Let's build your product!
FAQ
Can you set up real-time streaming text (like ChatGPT) inside my WeWeb app?
Yes! I configure streaming responses using server-sent events (SSE) or WebSockets through Xano, Supabase, or n8n so your WeWeb frontend displays AI-generated text in real-time as it's generated.
How do you prevent users from abusing my AI app and burning through my OpenAI API tokens?
I implement strict rate-limiting, daily query caps, credit-based usage systems, and input length validation on your backend (Xano / Supabase) before sending requests to the OpenAI API.
Can we build a custom AI chatbot trained on my company's custom knowledge base or website data?
Absolutely. Using Supabase Vector (pgvector) or Pinecone alongside n8n, I can embed your custom documents, PDFs, or website URLs so your WeWeb application delivers hyper-accurate, context-aware AI responses.
Can you connect image generation models like DALL-E 3 or Midjourney into my WeWeb app?
Yes! I can connect WeWeb frontends to image generation APIs (DALL-E 3, Midjourney via API bridges, or Stable Diffusion). Users can generate images, preview them instantly, and download or save them directly to their database profile.
Is it possible to trigger background n8n automations when a user performs an action in WeWeb?
Yes. We can fire webhooks directly from WeWeb component interactions to n8n to trigger complex background tasks—such as scraping data, generating multi-page PDF reports, sending email notifications, or updating CRMs.
Can I offer a free trial with limited AI credits, then auto-upgrade users to a paid Stripe subscription?
Yes! I engineer user onboarding flows where new sign-ups receive a free starting credit balance. Once exhausted, WeWeb prompts them to select a paid subscription plan integrated seamlessly with Stripe Billing.
Do you handle fine-tuning custom AI models for specific industry use cases?
Yes. If standard models aren't meeting your requirements, I can assist in setting up fine-tuned OpenAI models or tailored system prompts, connecting them directly to your Xano or Supabase backend API endpoints.
How do you connect WeWeb to OpenAI or other AI APIs?
We can either connect WeWeb directly to the OpenAI API for real-time responses or route requests through Xano / n8n for secure processing, database logging, and streaming outputs.
Can users upload documents (PDFs, CSVs) for the AI to analyze?
Absolutely. Using Supabase or Xano combined with n8n, we can parse uploaded files, store vector embeddings, and allow users to query their private data directly through the WeWeb interface.
Are my OpenAI API keys kept secure in WeWeb?
Yes. I never expose sensitive secret keys in the frontend visual builder. All API calls requiring secret keys are securely routed through your backend (Xano, Supabase, or n8n serverless endpoints).
