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.
3. Tier limits¶
| Limit | Free | Pro |
|---|---|---|
| Private Prompts | 5 | Unlimited |
| Private Personas | 5 | Unlimited |
| Private Tones | 5 | Unlimited |
| Private Outputs | 5 | Unlimited |
| Private Constraints | 5 | Unlimited |
| Private Tone Collections | 5 | Unlimited |
| Private Constraint Collections | 5 | Unlimited |
| Private Libraries | 0 | Unlimited |
| Versions per prompt | 3 | Unlimited |
| Favorites per entity type | 5 | Unlimited |
| Favorited Tone Collections | 5 | Unlimited |
| Favorited Constraint Collections | 5 | Unlimited |
| AI improvements per month | 50 | 250 |
| API keys | 1 | 25 |
| API requests per day | 20 | 1,000 |
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:
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.
