  3. Support by email

    Questions go straight to the business that makes the app.

Apps

The first app

Promptuoso

A prompt library that AI coding tools can call. Claude Code, Cursor and Codex reach saved prompts through MCP, on the subscription already paid for: no API key, no per-token cost.

  1. Prompts as an MCP tool

    Claude Code, Cursor and Codex search and use the library directly. The AI tool's own subscription does the work.

  2. Snippets and prompts, one library

    Text snippets and AI prompts live side by side, found with one search.

  3. One hotkey, any app

    Type an abbreviation or press the hotkey, and the text lands where the cursor is.

  4. A live XML prompt builder

    Assemble structured prompts from blocks and watch the result update as it is built.

Questions

What does buying once mean?

Each app is sold for a single payment instead of a subscription. What the licence covers is stated on the app's checkout page before anything is paid.

Which systems do the apps run on?

Windows. Each app lists the systems it supports on its own card.

What is MCP, and why does Promptuoso use it?

MCP, the Model Context Protocol, is how AI tools such as Claude Code, Cursor and Codex call outside tools. Promptuoso offers its prompt library as one, so those tools can find and use saved prompts without copy and paste.

Does Promptuoso need an AI API key?

Not for MCP. The AI tool calls Promptuoso through the subscription already paid for, and Promptuoso adds no per-token cost.

Other apps have MCP servers too. What is different?

The combination: a text expander, a prompt library and an XML prompt builder in one app, with one search and one hotkey, and the same library open to AI coding tools through MCP.

When can Promptuoso be bought?

It is not on sale yet. The price and a buy button appear on this page the day it is.

How is support handled?

By email, to the business that makes the app.
