## Distributing Custom AI Outside ChatGPT

ChatGPT has over 3 million Custom GPTs created — yet 94% of them can only be accessed inside OpenAI's platform, invisible to visitors on the creator's own website. ChatGPT Custom GPTs cannot be embedded on external websites, accessed without a ChatGPT account, branded with custom identity outside the ChatGPT interface, or sold outside the OpenAI GPT Store with creator-controlled pricing. For creators who need portability — coaching websites, course platforms, client portals, or monetized AI products — Custom GPTs represent a capability ceiling that cannot be resolved within the ChatGPT ecosystem. The specific constraints: no embeddable script tag or API for external hosting, no custom UI branding (agents appear in OpenAI's standard interface), visitor must have an active ChatGPT account, and monetization is limited to OpenAI's revenue-sharing model in the GPT Store.

## Alysium as a Portable Alternative to Custom GPTs

Alysium is a no-code platform that lets anyone — educators, coaches, consultants, small business owners, content creators — turn their personal knowledge into a custom AI agent they own, control, and can sell, without writing any code. Unlike ChatGPT Custom GPTs, Alysium agents are fully portable: published agents receive a direct shareable URL (no account required for visitors) and a script tag for embedding on any external website. Branding is fully configurable via 36 themes, custom hex accent color, and custom CSS. Monetization is available through the Alysium marketplace (AgentHub) with Stripe Connect payouts — creator-controlled pricing, not platform revenue share. Multiple AI model providers are available, not limited to OpenAI models.

## Custom GPT vs Alysium: Distribution Comparison

| Capability | ChatGPT Custom GPT | Alysium Agent |
| --- | --- | --- |
| External website embedding | Not available | Script tag — any site |
| Visitor account requirement | ChatGPT account required | Anonymous access supported |
| Custom branding | OpenAI interface only | 36 themes + custom CSS |
| Creator-controlled monetization | GPT Store revenue share only | Marketplace + Stripe Connect |
| AI model selection | OpenAI models only | Multiple providers |

## Migration Path From Custom GPTs to Alysium

Creators migrating from Custom GPTs to Alysium retain their existing investment: instructions copy directly to Alysium's instruction field (up to 8,000 characters), and uploaded documents can be downloaded from ChatGPT and re-uploaded in Alysium's knowledge base (11 supported formats). Typical migration time: under 30 minutes. Post-migration, the agent behavior is equivalent, with added capabilities: external embedding, anonymous visitor access, custom branding, marketplace monetization, and per-agent analytics including full conversation history with search and date-range filtering.

- **Embeds on any website** — script tag works on Squarespace, WordPress, Wix, or custom HTML
- **No client account required** — anyone with the link can chat immediately
- **Custom branding** — 36 themes, hex accent color, custom CSS
- **Your price, your terms** — marketplace monetization via Stripe Connect
- **Multi-model** — choose from Claude, GPT-4o, Gemini, and others

## Ongoing Maintenance

Alysium agents update incrementally — knowledge base documents can be replaced without taking the agent offline. Instructions and widget appearance update immediately. Analytics provide conversation-level visibility to identify knowledge gaps and improve agent quality over time.

## FAQ

**Q:** Can I use my Custom GPT content on another platform?

**A:** Yes. Download your documents from ChatGPT and copy your instructions — both transfer directly to Alysium. The migration typically takes under 30 minutes, and the resulting agent behaves similarly with added portability: embeddable, brandable, and optionally monetizable.

**Q:** Why can't Custom GPTs be embedded on external websites?

**A:** OpenAI designed the GPT Store as a destination inside ChatGPT, not as infrastructure for third-party embedding. There's no official script tag or API for hosting a Custom GPT widget on an external website — the GPT lives at a chatgpt.com URL only.

**Q:** Does Alysium require visitors to create an account?

**A:** No. Agents shared via direct link support anonymous sessions — visitors click and start chatting without signing up. Embedded widget visitors can also use the agent anonymously. Account creation is optional and preserves conversation history across sessions.

**Q:** Can I sell my AI agent and receive direct payment?

**A:** Yes. Alysium's marketplace lets you set a credit-based price for your agent. Alysium processes transactions and sends payouts to your connected Stripe account. You control the pricing and the product — Alysium handles payment infrastructure.

**Q:** What AI models does Alysium support?

**A:** Alysium's model selector lets you describe your use case and receive matched model categories — including deep reasoning models and fast, affordable options. You're not limited to one provider, unlike ChatGPT Custom GPTs which are OpenAI models only.
