When to Switch Personas

During a Conversation

You might start with Companion for general discussion, then switch to:
  • Coding Expert when you hit a technical problem
  • Brutally Honest when you need a reality check
  • Writer when drafting content

For Different Projects

Some projects benefit from specific personas:
  • Technical projects: Coding Expert
  • Creative projects: Writer
  • Learning projects: Patient Teacher

Based on Feedback Needs

  • Need encouragement: Companion or Patient Teacher
  • Need hard truths: Brutally Honest
  • Need efficiency: Executive Assistant

Persona and Memory

Your memories work with all personas. Switching personas does not affect what Flast remembers about you. The same Always memories are included regardless of which persona you use.

Experimenting with Personas

Try asking the same question to different personas. You will get different perspectives:
  • Companion might explore implications
  • Brutally Honest might point out flaws
  • Coding Expert might focus on implementation
  • Patient Teacher might break it into steps
This can help you see a problem from multiple angles.
If you find yourself switching personas frequently, consider whether your default should change. The right default reduces friction.
