Because Midjourney doesn't speak Chinese (yet)

What it does

OpenPromptStudio is a Vue-based web tool that turns Midjourney prompt engineering into a visual, card-based workflow. It translates Chinese input into English for Midjourney consumption, and displays English prompts back in Chinese so you know what obscure tags actually mean. Prompts are sorted into categories—style, quality, command, and plain text—and can be reordered, hidden, and exported as images.

The interesting bit

Instead of treating prompts as a flat string of tags, OPS structures them into a manageable database. The standout feature is Notion integration: you can manage your personal prompt dictionary inside a Notion database, complete with custom categories and aliases, and OPS syncs it locally via your own integration token.

Key highlights

• Bidirectional Chinese ↔ English translation (Tencent Translate backend for self-hosted instances)
• Prompt cards categorized by type: style, quality, command, and general
• Export your finalized prompt layout as an image
• Custom dictionaries managed through Notion databases
• Self-hostable via Node.js or Docker

Caveats

• Currently limited to Midjourney; no explicit support for Stable Diffusion, DALL-E, or other models mentioned
• Translation service requires signing up for Tencent Cloud credentials
• Notion integration setup involves manual token and database ID configuration

Verdict

Worth a look if you generate Midjourney art in Chinese and want a structured way to reuse and organize prompts. Skip it if you only work in English or need multi-model support beyond Midjourney.
