I purchased the tier 3 license in hopes of solving a major problem, getting content out at scale to all socials at once. Marky does that and it has a lot of potential but because it is build on ChatGPT 3.5 with no option to use your own OpenAI or Anthropic API key the content outputs are subpar at best. Everything else is pretty awesome and they're on top of their roadmap but again the fatal flaw is not being able to use a higher quality AI model and being stuck with GPT 3.5 which produces cheesy low value outputs. Hopefully in the near future this changes or else I bought a dud.
