How to run a solo strategy sprint with an AI assistant.

Claude vs ChatGPT for a solo sprint

Claude plan facts read on the vendor's public pricing page on 9 November 2026 in US dollars. ChatGPT plan details not confirmed; see the vendor page. The Good for in a sprint row is a suggestion to test, not a result.

Which one should you pick?

What is an AI assistant good for in a sprint?

Think of it as a well-read colleague who never gets tired and has never met your customers. That second part matters. It can organize, question and rephrase. It cannot know why your best client stayed for six years.

Simple-Growth uses Claude for some of its own work, so weigh that when you read the comparison below. The method works with any assistant, and the best result comes from your evidence plus its structure, not from its guesses.

Good jobs for it: sorting messy notes into themes, asking awkward questions, drafting alternative wordings, and playing a doubtful buyer. Poor jobs: deciding your strategy, supplying facts about your market, or writing the final version without your edit.

What should you feed it first?

Picture this: you open a blank chat, type "write me a strategy" and get three polished paragraphs that could describe any business on earth. That is the cost of giving it nothing to work with.

Give it raw material instead:

• Customer words: reviews, emails and quotes, trimmed of names.
• Your reasons for wins and losses, in a short list.
• A plain description of your business, who you serve and what you sell.
• Your constraints: team size, budget range, deadlines, things you will not do.
• The decision you are trying to make this week.

Say clearly that you want it to use only what you provided and to flag anything it is assuming.

Which prompts are worth using?

Here are plain examples you can paste and adapt. Replace the brackets with your own details.

• Pattern finder: "Here are 15 customer comments about why they chose us. Group them into themes and tell me which theme appears most. Quote the lines that support each theme."
• Doubtful buyer: "Act as a skeptical buyer in [my industry]. Here is my draft positioning sentence: [sentence]. Tell me what you do not believe and what proof you would want."
• Competitor swap test: "Rewrite this sentence as if a competitor said it. Tell me whether it still works. If it does, what makes it too generic?"
• Three shapes: "Give me three alternative wordings of this idea: one problem-first, one method-first, one result-first. Keep each under 25 words."
• Gap hunter: "What questions would a careful buyer ask that my notes do not answer?"

Run one prompt at a time, read the answer, and then push back. The second and third replies are usually better than the first.

How do you check what it tells you?

Assume every confident sentence could be wrong until you have seen the evidence.

• Ask it to cite which of your notes support each claim. If it cannot, discard the claim.
• Check any number, date or named source against the original. Assistants can produce plausible figures that do not exist.
• Ask it to argue the opposite view and see whether your idea survives.
• Read the output aloud. If it sounds like a brochure, rewrite it in your own voice.
• Test the final line with real customers, as in the four-hour sprint.

You are the editor. The assistant is a fast first draft and a patient questioner.

What should you never share?

Treat a chat window like a postcard, not a sealed letter, until you have read your plan's data settings.

• Customer names, contact details and anything that identifies a person.
• Confidential figures, contracts and pricing agreements.
• Passwords, banking details and access keys.
• Anything covered by a non-disclosure agreement.
• Employee records and health or legal matters.

Replace specifics with labels such as Customer A or Large client. Check each vendor's privacy and training settings on its own page, because they differ by plan and change over time.

How does a two-hour AI-assisted sprint run?

Keep the structure simple and keep your own pen moving. Spend the first 20 minutes writing your evidence list without the assistant, so your thinking leads. Spend the next 30 minutes pasting that list in and running the pattern finder, then reading the themes against your own memory of the business. Spend 30 minutes on the doubtful buyer, pushing back on every objection that feels weak. Use the last 40 minutes to write your own final draft from scratch, with the chat closed.

That last step matters. Writing the final version yourself stops the assistant's phrasing from leaking into your marketing, and it keeps the voice recognizably yours. Save the transcript as notes, not as copy.

Claude or ChatGPT: how do they compare for this job?

Both are capable general assistants, and either will handle a sprint. The differences that matter for a solo owner are mostly practical: which plan you need, how it handles long pasted notes, and which interface you prefer. Try the same three prompts in each free tier before paying for anything.

On price, I read the official pages on 9 November 2026. Claude lists Free at $0, Pro at $17 per month when billed annually or $20 billed monthly, and Max at $100 per month. For ChatGPT, I could not get a reliable read of the current plan page, so see the vendor page for plan names and prices. Plans change often, so confirm before you subscribe.

Remember the disclosure: Simple-Growth uses Claude for some of its own work, so weigh that.
