PostBear — a month of social content from one URL
Most small businesses know they should post consistently and simply don’t have anyone whose job that is. PostBear turns one input — the business’s website URL — into a month of on-brand social content, rendered and published automatically.

Ref 01 · The problem
The problem
- Consistent social presence is a real commercial signal, but producing it is a daily creative chore with no owner in most SMEs.
- Generic AI content is worse than nothing — output has to sound like the business, grounded in what the business actually says about itself.
- Scheduling posts is easy; publishing them reliably through Meta’s APIs, with tokens, quotas and retries, is the hard part nobody sees.

What we built
From URL to brand profile
The pipeline scrapes the business site with Firecrawl and derives a brand profile — voice, offerings, audience — via LLM, with a grounding guard that constrains generation to what the source material supports rather than letting the model invent services.
A month of content, rendered properly
From the profile it plans and writes a month of posts (12–28 depending on chosen frequency) and renders carousel graphics server-side through a dedicated render service, so output is imagery, not just captions.
Real automated publishing
A scheduler publishes due posts to Facebook and Instagram through the Meta Graph API every minute, with atomic job claiming and retry classification so a flaky API call can’t double-post. Meta system-user tokens are held encrypted.
The product scaffolding
Consent flows for using a real person’s likeness in generated imagery — with an audit trail — plus subscription billing and plan quotas via Paddle, and a test suite in the hundreds keeping the pipeline honest.

What it demonstrates
- A complete AI content pipeline: ingest → understand → generate → render → publish
- Grounded generation — engineering against hallucinated marketing claims
- Production discipline around third-party APIs: idempotency, retries, encrypted credentials
