Echoic

Philippine brands need a steady stream of on-brand posts across Facebook, Instagram and TikTok, written in the way their customers actually talk. A single model call produces generic copy and images that drift from the brand.

I architected Echoic's content pipeline as a chain of specialised model steps instead of one prompt:

• Crawl the brand's site, then Gemini extracts brand context and asks intake questions.
• Gemini plans the campaign and writes captions and hashtags per post.
• A slide planner lays out each carousel, and an OpenAI critic reviews the plan before anything renders.
• Gemini image models render every aspect ratio, followed by text-fidelity checks, logo compositing and brand tinting.
• Dispatchers publish to each platform, with usage and cost tracked per model call.

Around the pipeline: subscriptions, credits and paid-feature gating through PayMongo and Stripe.

Echoic runs in production at echoic.symph.ai. The screens here are the real interface running on sample data for a fictional coffee brand.
