The structured writing studio

Structured writing,
owned by you.

A desktop workspace for long-form writing and research — from the first idea to the finished manuscript.

Sign up for a 7-day trial — no card.

The Quarivell desktop app: project structure on the left, the manuscript in the editor, and the inspector on the right.

The process

Structure, write, research, revise, publish — in one place.

One tool that follows the work the whole way, instead of three that do not compose.

  1. 01

    Structure

    Three views over one tree. Word targets and cards.

  2. 02

    Write

    A focused editor and Compose mode. No noise.

  3. 03

    Research

    Source to citation in one click, cited to the page.

  4. 04

    Revise

    Continuity against your cards. A relationship graph.

  5. 05

    Publish

    Compile to a manuscript DOCX. Your file is never overwritten.

Three views, one tree.

Binder, Corkboard, and Outline are the same structure seen three ways. Cards and targets travel with it.

Research, inside the writing

Turn a source into a citation in one click.

Read and annotate your sources beside the draft. Ask a question about your own materials and get an answer cited to the file and the page — never an answer from nowhere.

How research works →

Grounded answer

You asked

When did the saltworks change hands?

The lease passed to the Veldt family in the spring of 1887, after the harbour court voided the prior claim.

AI, with rules

Quarivell has AI.
Quarivell is not an AI tool.

An accomplice, not an author. It works at three levels around your writing — and the words stay yours.

01

Beside the sentence

Rewrite a line in your voice and accept it as a diff. Ask about what you are writing, scoped to a selection, a chapter, or the whole project.

02

Across the work

Pull characters, places, and themes into cards. See how they connect. Draft a synopsis for a scene or a folder.

03

Through your sources

Ask about your own materials and get an answer cited to the file and the page — never an answer from nowhere.

Bring your own key, or keep it on your machine. You see what is sent. Every change is a diff you accept.Your work never trains a model.

Pricing

Buy it once. The work stays yours.

No subscription in the core. A 30-day trial of the full Pro, with no card, no watermarks, and no save gates.

The thing that pushes me off other tools every six months is that I cannot search or version my own novel. Quarivell adds structure without locking the work away.
