| Question | What to do | Bad sign |
|---|---|---|
| What weekly task will this solve? | Write down the exact job: research, writing, coding, files, office work, studying, planning, or normal daily chat. | You can only say that the tool seems powerful. |
| Which plan tier is enough? | Start with the cheapest tier that can handle the job, then upgrade only when limits block real work. | You jump straight to the most expensive tier without testing lower plans. |
| What is the alternative? | Compare at least one competing AI subscription and one free workflow before paying annually. | You compare only marketing pages instead of running the same task in both tools. |
| What data will you upload? | Check privacy, retention, training settings, connectors, team admin access, and export options before using sensitive material. | You upload business, customer, legal, medical, school, or financial data without checking terms. |
| How will you measure value? | Track whether the plan saved time, improved quality, reduced software overlap, or helped you finish work you would otherwise avoid. | You keep paying because cancellation feels annoying. |
| What happens if you regret it? | Save receipts, renewal dates, cancellation confirmations, app-store billing details, and support messages. | You do not know who billed you or where refunds are handled. |
Buyer audit
Before you pay, prove the subscription has a job.
A paid AI plan should survive a basic audit: normal daily use, one serious task, limits, privacy, billing, and whether another tool already solves the same job.
Normal-use proof
Name three ordinary tasks you will use this for this week. If you cannot, a free plan or monthly test is safer.
Serious-task proof
Run one real work item through the tool: a document, report, coding issue, research question, presentation, or business task.
Limit proof
Check message caps, model access, file uploads, research limits, image or voice limits, and whether the plan changes by region.
Privacy proof
Know whether chats, files, connectors, or team content can be used for training, retained, exported, deleted, or seen by admins.
Billing proof
Find the renewal date, cancellation route, app-store billing path, invoice method, tax, refund policy, and annual-plan terms.
Overlap proof
If you already pay for another AI subscription, decide whether the new plan replaces it, complements it, or just duplicates it.
