Your AI App, Shipped in 7 Days. Not 7 Months.
We build production-grade Next.js apps for AI and LLM products — chat interfaces, streaming responses, LLM integrations, auth, and clean code your team can actually own. One focused sprint. One fixed price. Live in a week.
WHY AIZECS
Why Hire Next.js Developers for AI & LLM Apps?
Most founders waste weeks in discovery calls, endless scoping sessions, and back-and-forth NDAs before a single line of code gets written. We cut all of that. You get a scoped plan in 24 hours, a kickoff in 48, and a working AI app in 7 days.
7-Day Delivery, No Surprises
We lock scope on Day 1, demo real progress every day, and deploy on Day 7. You always know exactly what's being built — and when it ships.
Chat & Conversation UI
A polished, streaming chat interface designed to your brand — not a generic wrapper with a CSS coat of paint. Built for real users and real UX.
Any LLM, Integrated Right
OpenAI, Anthropic, Gemini, or your own model. Clean API integration with retry logic, rate limiting, and graceful error handling baked in from the start.
Streaming That Feels Instant
Token-by-token streaming so your users see responses the moment they're generated. No loading spinners. No lag. No waiting.
Auth Built In — From Day One
Clerk or NextAuth with session management, role-based access, and protected routes. Not bolted on as an afterthought.
Code You Actually Own
App Router, TypeScript, Vercel AI SDK. No black boxes. No hidden dependencies. Documented code your team can maintain, extend, or hand to any developer — anytime.
Start with one 7-day sprint to prove value, or go straight to a dedicated engineer on your roadmap. Either way, you get a scoped plan and transparent pricing within 24 hours. No retainers. No lock-in.
TECHNOLOGY
The Exact Stack Your AI App Needs
Next.js is the fastest path from LLM API to production. Server components, streaming API routes, edge-ready infrastructure — it was built for apps that have to be fast, real-time, and scalable from day one.

FAQ
Honest Answers to Common Questions
How fast can you deliver an AI or LLM app?
Most MVPs ship in 7 days from kickoff. Projects with complex RAG pipelines or multi-model setups may take 10–14 days — we'll tell you upfront during the proposal, not halfway through the sprint.
Which LLM providers do you integrate?
OpenAI, Anthropic (Claude), Google Gemini, Mistral, and any OpenAI-compatible API. We also support local models via Ollama for teams with strict data privacy requirements.
Do you support streaming responses?
Yes. We use the Vercel AI SDK or native ReadableStream for real-time, token-by-token streaming. Your users see responses as they generate — no waiting for the full output to finish.
What about RAG or custom context?
We build RAG pipelines using pgvector, Pinecone, Weaviate, or your preferred vector store. For 7-day sprints, this is included when it's in scope — something we define clearly during the proposal.
How do you handle API costs and rate limits?
We implement per-user and per-app rate limiting, token usage tracking, and configurable cost caps from day one. You'll have full visibility into consumption before you hit any surprises.
Do you work with US and European startups?
Yes. Most of our clients are in the US and EU. We work async-first with daily written updates and schedule calls across US and European timezones for demos and reviews.
