Quick Verdict

How To Build Your Own GPT is a live, interactive 90-minute workshop that walks you through creating a custom GPT from scratch inside OpenAI — covering system instructions, knowledge documents, and JSON structure. At $47 and replay access included, it's a genuinely practical entry point for marketers who want to stop depending on other people's AI tools and start building their own. The upsells add real value if you're serious about monetising your GPTs, but the core workshop stands on its own merits.

What Is How To Build Your Own GPT?

How To Build Your Own GPT is a live step-by-step workshop hosted by Sharon and Melody of GPTs & Bots Unleashed. It's designed to take complete beginners — and intermediate marketers who've been putting this off — from "I've used ChatGPT before" to "I just built my own custom GPT I can use, sell, or publish." The workshop is delivered live over approximately 90 minutes with a hands-on, screen-sharing format. Replays are included, so if you miss the live date you're not left out in the cold. The launch window runs March 16–21, 2026, on the WarriorPlus platform. What makes this one stand out from the usual "AI course" clutter is that it's genuinely interactive — you're expected to build alongside the instructors, not just watch. You even get a bonus GPT specifically designed to help you build GPTs. Yes, really.

Key Point: This isn't another passive video course. It's a live build-along workshop where you walk away with an actual custom GPT you created yourself — ready to use, publish, or sell.

How Does It Work?

Step 1 — Register for the Live Workshop: Grab your seat for the 90-minute interactive session. Seats are limited, and the live dates run March 16–21, 2026.
Step 2 — Show Up With an Idea: Come with a niche or use case in mind. The workshop guides you from concept all the way to a working GPT, so having a rough idea of what you want to build helps you get more out of it.
Step 3 — Build Live With the Instructors: Follow along as Sharon and Melody walk you through system instructions, knowledge document structure, and JSON formatting inside the OpenAI Playground — step by step, in real time.
Step 4 — Upload & Test Your GPT: You'll publish, test, and customise your GPT during the session itself. By the end of the 90 minutes, you should have a working model.
Step 5 — Use Your Bonus GPT Builder GPT: The bonus tool helps you draft system instructions, structure knowledge docs, and generate starter JSON — cutting the learning curve significantly.
Step 6 — Access Replays & Workbook: If you need to revisit any section or missed the live session, replays and a complete setup workbook are available after the event.

Heads Up on Upsells: The front end at $47 is genuinely self-contained — you can learn to build a GPT without buying anything else. OTO 1 ($37) makes sense as a natural next step if you actually want to sell your GPTs, not just build them for personal use. OTO 2 ($97/month) is a much bigger ongoing commitment — it's pitched heavily on the affiliate angle, so go in with eyes open. Only grab the membership if the white label product model genuinely fits your business.

Key Features

Live Interactive Format: This is a build-along workshop, not a pre-recorded slide deck. You're actively creating your GPT during the session alongside the instructors.
Replay Access Included: Can't make the live date? Replays are included with your purchase, so you won't miss out on the content.
Complete Workbook & Setup Instructions: A structured workbook walks you through each stage of the build so you're not left scrambling to take notes during the session.
GPT Builder GPT Bonus: A custom GPT included with your purchase that helps you draft system instructions, structure knowledge docs, and generate starter JSON — a genuine shortcut for first-timers.
JSON Made Approachable: One of the biggest blockers for non-technical marketers is JSON. The workshop specifically addresses this with clear, step-by-step guidance rather than assuming prior knowledge.
Knowledge Document Structuring: You'll learn how to correctly upload and structure knowledge files inside your GPT — something most "intro to GPTs" content completely skips over.
Niche-Specific Customisation: The training is designed to help you build GPTs tailored to your specific niche or audience, not just generic examples.
Path to Monetisation: The workshop frames GPT creation as a legitimate business asset — custom GPTs can command premium prices — with the OTO 1 expanding on the actual selling and securing process.
Accessible for Beginners: The sales page is explicit that near-beginners can benefit, and the testimonials back that up with non-technical users getting real results.
Affordable Entry Price: At $47 for a live workshop with replay and bonus tools, the barrier to entry is low relative to the potential business value of knowing how to build sellable GPTs.

Who Is This For?

Affiliate Marketers Building your own AI tools adds a genuine product layer to your business and opens up new commission opportunities via white label GPT sales.

Digital Product Creators If you already sell ebooks, courses, or templates, custom GPTs are a natural premium add-on — and now you can build them yourself.

