PERSO or a chat assistant?

Most sellers already write with ChatGPT or Claude: paste in the profile, copy the draft out, send it. The writing can be good. What stays with you is everything around it, for every prospect, every day.

Checked on 4 November 2026, against the pages listed under Sources.

Choose ChatGPT and Claude if

  • You write to a handful of people a month and are happy to do it by hand.
  • You want one assistant for everything, not only prospecting.

Choose PERSO if

  • You write to dozens of people a month and lose track of who needs a follow-up.
  • LinkedIn is part of how you reach people, not only email.
  • Your team should share one history and never write to the same person twice.
