Three bio lengths from the same true facts.
A 50, 100, and 200 word professional bio built only from the facts you supply, with each claim traced to its source.
Bios get rewritten from scratch every time someone asks, usually in a hurry. They drift into job lists, adjectives nobody believes, and occasionally a credential the writer half-remembers.
Bio Writer collects your facts first and marks the gaps instead of filling them. It chooses what matters to the reader of this particular bio and writes three nested versions, then lists every claim next to the fact it came from.
What it produces.
- →A 50 word bio for programs and short forms
- →A 100 word bio for speaker pages and podcasts

Before you buy.
How is this different from just asking Claude directly?
Asked cold, Claude happily writes an impressive bio and may supply awards or phrasing you never mentioned. This Playbook uses only the facts you give it, writes nothing for the gaps, and shows you which fact backs which sentence.
How is this different from a Tool?
Playbooks are systematically produced to a fixed template and priced accordingly ($12.99). Tools are hand-built, one at a time, and go deeper ($39 to $199). A Playbook gives you a reliable method for routine work; a Tool is for when the judgment matters more than the format.
Will this work with ChatGPT, Gemini, and other LLMs?
Yes. You get a native Claude Skill (.zip) that auto-invokes in Claude, plus a plain .md you can paste into a ChatGPT Custom GPT, a Gemini system prompt, or any LLM. The procedure travels with the file.
Can I share this with my team?
It's licensed for your own personal and professional use. The output it produces is yours to circulate. To put the Playbook itself in the hands of a whole team, email hello@authority.md about team licensing.
What if it doesn't work for me?
If the file hasn't been delivered, or arrives defective or empty, we refund in full: see our refund policy.
