- **Category**: tool
- **Cost**: Free, no signup

## Key points

- LinkedIn renamed the Summary to About; this writes both the headline and the About
- Headline angles: who you help, proof first, short and sharp
- About opens with a hook for the ~3 lines LinkedIn shows before "see more" and ends with a next step matched to the goal
- Uses only facts you give it; missing proof comes back as [placeholders]
- Want to be seen, not just post? Commentify's Comment Agent replies to the right posts on X or LinkedIn in your voice every day, from $39/mo with a 5-day free trial
