Design intent
Adapt checkout to relevant known preferences while keeping all material choices visible.
When to use
Use this pattern when its control or information directly helps the current task. Start with a real user scenario rather than adding an AI-themed affordance by default.
Example
Preselect a previously used delivery option but allow easy change.
This is an illustrative Knoveya scenario, not a claim about a particular shipped product.
Implementation checklist
- Define the trigger, visible state, allowed action, and completion condition.
- Personalization cannot hide price, consent, or cancellation terms.
- Cover missing input, unavailable permissions, interrupted work, and partial results where they apply.
- Keep keyboard focus, labels, and recovery behavior understandable without motion.
Trade-offs
Extra controls or explanations add reading and decision effort. Prefer the smallest presentation that exposes the relevant consequence. Do not display a guarantee, metric, or permission that the underlying system cannot enforce.
Verify
Reproduce the example with synthetic data and deliberately trigger its failure path. Personalization cannot hide price, consent, or cancellation terms.
