Staff drops a WeChat photo → AI writes captions → owner approves → publishes to 4 platforms in one click

A multi-store Australian car-modification chain. Marketing relied on the owner personally writing captions and asking staff to post to IG / FB / TikTok / Xiaohongshu Overseas. 4 platforms × 4 captions per post. They could push 1 post a day max. We built a WeChat-group-driven AI content factory — staff drops the photo, owner approves once, all 4 platforms publish.

About the Client

A multi-store Australian car-mod chain serving Chinese and local enthusiasts — 3 stores in Sydney, Melbourne, Brisbane, working on Japanese and European builds. 70% of leads come from social: IG for static, FB for community, TikTok for motion, Xiaohongshu Overseas for seeding. Content volume = revenue.

Their Challenge

Why ManifoldX

The owner had quoted two local digital marketing agencies at $4K–8K/month, but they didn't understand the car-modification vertical — captions read like generic 'premium quality' filler. We sampled the owner's own writing style, distilled it into prompts, AI writes close to his voice, owner just signs off the final draft.

The Solution

1. WeChat group entry — staff snap to upload

Each store has a WeChat work group. Staff drop photos in with one casual line of context ('Just installed HKS intake on a customer's GTR, looks insane'). The bot picks it up automatically.

2. AI content generation — 4 platforms × 3 languages in one shot

OpenAI vision model identifies the car first (model, colour, mod parts, scene), then calls the owner's 'style prompt' to write platform-specific captions:

3. Owner approval — one-click in WeChat

All drafts bundle into a review card pushed to the owner's WeChat. The card contains: previews for all 4 platforms + bot's 'priority tier' (A = post now / B = regular / C = backup). Owner taps Approve or Rewrite. Tweaks via voice memo, AI rewrites.

4. One-click multi-platform publishing

Once approved, the bot publishes via IG / FB Graph APIs directly; TikTok schedules via Buffer; Xiaohongshu Overseas runs through Notion → semi-auto (no public API, but staff just hits Publish — captions and images pre-filled).

Working with us

Week 1: collected 100 posts the owner had written over the past year, distilled into a style prompt template. Weeks 2–3: AI generation + approval flow. Weeks 4–5: hooked into 4 platform publishing APIs. Week 6: ran live for a week with content from all 3 stores. Client provided one store manager as point of contact, 1 hr weekly sync.

I used to write captions every day, and the worst part was rewriting the same content 4 times in 4 voices. Now AI writes, I glance, 95% goes through unchanged. The time freed up actually goes back to being in the shop talking to customers. — Client owner (paraphrased from client interview)

Impact

What's next

Q3: video post-production module (staff shoots 60s raw, AI auto-edits to 15s TikTok with bilingual subs). Q4: client-side request flow (customer DMs the bot from IG, enters lead pipeline). The 'content factory' template will be abstracted for other visually-heavy verticals (F&B / nail salons / fitness studios).
