ChatGPT plan requirements
Plugin support depends on your ChatGPT plan and workspace settings.
| Plan | FactIQ plugin support |
|---|---|
| Pro, Business, Enterprise, Edu | Supported. On Business, Enterprise, and Edu a workspace admin or owner may need to enable developer mode or approve the plugin. |
| Free, Go, Plus | Not yet supported — custom plugins like FactIQ aren’t available on these plans. |
ChatGPT's plugin and MCP features are in beta and may change (last reviewed July 2026).
Try it
Ask an economic or financial question normally, or type @FactIQ to select it explicitly.
- What's the US unemployment rate, charted over the last 10 years?
- Compare US and China CPI inflation year-over-year for the last five years.
- Plot the US 10-year Treasury yield, monthly, since 2020.
Troubleshooting
- No Plugins in the sidebar
- Plugins live in the ChatGPT desktop app — not web, mobile, or the IDE extension. Update the app if you don’t see the Plugins item.
- FactIQ marketplace missing
- Confirm the repository is exactly
defog-ai/factiq-plugin, then look for thefactiqmarketplace with your custom plugins. Restart the app if it doesn't appear. Directory changes can take up to six hours to refresh on Codex — restart Codex or refresh the plugin data before retrying. - OAuth gets stuck
- Sign in to FactIQ in the same browser, then retry. You can also remove the plugin and add it again.
- Tools missing in chat
- Bundled skills load in new conversations after installation. Start a fresh chat and type
@FactIQto select it explicitly.
