I purchased this plugin in Oct ’23 and it did not work as advertised, the results were extremely poor and pretty much unusable.I requested a refund several times since October 2023 without a single reply from them or any offer of assistance or a refund.I would not recommend this company or their products to anyone.

I subscribed to the 1000 credits option and purchased an additional 500 credits. I ran your plug-in in, and it was not generating any results but was taking away credits from my account. After writing your support, I received no response, so I canceled my subscription. Upon cancelation, my remaining 1000 credits from the subscription were removed from my account, followed by the removal of the additional 500 credits. This plug-in is a scam does not work, and is not supported.

I installed the app with €250.00 credit and started to add in alt tags…it ran and ran and ran. but no alt tags were added. Contacted support and nothing, nowt..zilch, nada.They have €250.00 of my money and I have nothing to show for it other than a broken app.
फ़रवरी 15, 2023
A 0-star plugin. Shouldn’t have been installed, would have been better if I have checked its review here first. It gives 10 credits for a free user even after registering with them. 10 Credit means 10 images? Who would install it?
