# What is worth paying for in an AI tool?

Original 5HO practice material. Fictional example. Reviewed 5 October 2026.

## Useful result

You'll finish with a subscription decision based on actual work and current evidence.

Pay for a capability you have tested and need often enough to justify it. “I might use it eventually” is how subscriptions acquire permanent residency. Compare the result, the limits and the exit route.

## Set up

Allow 20 minutes with current official pricing and a short trial log. Use your local currency and include tax or add-on costs where applicable. Do not assume a chat subscription includes API usage.

## Practice input

Illustrative plan: AUD 30 a month. Trial: 12 acceptable outputs, 3 rejected. Review takes 5 minutes per output. Needed feature: project files. Existing free account cannot complete that workflow within its current limits.

## Do the task

1. Identify the specific paid feature that removes the tested obstacle.
2. Calculate cost per acceptable result and include the time you spend reviewing rejected drafts.
3. Choose buy, continue testing or stay free, with a cancellation/review date.

## Prompt

Write a purchase decision record from these trial facts. Calculate subscription cost per acceptable result, list unpriced costs and say what evidence is missing. Do not invent time savings or recommend a plan by brand alone.

## Refine

Show how the decision changes if I produce only three acceptable results next month. Keep that scenario separate from the observed trial.

## Expected checks

AUD 30 divided by 12 is AUD 2.50 per acceptable output; at three outputs it is AUD 10. Neither number alone proves value, because review effort and usefulness still matter.

## Save

Save the decision, current plan link and review date. Cancel or downgrade if the paid capability stops earning its place.
