What it does

A document template builder, built for the AI era

Design once, generate many. NxtDocument Studio is an AI document blueprint generator — the structured spec your LLM workflows have been missing.

Structured Sections

Define reusable sections, ordering, fields, and required content for every document type.

QC Checklists

Encode quality rules with severity — low, medium, high, critical — so AI outputs can be auto-validated.

Reference Requirements

Specify supporting URLs, documents, datasets, or images expected with each blueprint.

Output Schemas

Pick JSON, Markdown, or docx-ready output and toggle metadata, references, and QC blocks.

Export Anywhere

Download as versioned JSON or polished Markdown. Plug into any LLM pipeline.

100% Local

No accounts, no servers. Everything runs in your browser via localStorage.

Who it is for

For teams that want consistent, AI-ready docs

From engineering to compliance, NxtDocument Studio gives every team a shared specification language for their documents.

AI / ML Engineers

Blueprints become prompts and JSON schemas your agents can target.

Product Managers

PRD and roadmap blueprints your whole org follows.

Engineering Leaders

Technical spec, RFC, and incident report standards in one place.

Compliance & Ops

Policy, SOP, and audit blueprints with enforceable QC rules.

Open source

Built in the open. Yours forever.

MIT licensed and community-driven. Fork it, self-host it, contribute back.

MIT licensed

Use commercially, modify freely, no strings attached.

Community templates

Share blueprints with the community — or keep them private.

Self-hostable

Static site. Drop it on Cloudflare Pages, Vercel, or your own server.

No vendor lock-in

Standard JSON + Markdown exports work with any tool.

Privacy-first

Your data never leaves your browser

Local-first by design

Every blueprint is stored in your browser via localStorage. The Studio works fully offline after first load. No telemetry. No cookies. No account.

  • No backend — nothing to send, nothing to leak
  • Works offline once the page is loaded
  • Export and self-host in your own repo
  • Inspect every line of the source on GitHub

AI-ready, on your terms

Export blueprints as structured JSON to feed any LLM. Or render them as Markdown for human review. You decide what — if anything — goes to a model.

Versioned, portable, AI-ready

Every export is wrapped in a typed envelope so downstream tools know exactly what they're consuming.

Human-readable doc with front-matter, sections table, QC checklist, and reference requirements.

Docx-ready

Markdown shaped for Word import — preserve structure when sharing with non-technical reviewers.
