A character profile is a working document, not a form to be completed. Its job is to make you decide things before you need them: what your protagonist fears, how she talks, what she wants and what she is wrong about. Most writers fall into one of two traps. Either they fill in a hundred fields about hair colour and favourite food and never use any of it, or they write nothing down and discover in chapter twenty that a character has changed eye colour and personality. This guide shows a middle path: which parts of a profile actually matter, how to write each so it helps the story, how to keep profiles useful as the book changes, and a worked example. The last section covers Quillen's guided character profiles.
The short answer
Start with what drives the character (a want, a fear, a flaw and an arc), then fill in only as much surface detail as the story will use. Write facts that create scenes, not trivia. In Quillen, each character has a profile with eight guided sections, from Demographics to Character Growth, and a summary view that collects everything on one page. Fill in the sections that matter to the story and leave the rest blank.
What a profile is for
A good profile does three jobs. It prevents continuity errors, so a character's age, history and appearance stay the same from chapter to chapter. It gives you decisions in advance, so when a scene needs a character to react, you already know how she would. And it exposes gaps: a protagonist whose profile shows no want, no flaw and no fear is a character who will drift. Each field you write should do at least one of these. If it does none, skip it.
Start with the engine
Before you pick hair colour, answer five questions. They are the part of a profile that produces plot:
| Question | Why it matters | Example (Wren, from Hollow Crown) |
|---|---|---|
| What does she want? | Gives her a direction in every scene | To keep her ferry and be left alone |
| What does she need? | The truth she has not accepted | To stop watching other people's journeys and make her own |
| What is she afraid of? | Creates avoidance, and so conflict | Leaving the river |
| What is her flaw? | The thing that makes her choose badly | She treats every crossing as someone else's problem |
| What is her lie? | The false belief she lives by | "The river is safe because I stay on it" |
Notice that want and need are different. The gap between them is where character arcs live: a story is the process of a character moving from what she wants to what she needs, or failing to.
Then add the surface details that earn their place
Once the engine is clear, add detail where the story will use it. The test for each fact is whether it can change a scene.
| Detail | Useful when | Skip when |
|---|---|---|
| Age | It affects what she knows, can do, or is allowed to do | Never stated and irrelevant |
| Occupation | It gives her skills, contacts and a daily setting | She has none that the plot touches |
| Appearance | A distinguishing feature the reader should hold on to | A catalogue of generic features |
| History | A past event drives a present fear or goal | Backstory that never reaches the page |
| Voice and habits | Dialogue and gesture need to be distinctive | Her speech is already clear on the page |
| Relationships | Several characters will be in scenes together | A cast of one |
Voice: the detail that pays the most
If you do only one surface detail well, make it voice. How a character speaks is the quickest way to tell characters apart on the page. Decide a few things: sentence length (clipped or flowing), vocabulary (plain, technical, archaic), verbal habits (swearing, questions, trailing off), and what she never says. A character who answers questions with questions, or who never uses a person's name, is instantly recognizable and easy to write.
Keep it alive
A profile should change as the book does. After each major draft, reread it and update: the character you planned and the character who appeared on the page are rarely identical. Note changes as decisions, with the reason. In a series, characters change from book to book, so it helps to date the notes: what is true at the start of book one and what is true at the end.
A worked example
Here is a compact profile for Wren Aldous, the ferrywoman in Hollow Crown:
| Field | Entry |
|---|---|
| Age and occupation | 27, river ferrywoman |
| Archetype | Reluctant hero |
| Want | Return the crown and free the heir |
| Internal conflict | Has never left the river |
| Arc | From watching other people cross to making her own crossing |
| Core values | Independence, loyalty |
| Turning point | Realizes the crown is a key |
Seven lines, none of them trivia. Each one points at a scene: the refusal to leave, the moment the crown becomes a key, the crossing she finally makes.
Common mistakes
| Mistake | Problem | Fix |
|---|---|---|
| Filling in every field | Time spent on details that never reach the page | Fill in what the story will use |
| No want or flaw | A character with no direction | Start with the engine |
| A flaw that is secretly a virtue | No real conflict | Give the flaw a cost |
| Appearance catalogue | Generic and forgettable | One memorable feature |
| Never updating the profile | It drifts from the book | Revise after each draft |
| Making every character a mirror of you | Samey voices | Give each a different speech pattern |
Do it in Quillen
Each character in Quillen has a guided profile in eight sections, and a summary view that collects everything on one page.
- Open your book and click Characters at the bottom of the left sidebar. Click New Character.
- Name the character. Type a name at the top. The profile has eight tabs: Demographics, Physical Appearance, History, Psychological Traits, Communication, Strengths, Weaknesses, and Abilities, Relationships and Character Growth.
- Start with Character Growth. This tab holds the engine: archetype, arc, core values, internal and external conflicts, goals, motivations, epiphanies and significant events or plot points.
- Fill in Psychological Traits and Communication for fears, habits, mannerisms and voice. These are the details that shape scenes.
- Move through the other tabs with the tabs along the top, or with the Next and Back buttons at the foot. Leave anything you do not need blank. Changes are saved automatically and a Saved indicator confirms it.
- Click Finish, then Review Summary (or View Summary) to see every section on one page, with empty fields shown as dashes.
- Click Edit to go back to the guided sections whenever you need to revise.



If your book is part of a series, characters can be linked across books so that changes carry over. See how to keep a series consistent.
