Heuristics still matter more than ever with AI

Published 18 September 2026 · Source dated 9 September 2026

AI tools can generate screens fast, but they don't validate usability — that's still on you. Classic heuristic evaluation is more relevant, not less, now that production speed has gone up.

As AI-assisted design and prototyping tools speed up how fast screens get made, the actual usability checking hasn't gotten any faster or more automatic — an AI agent can generate ten versions of a flow in minutes, but none of them are tested. Research-backed methods like heuristic evaluation and short usability tests are the counterweight: cheap, quick, and they catch the stuff AI-generated UI quietly gets wrong (unclear error states, inconsistent feedback, poor recoverability). This isn't new advice, but it's newly urgent given how much more UI juniors are now shipping per week. Label: **established** — the method itself is decades old and well evidenced, just newly relevant.

Coach

before you ship your next AI-assisted screen, run a quick 10-point heuristic check against it and write down what fails.
