I need to develop a fully realized character for my story.

This character is [CHARACTER_ROLE:select:the protagonist or main character,a major supporting character,the antagonist or villain,a love interest,a mentor or guide figure,a sidekick or companion,a minor but memorable character].

Basic information I already have: [BASIC_INFO] (name, age, role in the story, any details you have decided on)

The genre and setting of my story: [GENRE_SETTING]

This character's main purpose in the story is [PURPOSE].

Themes I want this character to embody or explore: [THEMES?]

Develop this character with depth and complexity. Include their physical appearance with distinctive details, core personality traits with both strengths and flaws, their backstory and formative experiences, their deepest desires and greatest fears, their voice and how they speak, relationships and how they interact with others, their internal conflict and potential arc, secrets or contradictions that add complexity, and small habits or quirks that make them feel real. Show how their past shapes their present behavior. Identify what they want versus what they actually need. Suggest moments in a story where their true nature would be revealed.

About Character Development Builder

Flat characters kill stories. Your reader knows the villain is evil because you said so. Your protagonist makes decisions because the plot needs them to, not because their personality demands it. The character exists to serve the story instead of the story flowing from who the character is.

This prompt builds fully realized characters with depth that makes them feel like real people. Start with whatever you have in [BASIC_INFO]: a name, a role, a vague idea. The AI fills in the layers. Physical appearance with distinctive details. Core personality traits with real flaws, not cute quirks. Backstory that explains present behavior. Desires and fears that create internal conflict. A voice and speech pattern that makes dialogue distinctive without a dialogue tag.

The best part: it shows you the gap between what your character wants and what they actually need. That gap is where story happens. A character who wants revenge but needs forgiveness writes a different story than one who wants success and needs it too. Define the [GENRE_SETTING] and [PURPOSE] to get a profile shaped for your narrative. Save your character profiles in the Dock Editor and reference them while writing. Need ideas for the story itself? The story idea generator creates plot concepts with built-in character hooks. Working on their dialogue? The dialogue writer gives each character a distinct voice.

How to Use Character Development Builder

1

Set the role and basics

Choose the [CHARACTER_ROLE] and enter whatever you have in [BASIC_INFO]. Even a name and age is enough to start. "Sarah, 34, runs a bakery" gives the AI a foundation. The less you provide, the more creative freedom the AI takes.

2

Ground them in your story

Describe your [GENRE_SETTING] and the character's [PURPOSE] in the story. A mentor figure in a fantasy epic gets developed differently than a mentor in a contemporary drama. Genre shapes what details matter and what kind of backstory feels authentic.

3

Add thematic depth

In [THEMES], describe what you want this character to explore. "The cost of ambition" or "forgiveness after betrayal" gives the AI direction for internal conflicts, flaws, and character arc. Characters who embody themes carry more weight on the page.

4

Review the profile layers

The output covers appearance, personality, backstory, desires, fears, voice, relationships, internal conflict, secrets, and quirks. Read each layer and keep what resonates. Discard or modify what does not. The profile is a starting point, not a prison.

5

Test in a scene

Write a short scene with this character to see if the profile holds up. If their voice feels wrong or their motivations do not drive the action, adjust the profile. Characters reveal themselves through behavior, not description.

Who Uses Character Development Builder

Novel writers

Build protagonist, antagonist, and supporting character profiles before drafting. Having a detailed character document prevents those mid-novel moments where a character does something they would never actually do.

Screenwriters

Create characters with clear external goals and internal needs. The want-versus-need framework drives dramatic scenes. The voice and speech pattern sections help you write dialogue that actors can inhabit.

Game designers

Develop NPCs with motivations, secrets, and relationship dynamics that create meaningful player interactions. The backstory and internal conflict sections provide material for branching dialogue paths.

Dungeon masters

Build memorable NPCs quickly for tabletop campaigns. The quirks, speech patterns, and secrets sections give you enough material to improvise believably when players go off-script.
