ChatGPT vs Claude vs Gemini: which AI assistant should you use?

Choose ChatGPT if you want the widest set of features in one app, Claude if you mostly write, work with long documents or code, and Gemini if you live in Google's apps or want the most storage and value in a bundle. All three are excellent general AI assistants with free plans and a standard paid plan of about $20 a month, so the best way to decide is to test each on the same three tasks from your week.

The three apps copy each other's features quickly, and their models change every few months. This comparison focuses on the differences that tend to last: what each is built around, where it fits into your day and how it treats your data. Prices and models were checked on the makers' pages in November 2026.

The short answer

Prices are US prices and vary by country, so check each maker's pricing page before you buy.

ChatGPT: the all-rounder

ChatGPT is the most widely used AI assistant and has the broadest feature list. One app covers chat, image creation, voice conversations, file analysis, deep research, custom GPTs, scheduled tasks, an agent that can work in a browser and Codex for coding.

Strengths

• The widest range of tools in one place, so it's a safe default if you want one subscription
• Strong image creation and natural voice mode
• Memory that remembers your preferences across chats
• A huge ecosystem of custom GPTs, tutorials and integrations

Weaknesses

• So many features and models can be confusing, and plans differ a lot in what they include
• The free plan and the low-cost Go plan may show ads
• Chats are used for training by default on personal plans unless you turn it off

Plans: Free, Go (low cost), Plus ($20 a month) and Pro (from $100 a month), plus Business and Enterprise plans for teams.

Claude: the writer and coder

Claude is known for clear, natural writing, careful reasoning and handling long documents well. It's a favourite of writers, analysts and developers.

Strengths

• Writing that tends to sound less generic and follows style instructions closely
• Good at reading and comparing long reports, contracts and codebases
• Artifacts, which turn answers into documents, slides, dashboards and small apps you can view and share
• Claude Code, a coding agent that works in your terminal and editor, included from the Pro plan
• Projects, which keep files and instructions together for ongoing work

Weaknesses

• Fewer media features: it doesn't make videos, and image work is more limited than ChatGPT's or Gemini's
• Usage limits on busy plans can be reached quickly with long documents
• No plan cheaper than Pro

Plans: Free (Sonnet and Haiku models), Pro ($20 a month, or $17 a month billed yearly, adds Opus and Claude Code), Max ($100) and Ultra ($200) for heavy use, and Team from $25 per seat a month.

Gemini: the Google one

Gemini is Google's assistant, built into Gmail, Docs, Sheets, Drive, Android and Chrome. If your work already lives in Google's apps, it saves the most copying and pasting.

Strengths

• Works inside Google apps: summarise an email thread, draft in Docs, find a file in Drive
• A very large context window (1 million tokens on Google AI Pro), handy for huge documents
• Strong media tools, including Veo for video and Nano Banana for image editing
• Paid plans bundle cloud storage (5 TB on Google AI Pro) and other Google extras, which makes them good value if you'd pay for storage anyway
• A low-cost Google AI Plus tier

Weaknesses

• Works best if you use Google's apps. Less useful if you're on Microsoft 365
• Plan names and features change often and are bundled with other Google services, which makes them harder to compare
• Chats are used to improve Google's AI while "Keep Activity" is on, and some are read by human reviewers

Plans: Free, Google AI Plus, Google AI Pro (about $20 a month, with Gemini 4 Argon and Gemini 3.1 Pro) and Google AI Ultra for the highest limits.

Head-to-head by task

Each maker ships several models and swaps them often. At the time of writing, the top models were GPT-6.1 Sol in ChatGPT, the Opus family in Claude and Gemini 4 Argon in Gemini. Rather than chasing model names, compare the apps on your own tasks. Many of these assistants also offer reasoning models that think longer before answering, which helps with maths, planning and tricky analysis.

Privacy compared

All three let you limit how your chats are used, but the defaults differ on personal plans:

• ChatGPT: chats can be used to train models by default. Turn off Improve the model for everyone in Settings → Data controls. Temporary Chats are deleted after 30 days and aren't used for training.
• Claude: you choose whether chats are used, through the Model Improvement setting in Privacy Settings. If you allow it, data is kept for up to five years; if not, the standard 30-day period applies. Incognito chats are never used for training.
• Gemini: chats are used to improve Google's AI while Keep Activity is on, and a sample is reviewed by people. Turn it off in Gemini Apps Activity; chats are then kept for 72 hours.

Business and enterprise plans from all three exclude your data from training by default. For more ways to protect yourself, read our AI privacy tips.

Which should you choose?

• You want one app that does everything: ChatGPT.
• You write for a living, or work with long documents: Claude.
• You're a developer: Claude or ChatGPT, then try both coding agents on your own repository.
• Your work lives in Gmail, Docs and Drive: Gemini.
• You're on a tight budget: start with the free plans, then try ChatGPT Go or Google AI Plus.
• You can't decide: use the free plans of all three for a week on the same tasks, and follow our checklist for choosing an AI tool.

Many people end up paying for one and keeping a second on the free plan for a second opinion.

The bottom line

There's no single winner. ChatGPT is the most complete all-rounder, Claude is the strongest pick for writing, long documents and coding, and Gemini is the natural choice for Google users and the best value bundle. All three are close enough that the right answer depends on your work, so test them on your own tasks before paying. Compare more AI chatbots in the directory.

Frequently asked questions

Which is better, ChatGPT or Claude?

ChatGPT has more features, including image creation and voice, so it suits most people as an all-rounder. Claude is often preferred for writing quality, long documents and coding. Both cost $20 a month for the standard plan, so try both on your own work.

Is Gemini better than ChatGPT?

Gemini is better if you use Gmail, Docs and Drive, since it works inside them, and its paid plans include a lot of cloud storage. ChatGPT has a broader set of standalone features. For general questions, both are excellent.
