Frequently asked questions
Can I use this for a LinkedIn bio?
Yes. Use the short or long length, then paste it into LinkedIn and adjust for your exact headline or about-section style.
Does it invent credentials?
No. The tool only works from the proof and credibility details you enter. Leave that field blank if you do not want a proof sentence.
Which person should I choose?
Third person is common for bylines and speaker pages; first person feels more natural for personal websites and social profiles.
