I will add openai chatbot or ai features to your next js app


Level 2
About this gig
Want to add a practical OpenAI feature to your existing Next.js app without rebuilding the whole product?
I integrate focused AI features into Next.js products: OpenAI API chatbot flows, assistants, summarizers, classifiers, structured outputs, text generation, and dashboard AI actions.
What I can integrate:
- AI chatbot or assistant
- summarization
- text generation
- rewriting
- classification
- structured outputs
- AI workflow steps
Common use cases include support chat, admin assistant, content helper, dashboard automation, form analysis, lead qualification, or AI response generation inside a SaaS product.
Basic is for one prompt-based AI feature without database storage. Standard is for a complete assistant/chat flow, saved history, or structured output workflow. Premium is for 2 focused AI features or 1 advanced workflow with database integration.
Not included by default: full SaaS builds, advanced RAG, vector search, fine-tuning, custom model training, or large backend architecture.
OpenAI/API usage costs are paid by you.
Please message me with the feature, user flow, example input, and expected output.

FAQ
What kind of OpenAI features can you add?
I can add AI assistants, text generation, summarization, rewriting, classification, structured outputs, and similar OpenAI-powered features inside your Next.js app.
Can you start without repo access?
No. I need access to the current codebase through GitHub/GitLab or a full ZIP archive before I can integrate the feature.
Do I need an existing Next.js app?
This gig works best for existing or partially built Next.js apps. If you need a full app from scratch, my SaaS MVP gig is a better fit.
Can you build chatbot or assistant features too?
Yes. Chatbot and assistant-style flows are one of the common use cases I can integrate in this gig.
Do you use OpenAI API directly?
Yes. I integrate OpenAI API securely into your Next.js app and guide proper environment variable setup.
Is RAG or vector database included?
Not by default. This gig is for focused OpenAI feature integration. Advanced RAG, vector search, document search, or custom retrieval setups need a custom scope.
Are OpenAI API costs included in your price?
No. API usage costs are paid by you directly through your OpenAI or provider account.
Do I get the source code?
Yes. You receive the full source code, and I can also work directly in your GitHub repository.
Will you need my OpenAI API key?
I prefer secure project-based setup or environment variables. Please do not paste secret keys in chat.
Do you provide support after delivery?
Yes. I include a short bug-fix support window after delivery. Larger upgrades can be done through a custom offer.
