I've been using Marky for 8 months and recently up-graded to the Agency package with the re-listing of Marky on Appsumo. It feels like a product in the early stages, but I find it very useful to create graphics and manage posts. I personally, do not find the AI auto creation creates posts that I want to post or submit to clients, but it does give me a basis to manually edit and create. I like the auto-animate and I have started to manually edit the animation which is very easy to use.
Overall it save time and it feels like Marky are investing in improvements which means it will only get better. I like the approvals process in the Agency platform but I would love a notifications option to alert both sides that something is ready for checking or altering.
