your activity. With Keep Activity off, chats are still kept for 72 hours and are not used for training. Google's privacy policy (effective 16 Oct 2026) offers data export through Google Takeout and deletion in My Activity, and states that Google may use publicly available information to train its AI models.

Scores

Ease of use
8.2
Why this score

Available straight from a Google Account, with iOS/Android apps, 70 App Store languages and 4.7–4.8/5 App Store scores. Marked down because Trustpilot reviewers cite app crashes and forced installs, and model and plan names change often.

Features
8.6
Why this score

Chat, Deep Research, Gemini Live, Canvas, Gems, image and video creation, Google Flow, Google Workspace integration and a Daily Brief agent. Nearly as broad as ChatGPT, though many advanced features sit in Pro and Ultra.

Value for money
8.0
Why this score

AI Plus at $4.99 and AI Pro at $19.99 bundle 400 GB and 5 TB of storage, so value is high for people who need both. Ultra at $199.99 is expensive and limits are stated only as multipliers.

Performance
8.0
Why this score

Google ships models rapidly (Gemini 3 Pro on 18 Nov 2025, 3.1 Pro on 19 Feb 2026, Gemini 4 Argon in Oct 2026 per Wikipedia). No independent benchmark data was read, and Trustpilot reviewers report made-up facts and forgotten context.

Support
6.3
Why this score

A detailed help center and privacy guide exist. But no chat or phone channel for consumer plans appeared in the pages read, and some Trustpilot reviewers mention trouble with subscriptions and support.

Privacy & security
6.0
Why this score

Clear controls (auto-delete, Keep Activity off, Takeout) and a policy updated 16 Oct 2026. Marked down because humans review a subset of chats, reviewed data is kept up to three years, activity may be used for training while Keep Activity is on, and Google may use public information to train models.
