Perplexity, Cursor, Copilot: How to Build a Working AI Stack Without Getting Lost in Subscriptions

One subscription for search, another for code, a third for the IDE, a fourth for notes. At the moment of purchase, everything seems reasonable, but a month later you want a spreadsheet and a strong cup of coffee.

What to Check

• Check current pricing, cancellation policies, and availability on the service's own website.
• Verify that your card supports 3DS verification and that international online transactions are enabled.
• If the subscription is for work, decide in advance who keeps the receipts and monitors the billing date.

How to Manage Your Budget

• Open a dedicated card for AI tools and dev services.
• Set a monthly budget limit, not an emotional desire to try everything at once.
• Once a month, remove your payment details from services you no longer use.

What to Avoid

• Do not use other people's accounts or attempt to bypass the service's regional rules.
• Do not purchase access from intermediaries who ask for your password or verification codes.
• Do not make multiple repeated payments in a row after a decline; first, investigate the reason.

Conclusion

An AI stack should help your work, not turn into a scatter of forgotten payments. Tracking starts with a dedicated card and a billing calendar.

Before paying, always check the current rules of the specific service, availability in your region, and applicable legal requirements. This material is for informational purposes only.
