Stop guessing. Start engineering.

Prompty gives you the building blocks to craft precise, repeatable prompts that get better results from any AI model — every single time.

Features

Everything you need to master AI prompts

Structured prompt builder

Break down prompts into task, persona, tone, output format, and constraints. Never miss a component again.

Community-powered

Browse, favorite, and vote on personas, tones, outputs, constraints, and libraries shared by other prompt engineers.

Version history

Every change to your building blocks is tracked. Roll back, compare, and evolve your prompts over time.

Save and organize

Save complete prompts and individual building blocks to your dashboard. Find them instantly when you need them.

How it works

From blank page to perfect prompt in 60 seconds

1

Define your task

Describe what you want the AI to do. Be as specific or general as you like.

2

Add building blocks

Choose a persona, set the tone, pick an output format, and add constraints to guide the AI.

3

Copy your prompt

Your engineered prompt is assembled automatically. Copy it and paste it into any AI platform.

Libraries

Curate, share, and showcase your best prompts

Group related prompts into a library. Keep it private for your team, or publish it so others can vote, favorite, and learn from it.

  • Group prompts by theme
    Pull together your customer support prompts, your coding prompts, or your writing starters into one curated space.
  • Public or private
    Publish a library and get a shareable link, embed code, and a spot on your public profile. Or keep it just for you.
  • Community feedback
    Public libraries can be upvoted, favorited, and commented on. See which prompt sets resonate.
  • One click from any prompt
    Add a prompt to a library directly from its detail page. Create a new library in the same flow.

API

Your prompt library, fully programmable

Access every prompt and building block through a REST API. Automate workflows, power AI agents, or integrate with your own toolchain.

GET /api/v1/prompts
// Fetch your prompts
const res = await fetch(
"https://prompty.tools/api/v1/prompts",
{ headers: { Authorization: "Bearer sk_..." } }
);
  • API key authentication
    Generate keys from your dashboard. Scoped per-user, revocable at any time.
  • RESTful endpoints for every entity
    Full CRUD for prompts, libraries, personas, tones, outputs, constraints, and collections.
  • Build on top of your library
    Fetch prompts at runtime, power AI agents, or sync with your own tools.
  • Same access control
    The API respects visibility and ownership rules, just like the dashboard.

NPM Package

Fetch your prompts from any JavaScript app

Install @prompty-tools/core and pull prompts, personas, and building blocks with a single typed function call. Works in Node, Next.js, and the browser.

@prompty-tools/core
# Install
npm install @prompty-tools/core
// Fetch a prompt
import { Prompty } from "@prompty-tools/core";
const client = new Prompty(apiKey);
const prompt = await client.prompts.get(id);
  • Typed client
    TypeScript-first with auto-complete across every endpoint. Catch mistakes before they ship.
  • One-line fetch
    Grab a prompt by ID with a single function call. No manual URL building, no fetch boilerplate.
  • Node and browser
    Works in Next.js, server scripts, Vite apps, and edge runtimes. Ship it wherever your code runs.
  • Your API key, your access rules
    Same scoping as the REST API. Visibility and ownership enforced server-side.

Roadmap

And we're just getting started

Sign up today and be the first to access these upcoming features.

Webhooks

PLANNED

Get notified when your prompts or building blocks are updated. Integrate prompt management into your existing workflows.

Prompt testing suite

PLANNED

Test a single prompt against multiple models side by side. Compare outputs, measure quality, and find the best model for each task.

MCP server

PLANNED

Expose your Prompty library over the Model Context Protocol. Hook it into any MCP-aware client and fetch prompts as tool context.

Claude Code plugin

PLANNED

Pull prompts and personas straight into Claude Code. Use your Prompty library as context without leaving the terminal.
