| Fact | Thumbn | ThumbnailCreator.ai |
|---|---|---|
| Authentication | API requests use an x-api-key or bearer token, while MCP uses OAuth 2.1 with authorization-code PKCE and refresh tokens. | The web studio supports Google or email-link sign-in, and MCP users can connect with an agent key or OAuth connector. |
| Integrations | Thumbn supports bringing Google, OpenAI or Anthropic API keys for rendering billed directly by those providers. | The MCP server works with Claude, Cursor, ChatGPT and other MCP clients; the site also offers an Agent Skill and x402 pay-per-call. |
| Product | Thumbn watches video scene by scene, selects a moment, writes a thumbnail concept, and renders images for video platforms. | ThumbnailCreator runs one prompt through up to four image models at once so users can compare thumbnail results side by side. |
| Reference images | Projects can include reference images so faces, logos, products or brand colors remain more consistent. | Users can upload up to four reference images for supported models, including faces and products. |
