Filling this in does not call AI. After you start, the draft stays in this browser tab for up to 24 hours; refreshing before starting can lose unsaved input.

A clear view of what’s ready

This is a development preview. Individual writing, version recovery, and AI rewrites are available; real-time team collaboration and live billing are still being built.

Available in this preview

The narrative Studio

Source editing, branch navigation, diagnostics, and deterministic playtesting. Save, preview, name, and restore versions, or confirm a budget for an AI rewrite.

Required before paid launch

A complete team workflow

Real-time co-editing, character and world notes, more AI templates, and Yarn / Ink exports remain in development. The 10-editor and 10MiB project targets are not validated; purchase availability is shown in workspace billing.

THE WORKFLOW AND WHAT COMES NEXT

From the first line to the final branch.

Six connected parts of Studio. Editing, playtesting, and basic exports are available; each card explains its current scope and future plans.

01 / PRODUCT VISION

Write naturally. See the structure.

Edit source text, find scenes in the branch graph, and inspect diagnostics today. Text and graph use the same story; explicitly save your changes as a new version.

02 / PRODUCT VISION

Give your world a memory.

We plan to connect characters, places, and story details through references you review. Character and world-building workflows are not available yet.

03 / PRODUCT VISION

Follow a player’s choices.

Deterministic browser playtesting is available. Follow choices, inspect paths and variables, and use diagnostics to return to scenes that need attention.

04 / PRODUCT VISION

A collaborator. You’re the author.

Rewrite selected text with Sonnet 5: review a quote, confirm a budget, then accept or reject the candidate. Acceptance changes your local draft; save it separately. Other AI templates are not available yet.

05 / PRODUCT VISION

Build the story together.

Real-time co-editing and comments are still planned. You can already preview, name, and restore saved versions, and keep a browser recovery copy of unsaved drafts.

06 / PRODUCT VISION

Take your story into production.

Export valid saved revisions as JSON IR, localization CSV, or a source package. JSON needs an engine adapter; Yarn / Ink exports are still in development.

WORKSPACE PLANS

Room for your next story.

Choose the right allowance for solo work, frequent AI use, or a shared studio.

Prices are in USD before applicable tax. Annual subscriptions charge the displayed annual total once per year; AI points are granted monthly. Review the final amount and supported payment methods at checkout.

Free personal workspaces grant 200 trial points once per verified user, valid for 30 days. Subscription points are granted monthly and do not roll over. AI usage is metered; points do not represent a fixed number of tasks. Manual writing and playtesting do not consume AI points.

Active paid workspaces may buy 3,000 points for $10, valid for 12 months without automatic renewal. Studio includes 3 editors including the owner and 20 reviewers. Additional editors cost $15/month or $150/year each, billed with Studio; they add no AI points or concurrency. After a subscription ends, top-up points pause until resubscription while their original expiry continues.
