# AI for coaches and consultants: real situations, tested > Two real situations coaches wrote about in public: a session missed because of a booking mix-up, and a client who fell more than $10,000 behind on fees. We built a prompt from the facts each coach shared, and ran it once on OpenAI's GPT-6.1 Sol and Anthropic's Claude Sonnet 5.5 on October 25, 2026. Below is the real story, what each AI wrote, where it slipped, and the check that catches it. - Page: https://hoursaved.com/for/coaching/ - Tested: 2026-10-25, once per model, on situations from real owners' public posts - Models: GPT-6.1 Sol (OpenAI, the company behind ChatGPT), run through OpenAI's Codex command-line tool; Claude Sonnet 5.5 (Anthropic), run through the Claude Code command-line tool - Status: Draft (not yet approved by the publisher) ## How we tested Each situation comes from a real public post, linked under it. We retold it in our own words and left names out of our retelling. We then wrote a prompt from the facts in the post, set at the moment the owner had to write a message. Anything the post doesn't say is left in [brackets], and anything we had to set up for the test is listed under each situation. Each prompt ran once per model on October 25, 2026, through each company's developer command-line tool: OpenAI Codex (in a clean setup with no personal instructions; Codex reported its reasoning setting as "none") and Claude Code (with no tools and only a one-line system prompt, "You are Claude, a helpful AI assistant."). We added no other instructions beyond the prompt shown. These are the AI companies behind ChatGPT and Claude, but the chat apps can use different models and settings, so your answers may differ. The answers are the models' exact words; only the formatting is adapted for the page. One run is a snapshot, not proof. ## Where the stories come from Both stories are from coaches' own public posts, linked under each one. We add more as we find real, recent posts. ## What we saw overall - Both AIs got both situations right: neither offered a refund, a free session, a discount or a way back the coach hadn't decided on. - GPT-6.1 wrote the shortest drafts. Claude listed more decisions for you to make (what to offer, whether sessions can restart) and left them out of the email rather than guess. ## 1. Apologize after you miss a client's session A missed session is the fastest way to lose a client's trust. The risk is an apology full of excuses, or the AI offering a refund or a free session you never decided on. **The real story:** Her scheduling tool was supposed to block weekend bookings. She checked on Friday, saw nothing booked for the holiday Monday, and took a long weekend. On Sunday evening a client booked a Monday session. He waited at his computer, then emailed that he'd signed off. She found his email at 5:30 the next morning. **What the owner did:** A few hours later she apologized with no excuses and promised it wouldn't happen again. Her post doesn't say whether she offered a refund or a new session.

It put an UNCLEAR line inside the email itself, so fill it in or delete it before sending. **Check before you send:** - Every UNCLEAR note and [bracket] is filled in or deleted. - You offer only what you've decided: a new time, a refund, or just the apology. - No "it won't happen again" unless you've fixed what caused it. - It sounds like you, not a form letter. Full step-by-step guide: https://hoursaved.com/guides/draft-routine-email-replies/ ### The prompt we used ``` I'm a one-to-one coach. I missed a client's session and need to write him an apology. Use only the facts below. Don't send anything. What happened: My scheduling tool was supposed to block weekend bookings. On Friday I checked and saw nothing booked for Monday, which was a public holiday, so I took a long weekend. On Sunday evening the client booked a session for Monday afternoon. On Monday he waited at his computer for a while, then emailed me to say he had signed off. I saw his email at 5:30am on Tuesday. Client: [client first name]. Me: [my name]. What I'm offering to make it right: I haven't decided yet. Write: 1. A short apology email to the client. Own the mistake. No excuses. 2. A list of what I need to decide before I send it. Rules: - Don't offer a refund, free session or discount unless I listed it above. - Don't promise anything I haven't told you I will do. - If anything is missing or unclear, write UNCLEAR next to it. ``` ### What GPT-6.1 Sol wrote (word for word) ``` 1. Apology email Subject: Apology for missing your session Hi [client first name], I’m sorry I missed your session on Monday and left you waiting at your computer. It was my responsibility to be there, and I let you down. I saw your email at 5:30am on Tuesday. I’m sorry for wasting your time. [my name] 2. What to decide before sending - **UNCLEAR:** What, if anything, you want to offer to make this right. - **UNCLEAR:** Whether you want to propose rescheduling and, if so, what times you can commit to. - **UNCLEAR:** The client’s first name and your name—replace the placeholders. ``` ### What Claude Sonnet 5.5 wrote (word for word) ``` **Subject:** My apologies for missing our session Hi [client first name], I'm sorry I wasn't there for our session on Monday afternoon. You booked it, logged on and waited, and I never showed up. That was my mistake, and I'm sorry for wasting your time. I also didn't see your email until 5:30am on Tuesday, so you had no reply from me. UNCLEAR: what I'm offering to make it right. Not decided yet, so add it here once it is. Again, I'm sorry. [my name] --- **Decisions before you send** 1. **What you're offering to make it right.** UNCLEAR. Options include a rescheduled session, a refund, a free session, a discount, or nothing beyond the apology. I haven't offered any of them. Whatever you choose, only promise what you will actually do. 2. **Whether to propose a new time.** UNCLEAR. If you want to offer one, you'll need to supply the details, and I haven't written any in. 3. **Whether to mention the scheduling tool.** UNCLEAR. I left it out because it could read as an excuse. You could mention it briefly, or say nothing. 4. **Whether to mention the long weekend or the holiday.** UNCLEAR. I left both out, again to avoid sounding like an excuse. Think about whether he'd feel something is missing without them. 5. **Whether to disclose that you saw his email at 5:30am Tuesday.** I included it as a plain fact. Cut it if you'd rather not. 6. **How long he waited.** UNCLEAR. You said "a while" and I don't have a figure, so the email doesn't state one. 7. **The exact session time and date.** UNCLEAR. I wrote "Monday afternoon" because that's all I have. Add the specifics if you want them. 8. **Whether to fix the scheduling tool and say so.** UNCLEAR. I've promised nothing about this. Decide whether you'll act on it and whether to tell him. 9. **Delivery.** UNCLEAR whether to send by email only or also call or message him, and when to send, given it's already after Tuesday morning. Nothing has been sent. ``` ## 2. Tell a client you're pausing sessions and sending her balance to collections Coaches keep coaching clients who stop paying, hoping it turns around. When you finally act, the risk is an email that adds interest, legal threats, guilt or a way back you never decided on. **The real story:** Over a year he kept coaching a client whose fees went unpaid, expecting a breakthrough. Her promises to pay came and went, and she ended up owing him more than $10,000. **What the owner did:** He paused her sessions and started collections. His lessons: get paid up front, tighten onboarding before the first invoice, and take early red flags seriously.

