A few things you might be wondering
What if I don’t see Developer Mode?
Check your plan and workspace permissions. If the option is unavailable, you can create the same invitation on the Lemonvite website. Installing the Codex plugin does not install Lemonvite in ChatGPT.
What can I do with Lemonvite in my assistant?
Create and edit invitation drafts, manage guests, publish invitations, and check RSVPs. Your assistant gives you a link to manage the event on Lemonvite, where you can also choose a design and review everything before sending.
Will creating a draft send anything to my guests?
No. Creating a draft does not publish the event, spend a publish credit, or contact guests. Review your invitation and guest list before asking your assistant to publish. Publishing sends invitations and uses a publish credit.
Does connecting cost anything?
Lemonvite does not charge to connect or create an invitation draft. Publishing uses a paid event credit. Your assistant may have its own plan requirements. You can check Lemonvite’s current event pricing on our pricing page.
What can my assistant access?
Once connected, your assistant can work with the events, invitation details, guests, and RSVP responses available to your Lemonvite account. You review the requested permissions when connecting. Sign in on Lemonvite; do not paste your password into a chat.
How do I disconnect Lemonvite?
Remove or disconnect Lemonvite in your assistant’s connector or app settings. You can also revoke the connection from Connected assistants in your Lemonvite account settings.
