FROM AN IDEA TO A REUSABLE CHARACTER

Practical AI character guides.

Make a useful brief, understand memory and portability, and keep observations that help you choose the controls your story needs.

CHARACTERS TO TRY

Choose a role for your next scene

Ten sourced writing partners, narrators, sandboxes and personas. See creator caveats, original opening messages and what to check in a trial.

PRIVACY & DATA

Follow the conversation data

Compare visibility, access, learning, stored copies, deletion and exports across eight platforms. Keep source dates and open questions in view.

PERSONALITY & FIRST MESSAGES

Give the traits something to do

Adapt six original characters. See how motives, observable habits, greetings and dialogue fit together, then open the complete definition in the builder.

FREE ACCESS

What can you actually do without paying?

Compare seven platforms’ free chat, creation, avatars and voice. See finite allowances, separate model costs and unresolved conditions.

MEMORY & CONTEXT

Understand what reaches the next reply

Separate written notes, recent messages, triggered lore and saved excerpts. Compare six platforms’ documented controls.

FREE WORKSHEET

Check memory with a repeatable premise

Keep the same questions, record exact replies and export observations with their conditions. No automatic platform score.

CHOOSING

Choose the platform around your character

Separate appearance, personality, saved context and model setup before making a shortlist.

PORTABILITY

Character cards, JSON, PNG and export

Understand what a file carries, which import routes are documented and what needs rebuilding.

FREE TOOL

Build a character definition you can keep

Write from scratch or use an original example. Download V2 JSON and a readable text brief in your browser.

The exercises are suggestions. Platform claims point to public sources; this edition does not claim paid-plan or long-term chat testing.
