I totally agree with the Canva mention earlier. Its been a staple for me because it's just so reliable and safe compared to some of the sketchier sites out there. I've been really satisfied with how their newer AI tools handled my projects lately... no complaints at all regarding the stability. Since you're looking for cost-effective stuff, you should honestly just look at any of the free web tools from Adobe. You cant really go wrong with a brand that established. Their free features are super polished and you get that peace of mind knowing your data is actually secure. The generative stuff they offer for free works well enough for most basic design tasks without needing a full subscription. Its definitely the professional route to take if you want to avoid the headache of buggy third-party apps.
