Write a PRD designers, engineers, and AI agents can actually use

Most PRDs are either too vague or too bloated. A useful PRD defines users, flows, states, data, priorities, acceptance criteria, and boundaries clearly enough for people and AI agents to build from.

Information architecture should happen before interface design

Information architecture gives a product its structure before the pixels arrive. It clarifies navigation, page relationships, content groups, objects, and user paths.

Technical architecture is a product decision

Technical architecture is not only engineering planning. It defines the system boundaries, data model, integrations, security, scalability, and tradeoffs that shape the product.

Why every AI app looks the same — and what it costs you

AI made it trivial to ship a working product. It also made everything look identical. Here's why AI apps have collapsed into the same interface — and why deliberate design is now the differentiator, not the decoration.

AI is not your product. The experience is.

Founders keep pitching the model. Users only ever meet the experience. Why the intelligence is the cheap part, and the trust, clarity and judgment around it are what actually make an AI product succeed.

Design and engineering shouldn't be a handoff

In AI products, the design and the intelligence are the same decision — so splitting them across a wall produces generic, brittle results. Why the strongest AI teams fuse product design and engineering instead of passing work between them.

Sizing up the competition: how to find the wedge only you can own

'No competitors' is a red flag, not a green light. Here's how to map the AI landscape, read what users hate about existing tools, and find the narrow wedge you can actually win.

Finding the core loop: how to scope an AI MVP that ships

Most AI MVPs try to do everything and ship nothing. Here's how to find the single core loop that proves your product — and scope a build you can launch in weeks, not quarters.
