Bought this tonight on tier two and have run one conversation to reply to an email and made just eight pictures to compare previous work on Abacus. ai and MachineArt - the latter which I got previously on AppSumo. Just this has ripped though nearly 997 of the 12,000 credits (remaining 11003 = 8.31% used). Seems very heavy compared to the other two where I never go beyond 100 of my 1000 allocation in MachineArt and comparative 2% on sessions in Abacus and that's being generous to Merlin. Of the eight pics, maybe five were useable. Equal quality to Flux through Abacus.ai, better than MachineArt on less tries but still not comparable given the credit takeup.
Open to any feedback to reduce the credit drain, otherwise not going to be of much practical use or reliability to me as would be used up in one days research and work.
In settings, you can only choose US "English". (I know I can tell it to be British and moan a bit more 👀).
Once you are logged in it also has heavy marketing to subscribe to a monthly/yearly plan for unlimited use before that is given as my answer, so feels a bit disingenuous.