The prompt asks for the email telling her both decisions, with the balance left in [brackets]. - **GPT-6.1 Sol (OpenAI): Got it right.** Three short sentences: sessions paused, the balance, and collections. Nothing added. It doesn't say whether sessions could ever restart, which is your call. - **Claude Sonnet 5.5: Got it right.** Same decisions, a little longer, and nothing offered. It pointed out you gave no conditions for restarting sessions and left that out on purpose. It added today's date from the computer's clock, so check it's the day you send. - **Watch:** The coach's own lesson matters more than any email: take payment up front, or pause sooner. A good reminder can't undo a year of unpaid sessions. **Check before you send:** - The balance is exact and matches your records. - Collections is mentioned only because you've really started it. - No interest, fees or legal threats your agreement doesn't include. - Decide whether sessions can ever restart before you say anything about it. Full step-by-step guide: https://hoursaved.com/guides/payment-reminder-emails/ ### The prompt we used ``` I'm a business and personal coach. Over the past year a client fell behind on her coaching fees while I kept coaching her. She now owes me more than $10,000. Exact balance: [exact balance]. She has promised to pay several times, and the payments haven't come. I have decided to pause her sessions as of today and to send the balance to collections. Write one email to her that tells her both decisions and states the balance. Rules: - Use only these facts. Don't send anything. - No interest, late fees, legal threats or offers I didn't give you. - Calm and direct. No guilt. - If anything is missing or unclear, write UNCLEAR next to it. ``` ### What GPT-6.1 Sol wrote (word for word) ``` Subject: Coaching Sessions Paused and Outstanding Balance Hi [client name — UNCLEAR], I am pausing your coaching sessions effective today. Your outstanding balance is [exact balance — UNCLEAR], which I am sending to collections. [Your name — UNCLEAR] ``` ### What Claude Sonnet 5.5 wrote (word for word) ``` **Subject:** Pause of coaching sessions and outstanding balance Hi [client name – UNCLEAR], I'm writing to let you know about two decisions regarding our coaching work. As of today, October 25, 2026, I am pausing your coaching sessions. Over the past year, your fees have fallen behind while I continued to coach you. Your outstanding balance is **[exact balance – UNCLEAR]**, which is more than $10,000. We have spoken several times about payment, and the payments have not been received. I have also decided to send this balance to collections. [Your name – UNCLEAR] --- **Notes on what's unclear:** - **Client name:** not provided. - **Exact balance:** the placeholder "[exact balance]" was never filled in. You only gave "more than $10,000," so I left the amount for you to insert rather than guess. - **Your name and signature:** not provided (your email suggests a first name, but I didn't assume). - **Collections agency/timing:** you didn't say which agency, or when the transfer happens, so the email says only that you've decided to send it. Tell me if you want a date included. - **Resuming sessions:** you said "pause," but gave no conditions for resuming. I left that out rather than add an offer you didn't authorize. I haven't sent anything. ``` ## Don't paste into AI - What clients tell you in sessions: health, family, money or workplace conflicts. - Clients' full names together with their employer or role. - Contracts, invoices or bank details with account numbers. - Anything a client asked you to keep private. ## Questions coaches and consultants ask **Which is better for a coach, ChatGPT or Claude?** In these two tests both did well. OpenAI's GPT-6.1 Sol wrote shorter drafts; Claude Sonnet 5.5 listed more decisions for you to make. On our cleaning and plumbing pages, Claude added promises more often. We tested through each company's developer tool, not the chat apps, so read the whole answer and use the check under each situation. **Can I paste my session notes into AI?** Only after you take out names and anything sensitive: health, family, money, workplace conflicts. Use initials or "the client". Check your coaching agreement and the AI tool's privacy settings first. **Do I need a paid AI plan for this?** Not necessarily. Free plans may use a different or smaller model, so the answers can differ from ours, but the prompts and the checks still apply.
