PaCo (Page & Company) is a digital marketing and content creation agent that runs a small business page's weekly content operation end to end.

I built it for a problem I know from my own freelance work. SME owners need a steady week of on-brand posts, but they have no marketing team, and general AI writing tools hand back unchecked, off-brand drafts the owner must still fix one by one.

PaCo is organised like a small marketing company, not a single chatbot. A CEO orchestrator takes one brief and routes it through two departments and six roles: a Strategist researches trends (every item keeps its source link) and writes the 7-day plan; a Copywriter drafts in the brand's own voice; a Graphic Designer renders visuals in two styles (a poster system, and conceptual ads built on a single visual metaphor) and produces real vertical MP4s for short video posts, each directed by Muse Wonder in six beats (hook, pain, reveal, demo, honest proof, call to action); a Brand Checker tests each draft; a Scheduler queues approved posts through Postiz; and a Performance Analyst writes the weekly report (goal, strategy, execution, result).

PaCo carries the rest of the marketing staircase. A Brand Builder walks a new brand through five levels (identity, audience, positioning, offer, customer journey), each drafted for owner approval, then written into the brand data. A Business Research step extracts sourced claims and records an explicit gap for uncovered ground, so silence never masquerades as evidence. Approved posts are adapted into per-platform variants (Facebook, Instagram, TikTok, Threads, X), each humanised and checked against that platform's caps. The Analyst runs four instruments, not one: the performance report, a visibility audit (SEO, GEO, AEO), a content analysis, and an audience analysis; all four feed the Strategist, so next week's plan starts from last week's evidence. A heartbeat schedule can run the cycle alone and stop at the approval gate with a notification; retrieval memory feeds the planner the brand's relevant past work; insights pull from the Facebook Graph API; the store runs on SQLite, migrated from the file store and verified row for row.

Checking is split in two, which keeps it trustworthy: a deterministic rule checker (banned phrases, call to action, platform length caps, required hashtags) that quotes the draft's own lines as evidence, and an independent model judge. A failing draft gets one automatic revision, then it is flagged for a human rather than quietly passed. The approval gate is enforced in code: nothing reaches the scheduler unapproved, and a refusal test proves it.

The demo brand is FYF AI, my own AI-automation services page for Myanmar SME owners. PaCo was built entirely during the event window. It completed ten full real runs, each a week of FYF AI content (7 posts), every draft checked and judged in a dedicated pass, every run ending at my approval gate. The codebase carries 323 automated tests, all passing.
