Plan AI plans, designs and develops websites, mobile apps, SaaS platforms, LLM products, AI agents, RAG, workflow automation and industrial systems. Published projects include CAD automation, a patent platform, research retrieval, interactive 3D and EV charger software. We hand over the complete source code and operating documentation.
Tell us about your idea and we will review its feasibility. If a simpler approach would work better than custom development, we will explain it. The consultation is free.
We estimate the scope, complexity and timeline, then document the agreed price and its basis before work begins. The agreed quote remains fixed for the agreed scope.
The pilot takes 14 days. Workflow automation usually takes 2–8 weeks, and AI product or system development takes 2–6 months. The exact schedule is set out in the quote.
Project data stays in your operating environment. We can agree on Zero Data Retention options, personal-data masking and an NDA during scoping.
LET’S MAKE WHAT’S NEXT.
An app, a new AI service, a complex internal system. Tell us what you want to build. We will help define the functions and the path forward.
contact@plan-ai.co.krWe reply within the same business day with feasibility, cost and timeline.
