Custom Prompt for Janitor AI

Prompt
This character is [specific personality traits, background, and way of speaking]. Things that would be out of character: [specific things to avoid]. Real specific traits, not a broad archetype, are what make a character consistent and distinguishable.

What this does

Defines a consistent character personality and clear boundaries for character-based chat platforms.

Custom prompts for character-based chat platforms work by defining a real specific, consistent personality and setting clear boundaries for the interaction — a vague character description produces inconsistent responses, and boundaries help keep the experience within what you actually intended.

What this produces

A defined character personality built from specific real traits, a consistency check for whether responses actually hold to that established character, and a boundary-setting approach for keeping an interaction within your actual intended scope.

Variations

Three ready-to-copy versions for character-based interactions.

Character Definition Version
This character is {real specific personality traits, background, and way of speaking}. Real things that would be out of character: {specific things to avoid}.
Consistency Check Version
Here’s the character definition: {paste it}. Here’s a real response: {paste it}. Does this actually hold to the defined character, or has it drifted?
Boundary Setting Version
For this interaction, keep the actual content within {your specific intended scope, e.g. “a lighthearted adventure story” or “casual conversation”}. Setting this explicitly upfront helps keep the interaction within what you actually intended from the start.

Who this is for

Anyone setting up a defined, consistent character for interactive chat — for building a consistent professional or personal persona within ChatGPT specifically, Prompts for ChatGPT Personality covers that related, different-context approach.

Example Output

Real specific personality traits and real explicit boundaries produce a character that actually holds together consistently, rather than drifting unpredictably across a longer interaction. The consistency check catches genuine drift back toward a generic default, which is a common pattern worth checking for periodically in any longer character-based conversation.

Tips for better results

  • Give real specific personality traits, not just a broad archetype — specificity is what makes a character consistent and distinguishable.
  • Set explicit boundaries for what’s in scope, since this keeps an interaction within what you actually intended.
  • Check for consistency periodically in longer interactions, since character drift tends to happen gradually rather than all at once.
  • Be mindful of platform-specific content policies, which vary and are worth understanding before relying heavily on any character-based platform.

What didn’t work as well

A vague character description with no real specific traits or explicit boundaries produces inconsistent responses that can drift in unpredictable directions over a longer interaction. Real specific character definition and clear boundaries are what keep an interaction consistent and within your actual intended scope.

FAQ

How do I keep a character consistent over a long conversation?

Define real specific traits clearly upfront, and periodically check whether responses still hold to that definition, since drift tends to happen gradually.

Are there content policies I should be aware of?

Yes — different platforms have different real specific content policies, and it’s worth understanding your specific platform’s actual rules before relying heavily on it.

Can I use multiple characters in one setup?

This depends on your specific platform’s actual supported features — check current documentation for what’s possible in your setup.

What if responses keep drifting despite clear character definition?

Restating the key character traits partway through a long conversation can help reinforce consistency when it starts to slip.
