Voice DNA

An editor trained on your writing, not a house style

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.

How a round works

Calibration is a sequence of small, deliberate questions. Never a slider, never a hidden weight.

  1. Ream takes a passage from your own work and rewrites it two ways.
  2. The two versions differ on exactly one dimension — everything else is held still, so your pick means one thing.
  3. You choose A, B, or Neither.
  4. The pick writes a plain-language rule onto your style card, where you can read, edit or delete it.

Try four rounds

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.

The twelve dimensions

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.

What it does with the voice

A trained voice is not just a description sitting in a settings pane — it changes what the editors hand back.

Writes in it

Rewrite, continue and expand come back in your voice instead of the model's.

Checks for drift

Drift check flags where a passage stopped sounding like you — useful on a chapter written at 1am, or six months later.

Follows you

Voices belong to you, not to a project. Train one once and it is there in every book you start.

The honest limits

It won't draft a blank chapter in your name until it has earned it

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.

The stamp is a badge, not a gate

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.

Rules stay visible

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.

You can stop and come back

Nobody sits through twelve rounds in one go. Sessions persist and resume where you left them.
