Running it, start to finish
- Provide real samples and define three or four content pillars.
- Check the flagged claims on every draft.
- Keep a person in the publishing loop.
What you get back
The output this produces, every time.
- Derives your voice from real posts and bans the AI tells and engagement-bait openers.
- Writes natively per platform rather than reformatting one post, which is visible when done.
- Forbids invented statistics, customers and testimonials, which is the reputational risk.
Getting better results
Where this usually goes wrong, and how to avoid it.
- Supply posts that actually sounded like you. Including ones that performed badly. The voice is what matters here, not the performance.
- Keep the pillars tight. Without them an agent drifts into generic motivational content, which is what most automated accounts become.
- Verify every claim before posting. The output flags which claims need checking. An invented statistic on a public account is hard to walk back.
