Prompts to think about
- No flaw named: a character without one has nothing to overcome.
- No arc named: decide how the character is different by the end.
- No want or need: the character has nothing driving them through the story.
Character sheet
# Unnamed character ## Role Protagonist ## Age _How old, and what does that age let them do or stop them doing?_ ## Appearance _One telling detail, not a full inventory._ ## Want _What do they pursue on the page, in concrete terms?_ ## Need _What do they lack that the story will make them face?_ ## Flaw _What habit or belief keeps getting them into trouble?_ ## Strength _What do they do well that earns the reader's sympathy?_ ## Backstory _Which single past event explains the flaw?_ ## Voice _How do they speak? One verbal tic is enough._ ## Arc _How are they different by the last page?_
Scope and limits
The checks are mechanical: they notice an empty field, a want worded identically to the need, a strength with no flaw, and a character with no arc. They say what is missing, not what is wrong.
This is a planning sheet, not a character generator — it writes no backstory and suggests no names. It does not store anything beyond this tab, so copy or download the sheet to keep it.
The character profile builder prompts a character's role, want, need, flaw, strength, backstory, voice and arc, scores how much of the sheet is answered and flags the thin spots mechanically.
What is Character Profile Builder?
The character profile builder is a sheet of prompts with a score attached. It asks ten questions about a character — role, age, appearance, what they want, what they need, their flaw, their strength, the backstory behind the flaw, how they speak, and how they are different by the last page — and reports how many are answered. The score is not a grade; it is a way to see the gaps. A character profile that has a want and a flaw but no backstory is a different kind of incomplete from one with a rich history and nothing driving them, and the open-fields list makes which one you have obvious.
The checks are the second half. They are mechanical, and they notice four specific thin spots. If the want and the need are worded identically, the tool points out that a character usually pursues one thing and lacks another — the gap between the two is what a story runs on. If there is a strength but no flaw, it notes that a strength without a flaw reads as a wish rather than a person. If no arc is named, it asks how the character is different at the end. And if there is neither a want nor a need, it says the character has nothing driving them through the story.
Those checks are prompts to think, not verdicts, and the page says so. A character can be wonderfully alive with no backstory written down, and a flaw can be implied rather than stated; the tool cannot see either of those. What it can do is make sure a field is empty because you decided it should be rather than because you skipped it, which is the failure mode a profile sheet exists to prevent.
The sheet renders as a markdown document with a heading per field, so it can live beside a scene board or a beat sheet in the same folder, and the report gathers the score, the open fields, the checks and the sheet in one copyable block. Everything runs in the browser: no account, no upload, no storage beyond the tab, and nothing is generated — the prompts ask the questions, and every answer is the writer's.
A profile is most useful when it is read alongside the draft rather than instead of it. The fields answer questions a scene asks implicitly: why this character refuses an offer, what they notice in a room, which decision they cannot make. When a scene stalls, checking the profile against it usually locates the stall at a field that is empty or contradicted — a character acting against a want they were never given, or a flaw that never shows on the page. The sheet does the remembering so the draft can be read against it, and a gap the tool flags is often the exact question the next scene has to answer.
That last point is the reason the tool is a sheet rather than a generator. A character that arrives fully written by a tool is not a character the writer knows; one arrived at by answering ten questions is. The profile builder does the asking and the bookkeeping, and leaves the imagining alone.
How to use Character Profile Builder
- Give the character a name and a role, then work through the prompts.
- Answer what you know and leave the rest; the sheet tracks what is open.
- Read the completeness score to see how much of the character is decided.
- Read the checks for the thin spots: want against need, strength without flaw, no arc.
- Copy or download the character sheet and keep it beside the draft.
When to use Character Profile Builder vs related tools
Use the character profile builder when a character needs deciding on the page and you want the questions in front of you. When the character's decisions turn into trouble, the Conflict & Resolution Planner shapes that trouble into escalating turns, and when the character carries a plot thread the Plot Point Mapper shows where it lands.
If you are working out how the character sounds, the Dialogue Practice Tool gives you a prompt to write them into.
