One Subscription, 20+ AIs: How I Built AIKitPros to Replace My $55/mo AI Stack

The creator replaced a $55/month multi-tool AI stack with AIKitPros, a single API layer over 20+ AI models.

Using a Dify-based workflow plus retry, backoff, prompt mutation, and fallback models, they automated ad generation across text, image, audio, and video.

They report lowering raw per-campaign API cost to about $0.41 and cutting failure rates from roughly 20% to under 2%.

The result is less tool switching, lower spend, and more reliable content production in one unified workflow.
