There are several add-ons that I can add to the template on a custom basis. All prices below are approximate. This includes but is of course not limited to:

• Account management - require user login or payment ($70)
• OAuth - integrate with your platform’s accounts so that users can sign in with your platform account instead of creating a new one if you choose to use accounts ($140)
• Conversation history - allow users to access their conversation history ($10 + account management)
• Web search - allow users to search the web for their answer ($35)
• Billing - integrate Stripe to make the app a premium (or freemium) tool. Bill users by conversations, messages, tokens, characters, or just a monthly subscription. ($90)
• Additional memory upload types - upload things like Google Drives, entire Notion databases, Microsoft Office files, pretty much anything you can think of to suit the data that you already have an need to put into CustomGPT. ($40 per API)
• Advanced admin panel - track conversations, token usage, user management etc. ($80)
• Analytics - implement Google Analytics / Microsoft Clarity to track user habits ($10)
