"Disappointing waste of money" Posted 2026-03-19
Pros: Gave some interesting ideas on how to grow and build.
Was fun seeing how ai worked
Helped develop the bones of my business but Gemini can do what it can do for freeCons: Found it very hard to work on 'complex' asks like research this, provide a summary and does it meet the criteria, often not returning any results but would still charge for those non-results.
Overall: Sintra is an expensive gamble. Their "14-day refund guarantee" is incredibly misleading—it doesn't apply to additional credit purchases. Once you top up, your money is gone, even if the service fails to deliver.

On top of the rigid policy, the credit burn rate is absurdly high. Standard interactions consume credits at an alarming speed, making it a total money pit for any professional or high-volume use. You’ll hit "empty" much faster than expected and be forced into their non-refundable ecosystem. Save your money and find an alternative with transparent pricing and a fair satisfaction guarantee.
