The most common overpay is not a subtle one. It is paying the top tier because it is the top tier, or paying for two tools that do the same job. Both scenarios in this lesson are exactly that, and both fixes take five minutes.
Scenario 1: the solo writer on ChatGPT Pro
Dana writes newsletters and client copy, sends perhaps 30 to 40 messages a day, mostly drafts and rewrites, never uploads video, never runs anything for an hour. She is on ChatGPT Pro at $200 a month because "it has the best model and no limits". Which plan should she be on?
Which would you trust?
Which is the cheapest plan that still does Dana's job?
Scenario 2: the student paying for two $20 plans
| What Sam does | ChatGPT Plus $20 | Claude Pro $20 | Free tier of either |
|---|---|---|---|
| Study notes from pasted chapters | Yes | Yes | Yes |
| Practice questions | Yes | Yes | Yes |
| Essay feedback on a 2,000-word draft | Yes | Yes | Usually yes; check the current upload limit |
| Monthly cost | $20 | $20 | $0 |
| Yearly cost of both | $480 for two tools doing one job |
Verdict: keep one paid plan and use the other vendor's free tier. Every task in the table runs on either. Sam prefers Claude's writing feedback, so: Claude Pro at $20 plus ChatGPT Free at $0. Saving $20 a month, $240 a year, with no change to what gets done. If Sam only hits a cap at exam time, even the remaining $20 is worth a look: two months of Plus a year costs $40, not $240.
