The Best AI Apps: A Step-by-Step Setup Guide
If you've decided PLEASUR AI is the best AI app for your companion needs:
Step 1: Visit pleasur.ai and sign up with email. Free, no credit card.
Step 2: Create your AI companion. Name her, define her personality in 2-3 specific sentences. "Warm and direct, asks good questions, comfortable with adult topics, has a dry sense of humor" works much better than "nice and friendly."
Step 3: Have your first conversation. Share who you are and what you're looking for. This information builds your memory foundation.
Step 4: Return daily. Memory-enabled AI apps compound in value — the relationship at week 4 is noticeably richer than day 1.
Step 5: Evaluate after two weeks. If PLEASUR AI meets your needs, consider whether the premium features add value for your specific usage pattern.
