Pick by job, not by brand

Writing, documents, research, coding, chat: for each job, the plan to start with and the runner-up if it disappoints. One table, one decision.

In this lesson you will

Match your main job to a recommended $20 plan and a runner-up
Know the one question that separates ChatGPT Plus from Claude Pro
Avoid the two most common mis-picks

People pick a brand and then find jobs for it. Do it the other way round: name the job you would do most in the first week, then pick. The table gives a first choice and a runner-up for each; the runner-up exists because a plan that looks right on paper sometimes does not fit your hands, and a $20 experiment is cheap.

Pick the row that matches the job you will do most. All plans $20 (Google AI Pro $19.99) as of 2026-09-12.
Your main job	Start with	Why	Runner-up
Writing (emails, articles, anything you edit)	Claude Pro	Strongest at tone and long-form; projects keep your style notes between sessions	ChatGPT Plus
Documents (reading, summarising, comparing files)	Claude Pro	Longest working context; handles a stack of PDFs in one conversation	Google AI Pro, if the files live in Drive
Research (find sources, check facts, stay current)	Perplexity Pro	Live web search with citations on every answer	ChatGPT Plus with search on
Coding (writing and fixing code in a real project)	Cursor Pro	An editor, not a chat window: it sees your files and edits them in place	Claude Pro or ChatGPT Plus for explanations and snippets
Chat (everyday questions, planning, images, voice)	ChatGPT Plus	Broadest feature set and the most forgiving caps for a stream of short messages	Google AI Pro, if you already live in Gmail and Docs

The ChatGPT Plus versus Claude Pro question

This is the comparison most people are really asking about, and it comes down to one question: is your work mostly text you will edit, or mostly everything else? Text you will edit (drafts, documents, long reads) favours Claude Pro. Everything else (images, voice, quick lookups, a hundred small tasks a day) favours ChatGPT Plus. The full comparison is at ChatGPT vs Claude; the one-question version gets most people to the same place.

My main job in week one is [JOB]. I will start with [PLAN] because [REASON]. If it disappoints on [WHAT WOULD DISAPPOINT], I will switch to [RUNNER-UP] before the second month.

Hint: Writing the disappointment condition down now is what makes lesson 4's cancel-and-switch painless later.

Lesson FAQ

ChatGPT Plus or Claude Pro for writing?

Claude Pro is the usual first choice for writing and long documents: it holds more context, keeps style notes in projects, and tends to edit rather than rewrite. ChatGPT Plus is the runner-up and wins if your writing work also needs images, voice or a lot of quick lookups.

Is Cursor Pro a chatbot?

No. Cursor is a code editor with AI built in; it reads and edits the files in your project. If you want to ask questions about code, a chat plan is fine. If you want the code changed, Cursor is the tool the price is for.

Can one $20 plan cover everything?

For most individuals, yes, with free tiers as backups for the occasional other job. Two paid plans are justified only when you do two of the table's jobs heavily every week.

What about Google AI Pro at $19.99?

It is the plan for people whose work already lives in Gmail, Docs and Drive; Gemini appears inside those apps and the bundle includes NotebookLM and storage. As a standalone chatbot it is the runner-up rather than the first pick for most jobs.
