Tiers & Access

Prompty.tools is free to use. Paid tiers remove limits and unlock higher-volume access. This page lists the exact numbers and explains how the browser extension and API fit into the picture.

1. Subscription tiers

Prompty.tools has two subscription tiers.

• Free - included with every account. Full access to the builder, voting, favorites, and community content. Tier limits apply to private items, versions per prompt, AI improvements, and API usage. Free accounts cannot create private libraries; libraries on Free are public-only.
• Pro - 4.99 EUR per month. Removes the private-item and versioning caps, unlocks private libraries, and raises the AI-improvement and API quotas.

See the full comparison and upgrade options on the pricing page. Every paid plan starts with a 30-day free trial for first-time subscribers.

2. What counts toward your limits

Only private items count toward your tier limits. Public items are unlimited on every tier. If you want to build freely without hitting a wall, keep your work public.

The items that count are: private Prompts, private Personas, private Tones, private Outputs, private Constraints, private Tone Collections, private Constraint Collections, and private Libraries. Favorites count toward a separate per-entity-type limit. Versions per prompt and AI improvements are counted independently.

Queues are always private — there is no public/private toggle. Your total queue count and the number of pending items per queue are each tracked against their own separate limits.

Libraries on Free

Libraries are a Pro feature when private. On Free you can still create libraries, but every library you create must be public. If you need a private library, upgrade to Pro.

4. AI improvements

The Improve button rewrites your text with AI. It is available wherever you create or edit content in Prompty.tools:

• Task section in the builder: rewrites your task for clarity.
• Prompt section in the builder: improves the compiled prompt as a whole.
• Persona create/edit forms and detail pages: improves the title and description.
• Tone create/edit forms and detail pages: improves the label.
• Output create/edit forms and detail pages: improves the label.
• Constraint create/edit forms and detail pages: improves the text.

There is also an AI persona generator. Instead of writing a persona from scratch, describe the role you need in plain language (up to 300 characters) and Prompty.tools generates a structured title and description for you. This counts as one improvement toward your monthly quota.

If the text is already clean and no improvement is needed, Prompty.tools shows a notification instead of consuming a use.

• Each use (improve or generate) counts as one improvement toward your monthly quota.
• The quota resets monthly.
• Free plans receive 50 improvements per month. Pro raises this to 250.
• An Undo button reverts the most recent improvement if you do not like the result.
• AI actions are also subject to a short-window rate limit to keep things responsive for everyone. If you trigger too many improvements in quick succession, Prompty.tools will ask you to slow down before the next call. The monthly quota is unaffected.

5. Browser extension

The Prompty.tools browser extension puts your library in a popup that sits alongside any AI chat tool. Open it, find the prompt or persona you want, and copy it to your clipboard in one click. Paste it wherever you need it.

• Browse your saved prompts and personas, or the public community library.
• Search, sort, and paginate - the same controls as on the dashboard.
• Copy the compiled prompt to your clipboard with a single click, then paste into ChatGPT, Claude, Gemini, or any other tool.
• Recent items - the extension remembers what you used most recently and surfaces it first.

Install the extension from your browser's store:

• Install for Chrome
• Install for Firefox

6. API access

Prompty.tools has a REST API for programmatic access to your library. You can read, create, update, and delete your prompts and building blocks from any code that can make an HTTP request.

• Authentication - every request carries a Bearer token tied to an API key you generate.
• Base path - all endpoints live under /api/v1.
• Rate limits - each key is bounded by your tier's daily request limit. See the Tier Limits table above.
• Scope - the API gives you access to your own items and to public items. It does not expose other users' private data.

This page covers the conceptual picture. For the full endpoint-by-endpoint reference, see the API documentation site. The raw OpenAPI specification is also served at /api/v1/openapi if you need to generate a client.

7. API keys

API keys are created and managed at /dashboard/api-keys. Each key has a name and a short prefix you can use to identify it in lists. The full key is only shown once, when you create it, so store it in a safe place immediately.

• Create keys up to your tier's maximum (1 on Free, 25 on Pro).
• Rotate a key by creating a new one and revoking the old one after you have updated your client.
• Revoke a key at any time. Revoked keys reject every subsequent request.

Treat keys like passwords

A key grants full access to your account's API. Do not commit keys to source control, do not paste them into chat logs, and rotate them promptly if you suspect exposure.

8. Analytics and data collection

Prompty.tools uses a combination of third-party analytics tools and its own first-party event system to understand how the platform is used. None of the mechanisms described here use advertising or tracking cookies.

Performance monitoring — Vercel Speed Insights

Vercel Speed Insights measures Core Web Vitals (page load time, interactivity, visual stability) from real browser sessions. The data is aggregated and anonymized. No personal data is collected or stored.

Page analytics — Vercel Web Analytics

Vercel Web Analytics counts page views and unique visitor sessions without cookies or cross-site tracking. No personal data is collected.

First-party usage events

Prompty.tools records a small set of in-product interaction events to measure how the platform is used in aggregate.

Event	Triggered when
Prompt copied	You click Copy in the Prompt section of the builder
Prompt saved	You save a prompt to your library
Signup clicked	You click Get started or Create your free account on the landing page

Key properties of this system:

• Cookieless. No cookie is set or read.
• No personal identification for anonymous visitors. If you are not signed in, your IP address is used temporarily to enforce the rate limit but is never stored in the event record. The event is saved with no user identity attached.
• Rate limited. The system accepts up to 30 events per day for signed-in users and 10 per day for anonymous visitors.
• Aggregate-only access. Event counts are visible only to administrators. There is no user-accessible view that exposes individual event records.

For the full privacy disclosure, including your rights under GDPR and CCPA, see the Privacy Policy.

9. MCP server

Prompty.tools publishes an official Model Context Protocol (MCP) server — @prompty-tools/mcp — that lets any MCP-compatible AI client read and use your prompt library directly, without manual copying and pasting.

What it does

The MCP server exposes your Prompty library over the Model Context Protocol. Once configured, MCP-aware clients can call it as a tool source:

• 33 tools covering the full range of library operations: search, read, create, and update prompts, personas, tones, output formats, constraints, and libraries.
• 6 resources representing the main entity collections, readable as structured context by the client.

Changes you make to your library on prompty.tools are reflected immediately. Update a prompt once, and every connected MCP client sees the new version on its next call — there is nothing to redeploy.

Supported clients

Any client that implements the Model Context Protocol can connect. That includes Claude Desktop, Cursor, and other MCP-aware tools. The configuration is a few lines of JSON in the client's settings file.

Setup

The server runs via npx. Add the following to your MCP client's configuration:

{
  "mcpServers": {
    "prompty": {
      "command": "npx",
      "args": ["-y", "@prompty-tools/mcp"],
      "env": { "PROMPTY_API_KEY": "pk_..." }
    }
  }
}

Replace pk_... with an API key from your dashboard. See section 7 for how to generate one.

Authentication and access rules

The MCP server uses the same authentication as the REST API: every request is scoped to the API key you provide. Visibility and ownership rules are enforced server-side, so the MCP server cannot access other users' private data. The daily API request limit from your tier applies to MCP calls as well.
