What the AI Dev Planner blog covers

This blog is written by the engineering team behind AI Dev Planner for founders, product owners and technical leads who are planning or building software. Articles focus on the decisions that shape a product before and during development: what to build first, how to structure it, and what it is likely to cost.

You will find guides on SaaS product engineering, from multi-tenant architecture to subscription billing, alongside practical writing on AI engineering, including LLM integrations, retrieval-augmented generation and AI agents. We also cover custom web applications, customer portals and internal tools, plus idea validation frameworks that help you test demand and scope an MVP before committing a full budget.

If you are budgeting a build, start with our custom web application development cost guide (UK figures, in GBP). If you are ready to talk about a project, explore our software development services, including SaaS development, AI development and LLM integration and custom web application development.
