FableNode development preview: what is available

FableNode is being built for game writers and narrative teams, connecting scripts, branching stories, and project management. This website is a development preview.

Updated September 26, 2026.

Current preview

You can try email sign-in, workspaces, and project management. Studio provides source editing, branch navigation, diagnostics, and deterministic browser playtesting. Explicitly saving stores a private source revision. Projects and workspaces require authorized access and are not published as blog articles. The homepage Studio illustration remains a concept; open your workspace to use the actual editor.

The history panel lets you preview, name, and restore saved versions. Unsaved drafts can have a recovery copy in this browser for you to review and restore when reopening a project. This is separate from cloud saving and can be lost if browser data is cleared or storage is unavailable; keep an independent backup.

Valid saved revisions can be exported as JSON IR, a source package, and localization CSV. JSON IR needs an engine adapter and is not a ready-to-run game project. A concurrent save conflict preserves your local draft so you can review the remote revision before deciding what to do.

Selected-text AI rewrites

Sonnet 5 is connected in the current preview. Save your source, select the text to rewrite, review a quote, and confirm a credit budget before running the task. Preview the candidate and accept or reject it. Acceptance changes only the local draft, which you still need to save; the model does not directly overwrite your cloud source.

AI credits are metered by actual usage, not a fixed number of tasks. Free personal workspaces grant 200 trial credits once per user after email verification, valid for 30 days with no monthly reset. Manual editing and playtesting do not consume AI credits. The other five planned AI templates are not available yet.

Billing test scope

Workspace billing currently offers monthly subscriptions and credit top-ups only in the Stripe sandbox. No real payments are collected. Annual plans and extra-seat purchases are not available, and the pricing page’s paid prices and capacities describe launch plans.

Still in development

Real-time co-editing, character and world-building workflows, and Yarn / Ink exports are still in development. The 10-editor and 10MiB project targets have not been validated. A planned feature shown on the website is not a claim that it is available.

Data and service providers

Supabase provides sign-in and the business database. Cloudflare provides website infrastructure and private R2 storage for saved source. Confirmed AI rewrites send the selected text and rewrite instructions for model processing. Read the privacy notice and preview use notice for the current scope. Keep your own copy of your work and use content suitable for testing.
