A one-word change changes everything.

Without LexyAi

  • You compare two versions line by line, by hand
  • A notice period going from 15 to 60 days slips by
  • You don't know if the new offer is really worth it
  • You negotiate without concrete arguments on the table

With LexyAi

  • Every change detected and classified by impact
  • Figures and deadlines before/after, clear at a glance
  • A straight verdict: sign, negotiate or reject
  • Negotiation points drafted and ready to send
