Every AI writing tool has a voice, and it isn't yours. Ream learns yours from pages you've already written — then sharpens it by asking you to choose, one variable at a time.
Calibration is a sequence of small, deliberate questions. Never a slider, never a hidden weight.
This is calibration, working. Pick the version that sounds more like you and watch what it writes — word for word the rule the app would put on your style card. It opens on Concreteness because that is where Ream really opens: no measurement can guess at it, which makes it the least-known dimension and the first one asked. Nothing here is sent anywhere.
Which of these sounds more like you?
Every line here came from a pick you made. In Ream they are editable, and deletable, forever.
Each has declared poles, so the model never invents what to vary. The most uncertain are asked first — most writers stop early, so the early rounds have to be the informative ones.
| Dimension | One pole | The other |
|---|---|---|
| Sentence rhythm | short & punchy | longer, clause-stacked |
| Asides | em-dash | parentheses or comma clause |
| Sentence openers | And / But / So | plain subject-verb |
| Address | second person | impersonal |
| Formality | contractions | none |
| Hedging | hedged | flat assertion |
| Emphasis | italics & bold | plain |
| Paragraph length | short | developed |
| Lists vs prose | bullets | running prose |
| Concreteness | concrete example | abstract claim |
| Closing move | aphoristic snap | summary |
| Humour | dry aside | straight |
A trained voice is not just a description sitting in a settings pane — it changes what the editors hand back.
Rewrite, continue and expand come back in your voice instead of the model's.
Drift check flags where a passage stopped sounding like you — useful on a chapter written at 1am, or six months later.
Voices belong to you, not to a project. Train one once and it is there in every book you start.
There is one real gate, and it sits on the blank page. When Ream drafts a chapter from an outline — the only place it writes pages rather than edits them — it stops and offers you a few rounds first if the six core dimensions aren't done. Notes, rewrites, expansions and drift checks all use the voice from day one.
Separate thing, easily confused with the above. The label a voice carries — Calibrating, Calibrated, Strong, Excellent — unlocks nothing at any level; it reports how many dimensions have your answer on them, and that is all it does. A voice is usable at zero rounds. Calibration sharpens it.
Every pick lands in the do / avoid list on the style card, in plain language. No opaque score, no hidden weight, nothing you can't overrule.
Nobody sits through twelve rounds in one go. Sessions persist and resume where you left them.
