## Most critical reviews (1 lowest-rated)

### 1/5 — This is an ABSOLUTE SCAM.

*2026-03-20*

Pay for the subscription, but to use the subscription for the scan feature, it will cost you 440 credits, which means there is only one option, 1,000 credits at 39.99.  Once you attempt to use it on a file, it tells you “failed to convert the first page”, which costs you more leaves you with 280 credits (I’m not sure how that math works).  Which then sends you to the “buy more credits”, requiring, you guessed it, 1,000 more credits at 39.99.

**Developer response:** Sorry for causing trouble to you. You may encounter the problem of task failure, but the program supports retrying tasks and does not deduct new credits. If you have any questions, you can contact us by email at any time. Thank you.
