Should I use ChatGPT or Claude for everyday work?

For most office work either one does the job, and the choice comes down to four rows in the table below: images, connectors on the free plan, very long documents and the Word or Excel add-in. I use Claude for most of my own work and keep ChatGPT for images and because my clients use it. Every product fact and price on this page comes from the vendor pages I opened on 19 October 2026, and where a page gave no number I say so instead of guessing. This is the job-by-job comparison under the learning path without coding.

Which one should I pick if I can only pay for one?

Pick by the jobs you do every week, using the job table in the next section, because for writing, summarising and quick questions the two products overlap almost completely.

Prices first, since one subscription budget is the constraint. OpenAI's pricing page at chatgpt.com/pricing prints no currency amounts; each plan shows only "/ month". The ChatGPT figures below come from OpenAI's help centre instead. Anthropic's pricing page prints its amounts.

Plan	ChatGPT	Claude
Free	Free. The help centre says "ChatGPT is free to use". Default model: GPT-5.6 Luna	$0. Current models: Fable 5.1, Opus 5.5, Sonnet 5.5, Haiku 5.5. Fable is paid only
Entry paid	Go: no price printed on the Go help page or the pricing page. Plus: "$20/month (billed monthly)" per the Plus help page. Model on Plus: GPT-6 Sol	Pro: $20 a month billed monthly, or $17 a month billed annually ($200 up front)
Top tier	Pro $100 or Pro $200 (Pro 20x) per the Pro help page. Models on Pro: GPT-6 Pro and GPT-6 Astra	Max: $100 a month for 5x Pro usage or $200 a month for 20x, per the Max help page. The pages I opened give Max as a monthly figure only

Go has no printed price. The Go help page says "Subscription prices can be found in the ChatGPT pricing page", and that page prints no number. If Go is the plan you want, open chatgpt.com/pricing on the day you decide.

Gemini is out of scope here; the hub guide has one line on where it fits.

One disclosure before the verdicts. AI Academy is my course, so weigh my picks with that in mind.

What does each one do job by job?

The table has one row per everyday job. Each cell records what the vendor's page said and on which plan, and the last column is my pick, where "either" means the pages gave me no reason to prefer one. The hub's table covers three tools at one line each; this one goes deeper on the two.

What each vendor's page said when I opened it on 19 October 2026. "Not stated" means the page gave no figure. Plan and model names are as the pages print them.

One row has a conflict. Anthropic's pricing page lists "Projects" under Pro, while its help page says projects are available to all users with "a maximum of five projects" on Free. I went with the help page, which carried an "Updated this week" stamp.

Where is ChatGPT the better pick?

ChatGPT is the pick for images, for voice with a stated number of hours, and for a free plan that reaches further into Word, scheduled tasks and coding. Those are the rows where OpenAI's pages state something Anthropic's pages list as paid or not at all.

Images is the clean win. OpenAI's help page names the model as "ChatGPT Images 2.5" and says "ChatGPT Images is available on all tiers". Anthropic's page says Claude "doesn't generate photos or illustrations the way image-generation tools do"; it builds diagrams and charts in HTML and SVG, which covers a bar chart from a spreadsheet and does not cover a social post graphic. If one job on your list is "make a picture", you need ChatGPT.

Voice is a win on paid tiers because OpenAI prints hours and Anthropic does not. The voice FAQ gives Go and Plus 3 hours in a rolling 24-hour window, Pro $100 15 hours, and Pro $200 unlimited "subject to abuse guardrails". Claude's page says voice mode is a beta "available to all plans" and that "Voice conversations count toward your regular usage limits". No hour figure. If you dictate for an hour a day, only OpenAI has told you how many hours you get.

The free plan reaches further on three add-ons. ChatGPT for Word is "available on all ChatGPT plans, including Free". Scheduled tasks give Free and Go 3 active tasks, Plus 5 and Pro 15. Codex is "included across ChatGPT plans, including Free and Go". On Claude the same three sit behind a paid plan: Excel on Pro, Max, Team and Enterprise per the docs page, scheduled tasks on "all paid plans", Claude Code on "Pro or Max".

Where is Claude the better pick?

Claude is the pick for connectors on the free plan, long documents, projects on the free plan, a citation on every web search and file creation, and on a paid plan it adds Excel and a browser extension. These are the rows where Anthropic's pages state a figure or "all users" and OpenAI's say "depends on your plan".

