PostMentor
PostMentor's pitch is editing over rewriting: it keeps your own words and voice while pointing out what's weak, which suits people who already write reasonably well but want a second pair of eyes. It's LinkedIn-only and credit-limited, so heavy posters may burn through the monthly allowance quickly.
Pros
- Registered UK company (Remood Ltd.) with a verifiable address, not an anonymous product
- Selective-edit approach preserves the writer's own voice
- Includes audience-reaction simulation and post scoring
Cons
- LinkedIn only
- 100 monthly AI credits could run out for frequent posters
- No permanent free tier, only a 7-day trial
