Track free trials so they never turn into charges
Use AI to build a trial tracker from your sign-up emails, with cancel-by dates and direct cancellation links.
1. Copy this prompt
Paste it into ChatGPT, Claude, Gemini or Grok (the free versions work), then replace the [highlighted brackets] with your details. Leave out account numbers and SSNs.
Here are confirmation emails for free trials I've signed up for (personal details removed): [PASTE]. Build a table with: service, trial start date, date the first charge happens, price after the trial, and how to cancel (where in the app or site). Then give me calendar reminder text for two days before each charge date, and flag any trial that says it can't be cancelled until it ends.

What to expect, and what to do if they say no
What happened when people tried it

Why this works
The problem: Free trials convert into paid subscriptions automatically, often with a single reminder or none.
How AI helps: AI can pull trial details from confirmation emails, calculate cancel-by dates (a day or two early), and draft calendar reminders.
Tools & what they cost
| Tool | Cost |
|---|---|
| ChatGPT | Free option available (Paid upgrades exist, but the free version works for this) Free tier; paid plans available |
| Claude | Free option available (Paid upgrades exist, but the free version works for this) Free tier; paid plans available |
What do these labels mean?

- Free option available Paid upgrades exist, but the free version works for this.

- Takes a cut of savings Charges a percentage of what it saves you.
- Time · Difficulty Our estimates for a typical first try, not guarantees.
- Reported What the linked source says happened, often self-reported. Your results will vary.
Watch out for
- No verified AI-specific success story yet. This is a how-to guide built on official sources.
- Free-trial offers must disclose terms clearly; report deceptive ones to the FTC (Federal Trade Commission, the federal consumer-protection agency).
- Cancelling early sometimes ends access immediately; check before you cancel.
