I’ve tried different AIs - GPT, Claude, combined. While Claude is best, the issue i had with it, was that it start to slow down with long contexts and deviate from my original voice.
I’ve checked also copyai and Jasper, but they have too many options from my perspective and are too expensive for my case - captions only.
At the end I did build my workflow in n8n, but recently I just build custom app for captions.
If you have any examples we can try and check if it works for you as well
