ChatGPT, Gemini and Claude all charge 20 dollars a month for their standard paid plan, so price will not decide this for you; fit will. ChatGPT bundles agent mode, custom GPTs and Codex, Gemini bundles Google storage and media credits, and Claude bundles Claude Code, Projects and Microsoft 365 integration, according to each vendor’s own pages.
We have not run hands-on benchmarks, so this guide does not claim which assistant writes, reasons or codes best. Model quality changes with every release, and the honest way to choose is to test on your own work. What we can do is compare what the vendors publish about plans, features and data handling, as of 31 October 2026. For the method, see how to choose the right AI tool for your workflow, and for prices in detail, AI tools pricing compared.
The Side-by-Side Table
| Factor | ChatGPT (OpenAI) | Gemini (Google) | Claude (Anthropic) |
|---|---|---|---|
| Free plan | Yes; limited access | Free Gemini app (plan page did not detail it) | Yes; limited usage every 5 hours and weekly; Sonnet and Haiku only |
| Standard paid | Plus: 20 dollars a month | Google AI Pro: 20 dollars a month | Pro: 20 dollars a month, or 200 dollars billed upfront a year |
| Heavy-use tiers | Pro: 100, 200 and 500 dollars (third-party report) | AI Ultra from 100 dollars; 200 dollar tier adds Project Genie | Max: 100 dollars; Ultra: 200 dollars |
| Models named on plans page | GPT-5.5 Instant, Thinking and Pro | Gemini 4 Argon, 3.1 Pro, 3.6 Flash | Sonnet, Haiku, Opus; Fable via usage credits |
| Research mode | Deep research | Deep Research | Research on Pro |
| Coding agent | Codex | Not named on the plans page we read | Claude Code on Pro |
| Bundled extras | Agent mode, projects, tasks, custom GPTs | 5 TB storage, 1 million token context, media and cloud credits on AI Pro | Projects, Claude in Chrome, Microsoft 365, task scheduling |
| Team plan | Business (third-party: 20 dollars annual per user) | Not covered here | Team Standard: 25 dollars monthly, 20 annual per seat |
Prices are in US dollars and exclude tax. The ChatGPT and Google official pages showed no numeric prices when we fetched them, so those figures come from OpenAI’s January 2026 statement relayed by Daring Fireball, a third-party October 2026 post and Engadget. Claude’s numbers come from its own page. All can change.
How Do Privacy Settings Compare?
| Vendor | What it says | Source |
|---|---|---|
| OpenAI | Turning off ‘Improve the model for everyone’ means new conversations are not used for training; Temporary Chats are deleted within 30 days | OpenAI Help Center |
| A subset of chats are reviewed by human reviewers; keep confidential information out; turn off Keep Activity to stop future review; reviewed chats kept up to three years | Gemini Apps Privacy Hub, dated 26 October 2026 | |
| Anthropic | Free, Pro and Max users choose whether chats train models; five-year retention if opted in, 30 days if not | Anthropic, 28 August 2025 |

Who Should Pick ChatGPT?
Consider ChatGPT if you want one product that lists chat, deep research, agent mode, custom GPTs and Codex, and you like trying new features early, since its page mentions early feature access on Plus. Note that OpenAI said in January 2026 that it planned to test ads in its free tier and ChatGPT Go in the US, as covered in our ChatGPT ads explainer.
Who Should Pick Gemini?
Consider Gemini if you live in Google’s apps or want cloud storage in the same bill. Google AI Pro lists 5 TB of storage, a 1 million token context window and monthly credits for media tools. The Ultra plan was cut to 100 dollars a month in May 2026, according to Engadget.
Who Should Pick Claude?
Consider Claude if you want a coding agent and long-document work alongside Microsoft 365, since Pro lists Claude Code, Projects, Research and Claude for Microsoft 365. Free users get Sonnet and Haiku models only. Anthropic’s consumer data choice does not apply to Commercial Terms services such as Team and Enterprise.
A Decision Table for Real Situations
| Situation (ours) | Start with | Why |
|---|---|---|
| You are on a tight budget | Free plans of all three | Compare before paying |
| You use Google Workspace daily | Gemini | Same ecosystem and storage |
| You use Microsoft 365 daily | Claude or a Microsoft tool | Claude lists a Microsoft 365 integration |
| You want to try agents and custom assistants | ChatGPT | Agent mode and custom GPTs listed |
| You write code daily | Test Codex and Claude Code | Each lists a coding agent |
| You handle sensitive data | Business plans with written terms | Data terms differ by plan |

What Do the Free Plans Mean for Your Choice?
The simplest route is to open all three free options, give them the same real task and compare the time you spend fixing each result. Because free limits and models change, repeat the test every few months.
