Headless AI document editor

Your document editor, bring your own AI.

wordspace is a clean, native document editor with no AI inside. Copy one prompt, paste it into Claude Code, Cursor, or any agent, and let your AI edit the open document through a secure local REST API. Every change auto-saves to your .wsp file and refreshes instantly through WebSocket.

A simple editor. An AI-shaped hole.

No AI inside

wordspace has no built-in model. You keep full control of the prompt, model, and tooling. Use Claude Code, Cursor, or your own agent — swap anytime without migrating documents.

Copy Prompt bridges it

One click copies a ready-to-paste prompt with the local API base URL and your key. Paste into your AI tool and it immediately knows how to read and write your open document.

.wsp files, auto-saved, live-synced

Every AI edit persists to a native .wsp file on disk. WebSocket pushes changes back into the editor instantly, so you and the AI always see the same state.

How it works

Three steps. One prompt. Any AI tool.

Click Copy Prompt
The toolbar button copies a connection prompt — base URL and API key — to your clipboard. Nothing leaves your machine.
Paste into your AI
Drop it into Claude Code, Cursor, or any agent that can call HTTP APIs. Your AI now knows how to read and edit the open document.
Watch it edit live
The AI calls the local API. Every change auto-saves to your .wsp file. The editor re-renders instantly through WebSocket.

Copy Prompt — illustrativeExample

You are connected to a wordspace document.

Base URL: http://127.0.0.1:3000
API Key:  ws_live_••••••••••••••••

Read / write the currently open document:
  GET  /api/doc             → { content, pageSize, filePath, ... }
  PUT  /api/doc             → partial update, auto-saved to .wsp
  POST /api/wsp/create      → create a new .wsp in ~/Documents/Wordspace/
  POST /api/files/open      → open a .wsp by path

All writes persist to disk. The user sees every edit in real time.

Frequently asked

Do I need my own AI account?

Yes. wordspace has no built-in model — you bring the AI. Most people use Claude Code, Cursor, or another agent they already pay for. That also means no wordspace subscription for AI tokens.

Which AI tools are supported?

Anything that can call an HTTP API. That includes Claude Code, Cursor, Windsurf, and custom agents built on the Anthropic, OpenAI, or any OpenAI-compatible SDK. The Copy Prompt output works the same way for all of them.

What is a .wsp file?

wordspace’s native document format. Currently a JSON file that captures content, page format, and editing context. In the future it will evolve into a folder-based package so AI collaboration history travels with the document.

How does the app update itself?

wordspace checks for new versions on startup. Downloads are published through wordspace.ai/downloads/mac and wordspace.ai/downloads/win, which always point at the latest build in our public release mirror on GitHub.