Bloggers & Content Creators Automate niche-specific content workflows with a GPT built exactly for your style, audience, and topic — not a generic prompt tool.

AI Curious Beginners If you've been using ChatGPT but feel like you're just scratching the surface, this workshop gives you a structured path to the next level without needing a tech background.

Freelancers & Agency Owners Package custom GPTs as client deliverables or internal workflow tools. The OTO 1 specifically helps you lock these down for safe client delivery.

Small Business Owners Build AI tools tailored to your own business operations — customer support, content creation, product descriptions — without hiring a developer.

Pros & Cons

Pros

Genuinely hands-on format — You build a real GPT during the session, not just watch someone else do it.
Replay included — No pressure to block out a specific time slot; you can absorb the content at your own pace after the live event.
The GPT Builder GPT bonus is clever — Using AI to help you build AI is a smart shortcut that actually reduces the learning curve meaningfully.
Tackles the real blockers — JSON, system instructions, and knowledge doc structure are the three things that stop most people. This workshop addresses all three directly.
Strong testimonials with specificity — The social proof isn't vague "changed my life" fluff; testimonials mention actual outcomes like ranking for keywords and starting to sell GPTs.
Logical funnel progression — Build it (FE) ? Secure & sell it (OTO 1) ? Scale with a monthly product library (OTO 2). Each step adds genuine value rather than padding.
Low entry price for the value — $47 for a live workshop, replay, workbook, and bonus tool is a reasonable ask, especially given the earning potential of custom GPTs.

Cons

Requires a paid OpenAI account — You can't complete the workshop on the free tier. The sales page says it'll cost "pennies per use," but it's still an additional cost to factor in.
OTO 2 is a significant monthly commitment — $97/month is not a casual purchase. The pitch leans heavily on the affiliate angle, which won't be relevant to every buyer.
Live event dependency — While replays are included, the core experience is built around a specific live window (March 16–21, 2026). Latecomers get the content but miss the interactive element.
No explicit money-back guarantee mentioned — The sales and JV pages don't prominently feature a stated refund policy, which may give cautious buyers pause before purchasing.
Workshop depth limited to 90 minutes — For complete beginners, 90 minutes is a brisk pace to cover system instructions, knowledge docs, JSON, and publishing. Some attendees may need the replay to absorb everything fully.

The Guarantee

Guarantee Information: The sales page and JV materials reviewed do not explicitly state a formal money-back guarantee period for this workshop. This is worth noting before you buy. That said, the product is hosted on WarriorPlus, which has its own buyer protection policies and dispute process. If a guarantee is important to you, I'd recommend reaching out to the support team at Support@GPTsandBotsUnleashed.com before purchasing to confirm the refund policy directly. Based on the instructors' reputation and track record with previous workshops, the risk profile here is relatively low — but go in informed.

My Yeti Marketer Personal Take

Alright, let me be straight with you — I've sat through a lot of AI workshops over the past couple of years. Most of them are glorified sales presentations with a thin layer of "education" painted over the top. This one feels different, and I think it comes down to format. The fact that it's genuinely hands-on matters. You're not watching Sharon and Melody build something while you take notes. You're building alongside them. That's a meaningful distinction if you've ever bought a "how to do X" product and then done nothing with it because the format didn't force engagement. The GPT Builder GPT bonus is one of those ideas that sounds gimmicky on paper but is actually quite clever in practice. Using a GPT to help you structure the thing you're trying to build reduces the cognitive load at exactly the right moment — when you're still figuring out what system instructions even are. My main reservation is the OTO 2. The $97/month Secret Society membership is being pitched very hard on the affiliate commission angle — "five referrals = $2K+ without another launch" type language. That's not a bad pitch, but it means the product is partly being sold as an affiliate asset rather than purely on its educational or tooling merits. If you're a marketer who can move referrals, the recurring commission structure is genuinely compelling. If you're just a regular buyer who wants to build GPTs, you probably don't need it to get value from this purchase. The front end at $47 is solid. OTO 1 at $37 makes logical sense if you want to actually sell what you build. Together they're $84 for two live workshops that take you from zero to a sellable, protected custom GPT. That's a fair price for the outcome if the instruction quality holds up to the testimonials. I'm giving this a 4 out of 5. It loses a point primarily because there's no clearly stated guarantee and the 90-minute runtime will feel rushed for true beginners albeit there is the replay. But for a hands-on, practical, affordably priced workshop on a skill that has genuine business value in 2026 and beyond — this one's worth your consideration.