Connectors come first because they change what the assistant can see. Anthropic's Google Workspace page says the Gmail, Google Calendar and Google Drive connectors are "available for all users on Claude and Claude Desktop". OpenAI's apps page links setup pages for Google Drive, Outlook, Slack, Notion and others, lists Gmail only as an event trigger, and says "App availability depends on the app, your ChatGPT plan, region, workspace, role, model". The plumbing behind both is MCP, and the MCP guide covers how to switch a connector on and what to let it do.

Long documents are the second reason. Claude's context window page lists Fable 5.1, Opus 5.5, Sonnet 5.5 and Haiku 5.5 at 1M tokens on paid plans and describes 200K+ tokens as "about 500 pages of text or more". OpenAI's models page gives no context window figure. On uploads, Claude's page caps a PDF at 1,000 pages with no plan differences, while OpenAI's says "Free users are limited to 3 file uploads per day". Projects follow the same pattern: up to five on Claude's free plan, and 5 files per project on ChatGPT's.

Citations and files are the third. Claude's web search page says "Every response includes citations, so you can easily verify sources yourself"; OpenAI's says responses "may include citations". For a person who checks sources, that "may" costs time. The checking routine itself is in spotting an AI hallucination in five minutes. On files, Claude's page says code execution and file creation are enabled by default on Free, Pro and Max, with Excel files "with working formulas"; OpenAI's data analysis page says availability "can vary by model, plan, workspace settings, and account capabilities". On paid plans Claude adds Excel and Chrome, and the Chrome page itself calls the extension "still risky", so read that page before you switch it on.

My own setup is the worked example. I run most of my work in Claude because of projects, skills and connectors: a project holds the files and instructions for each piece of work, Google Ads and Meta run through MCP connectors so I can ask for a performance pull in plain language, and skills hold my writing rules. I keep ChatGPT for image generation and because my clients use it and I need to see what they see. I pay for both, which you do not need to do in your first month.

How do the usage limits compare?

ChatGPT puts a separate cap on each tool. Claude runs one cap over everything, in time windows. Neither vendor prints a number of messages, so the comparison is in the shape of the limits.

OpenAI's Free tier FAQ says "Free users have unlimited everyday text chats, subject to abuse-prevention safeguards", and that "File uploads, image generation, voice, data analysis, and other tools have separate usage limits". The Go page says "Free and Go users both have unlimited everyday text chats". Plus "may include usage limits such as message caps, especially during high demand". The Pro page gives Pro $100 as "5x higher usage than Plus" and Pro $200 as "the highest usage tier".

Anthropic's pricing FAQ says "there's no fixed message count", limits "reset on a rolling five-hour session window", and "paid plans add weekly limits on top". The Max page says Max 5x "includes five times the Pro plan's per-session usage allowance" and Max 20x twenty times. Research "can use up your limits faster", voice counts toward the same limits, and Claude Code shares them with chat. The Fable page says that on Pro the Fable models "aren't included in your plan's usage limits" and that on Max you can spend "up to 50% of your weekly usage limits on Fable".

In practice, for someone writing emails and summarising documents on a free plan, the ChatGPT limit you meet first is the 3 uploads a day, and the Claude limit you meet first is the five-hour window on a heavy afternoon. I can't tell you how many messages that is, because neither page does. Keep a tally in your first month.

What I'd do in the first month

1. Pick one free plan and stay on it for a month. Switching before you can brief one well only teaches you two sets of menus.
2. Run one test task per row in week one, with the answer known before you start: a document you wrote, a PDF you have read, a spreadsheet you can check, a question whose source you know.
3. Set the training toggle on day one. ChatGPT: Settings > Data controls, "Improve the model for everyone". Claude: Settings > Privacy, "Help Improve our AI models". Claude's page does not state the default, so look rather than assume.
4. Write down every time you hit a limit: which tool, which job, what time. After four weeks you'll know whether the cap you hit is uploads, hours or the session window.
5. Pay when a row in the table names a paid plan for a job you do every week. On Claude, Pro at $20 a month adds Research, Claude for Excel, Claude in Chrome and the 1M token context the help page lists for paid plans. On ChatGPT, Plus at "$20/month (billed monthly)" adds the 3 voice hours, 25 files per project and 5 scheduled tasks.
6. Add the second tool only for a job the first cannot do. The pair that justifies two subscriptions is images plus long documents. The other reason is a client or an employer who has already chosen.

The tool map module walks through the job table above with screenshots and carries a dated review note so you know when it was last checked against the live product. The Claude essentials module covers projects, memory, connectors and file creation in Claude, one screen at a time. Both sit in the beginner volume of the course, which is mapped in How do I learn AI without coding and get from chat user to operator?
