AI chatbots ChatGPT and Claude applied SPIN Method to fully automate my sales
I never liked cold calling. It felt outdated, inefficient, and, frankly, exhausting. When I decided to bring artificial intelligence and an advanced chatbot into my B2B sales process, my goal was simple – eliminate cold calls without losing leads. After testing countless tools, I locked in on ChatGPT from OpenAI and Claude from Anthropic, pairing them with the SPIN Selling framework. What happened next was not magic but a mix of sharp prompt engineering, data-driven targeting, and an obsession with personalization. In this article, I’ll share the exact SPIN-based funnel I built, the prompts that worked, and the setup that keeps my calendar full without dialing a single number.
ChatGPT and Claude for the “Situation” stage: cutting research time by 80%
When starting with the SPIN method, the “Situation” stage is where most sales reps lose momentum – endless research, repetitive questions, and scattered notes. I trained ChatGPT and Claude to pull in CRM data, LinkedIn profiles, and industry insights in seconds. Instead of manual digging, I now get a clean, client-ready summary in under 90 seconds.
Prompt I use:
“Given this CRM data and LinkedIn profile, create a concise, 150-word situation summary. Highlight company size, recent news, and potential business challenges without generic statements.”
By feeding the AI both structured and unstructured data, the responses feel natural and deeply relevant – the kind that makes prospects say, “You’ve clearly done your homework.”
ChatGPT and Claude for “Problem” stage: surfacing pain points they don’t mention
The “Problem” stage is about uncovering friction the client hasn’t put into words yet. ChatGPT is great at identifying hidden operational inefficiencies, while Claude tends to spot tone-based cues in meeting transcripts. Together, they flag issues before I even ask.
Mini workflow:
- Transcribe discovery calls with an AI note-taker.
- Send transcript to Claude with the prompt:
“Extract 3-5 core business problems hinted at in this conversation, even if not stated directly. Rank by urgency.” - Feed results into ChatGPT to create tailored follow-up questions.
This two-step AI approach turned my average discovery call from “interesting” to “insight-packed” – and prospects notice the difference.
ChatGPT and Claude for “Implication” stage: making the cost of inaction crystal clear
In SPIN Selling, showing the implications of a problem is where deals accelerate. Claude helps me phrase implications in a way that feels advisory, not pushy. ChatGPT turns those implications into ROI-based forecasts.
For example, a logistics prospect mentioned minor delays. Using ChatGPT, I turned that into a quantified annual revenue loss projection. They saw the number and moved from “we’ll think about it” to “let’s fix this now.”
Prompt for ChatGPT:
“Based on these operational delays and average revenue per delivery, estimate the annual revenue impact if the issue remains unresolved for 12 months.”
Numbers talk, and AI makes sure they’re always relevant and accurate.
Using a unified AI workspace for SPIN Selling
Halfway through implementing this system, I realized juggling multiple tools slowed me down. I wanted one place where ChatGPT, Claude, and other top AI models could work side by side, with my prompts and outputs neatly organized.
That’s when I switched to a unified workspace that let me run six AI models in one chat, compare their answers instantly, and store prompt templates for reuse. The bonus?
10 free requests to test it, turbo mode for faster responses, and side-by-side comparisons so I could pick the best output without second-guessing.
Since moving my SPIN workflow there, I’ve saved hours each week and increased deal velocity without adding headcount.

ChatGPT and Claude for “Need-Payoff” stage: crafting offers they can’t refuse
At this stage, I use ChatGPT to design ROI-driven proposals and Claude to refine the tone so it feels collaborative, not transactional. This balance consistently bumps my close rate.
One small change that made a huge impact – replacing “We can solve this by…” with “If we solve this, here’s what you gain…”. Claude naturally leans toward this framing, and it lands better with decision-makers.
Prompt I give Claude:
“Rewrite this proposal section to emphasize the client’s gains and outcomes, avoiding sales jargon and keeping a consultative tone.”
Table: My SPIN AI Workflow
| SPIN Stage | ChatGPT Role | Claude Role | Output Benefit |
| Situation | Data synthesis, summary creation | Additional context, softer tone | Saves research time |
| Problem | Creates probing questions | Detects unstated pain points | Deeper, faster discovery |
| Implication | Quantifies costs of inaction | Frames implications diplomatically | Moves deals faster |
| Need-Payoff | ROI-based proposal drafts | Collaborative tone adjustments | Higher close rate |
Final thoughts
ChatGPT and Claude didn’t just make my sales process faster – they made it sharper. With SPIN as the backbone, AI does the heavy lifting while I focus on human connection. If your sales team still relies on cold calls, you’re leaving opportunities (and energy) on the table.
