Doppus is an established Brazilian checkout and digital-product delivery platform, with native integration to the Cademí member area — a common pairing among creators selling courses and ebooks in Brazil. If what you sell is recorded content with automatic delivery, it handles that well. But one thing needs to be clear upfront: Member AI has no integration with Doppus — or with Cademí, or with any other checkout platform. There's no such thing as "selling AI inside Doppus." What exists is a different, separate product: an AI agent you build on Member AI, host on your own domain, and sell with direct Stripe Connect, entirely outside the Doppus + Cademí ecosystem.
Why does that matter? Because the recorded course or ebook model has a clear ceiling: it saturates fast, suffers from refunds and piracy, goes stale, and turns into manual support that doesn't scale. An AI agent on your own SaaS solves that a different way: it answers instantly, personalized to each subscriber's case, with no per-sale fee — just the flat subscription of a platform like Member AI. This article shows when it's worth keeping Doppus + Cademí for the recorded product and building that agent as a separate product.
Why Doppus + Cademí is a common combo for digital products
- Robust, reliable checkout · processes one-time and recurring payments without surprises.
- Automatic digital product delivery · the customer gets access as soon as payment clears.
- Native integration with Cademí · a ready-made member area for hosting video, PDFs, and recorded lessons.
- Affiliate support, which helps scale traffic without depending only on your own paid media.
That makes the Doppus + Cademí pair, a common Brazilian checkout and course-hosting combo, a solid choice for a course or ebook with automatic delivery. The problem shows up when the recorded-course format is already worn out: it saturates fast, refunds climb when expectations don't match reality, piracy spreads the material in a private group within days, content goes stale and turns into manual support that doesn't scale. The 2026 buyer doesn't want to watch 40 hours of video to find the answer to their specific case anymore — they want an instant, personalized answer. That's exactly what an AI agent delivers, and what recorded video on Cademí can't deliver on its own.
Why Doppus + Cademí isn't the place to sell an AI agent
- No agent builder. Cademí hosts video, PDFs, recorded lessons — there's no tool to train a conversational agent on your materials.
- No BYOK. You can't plug your OpenAI, Anthropic, or Google key into the Doppus + Cademí combo. For real AI, the agent needs to exist as a separate product, on a different platform.
- The domain belongs to the platform, not you. Even with Cademí's own look, the student stays inside the Doppus ecosystem, not inside your single SaaS.
- The per-sale fee bleeds over recurring billing. In a typical checkout-platform range, 200 subscribers at $20/month already exceed $2,900/year in fees alone (estimate — always check Doppus's current official table).
The alternative: an AI agent as a separate product
Member AI doesn't replace or connect to Doppus — it solves, as a separate product, what Doppus + Cademí don't: agent builder + own checkout + BYOK + custom domain.
You build the agent in ~15 minutes (master prompt + knowledge base from PDFs/docs + contextual memory), point your domain with auto SSL, connect your Stripe Connect account, and get paid directly in BRL, USD, or EUR. Member AI only charges the flat plan subscription · 0% on every recurring sale. Multiply that by 1,000 subscribers at $20/month and you reach $20,000/month in predictable MRR — a product that runs alongside what you already sell on Doppus, not inside it.
Doppus vs Member AI: financial comparison
Concrete scenario: 200 subscribers, $20/month, 12 months. Since Doppus doesn't publish a single fixed fee — it varies by payout method and volume — the figure below is an estimate within the typical range for Brazilian checkout platforms. Always check the current official table.
| Doppus + Cademí (recorded course) | Member AI + direct Stripe (AI agent) |
|---|
| Annual gross revenue | $48,000 | $48,000 |
| Doppus fee (estimated, ~5% + $0.20) | −$2,880 | $0 |
| Manual support for recorded content (~$160/month) | −$1,920 | $0 |
| Member AI Expert ($50/month flat) | $0 | −$600 |
| Direct Stripe (~3.99% + $0.08) | $0 | −$2,107 |
| AI cost via BYOK (~$1.60/user/month) | −$3,840 | −$3,840 |
| Annual net | $39,360 | $41,453 |
12-month difference at 200 subscribers: +$2,093 in favor of the AI agent as a separate product. At 500 subscribers, the gap exceeds $5,200/year. And the product itself is different: an instant, personalized answer instead of a recorded video the student has to scrub through to find the right part.
Step-by-step for an AI SaaS from scratch
- Member AI account (Basic $20 or Expert $50, depending on volume).
- Build the agent in ~15 min · full tutorial.
- Turn the content already on Cademí (lessons, PDFs) into a knowledge base · see how to structure it.
- BYOK: plug your OpenAI, Anthropic, or Google key · see why it matters.
- Custom domain with auto SSL.
- Stripe Connect: connect your account and get paid directly in BRL/USD/EUR.
- Launch on
yourdomain.com, as a product separate from what you already sell on Doppus. The subscriber logs in, chats with the agent, and gets an instant answer.
When Doppus wins vs direct SaaS
Doppus + Cademí make sense for:
- A recorded course or ebook as the main product, with no AI component.
- One-time high-ticket sales where the affiliate structure helps scale traffic.
- Beginner creators who want ready-made checkout and a member area, no coding.
An AI agent as a separate product wins for:
- Expert-answer products with monthly recurring billing.
- Creators with their own audience who already sell a course and want to add a better-margin product.
- Anyone building a brand and keeping customer data (the subscriber is yours, not the platform's).
- Operations above $50/month in recurring revenue — that's where fee savings outweigh any affiliate-reach advantage.
Migrate a Doppus product to your own SaaS
If you already sell a course or ebook on Doppus + Cademí and want to add (or replace it with) an AI agent product:
- Coexistence (3-6 months). Build the SaaS on Member AI in parallel, using the content already on Cademí as the agent's knowledge base. Doppus keeps selling the course meanwhile.
- Upgrade email to your customers: "I built an AI agent that answers your questions instantly — get 30 bonus days if you subscribe by [date]."
- Active migration. Customers who already paid for the course get access or a discount on the new agent. Typical conversion: 60-80%.
- Final call. Once 80%+ have migrated to the agent, decide whether to keep the recorded course on Doppus as an entry-level product or shut it down.
Full playbook in how to migrate a course to an AI agent without losing revenue.
Decision by creator profile
- Selling a recorded course or ebook? → Doppus + Cademí win on ready-made structure and affiliates.
- Want an expert-answer, recurring product? → An AI agent on Member AI + direct Stripe wins on margin and experience.
- Want to start simple and cheap? → Member AI Basic $20/month + direct Stripe. A single product, separate from Doppus.
- Already have an audience and want to add better-margin recurring revenue? → An AI agent as a separate product, always.
