Licensing

Two licences apply to everything you publish on Incantory: the open licence you choose, which lets everyone use your work, and the service licence you give Incantory, which lets us run the site. This page explains both. The binding text is in the terms of service.

The licence you choose for everyone

When you create or fork a prompt you pick one of these licences. It applies to everyone who finds your prompt, on the site or through the API, exports and mirrors.

Licence	In one line
CC0-1.0	No conditions. Anyone may use it for anything, without credit.
CC-BY-4.0 (default)	Anyone may use and adapt it, including commercially, as long as they credit you.
CC-BY-SA-4.0	As CC-BY, and adaptations must be shared under the same licence.
MIT	A short permissive software licence; keep the copyright notice.
Apache-2.0	A permissive software licence with an explicit patent grant.

Why CC-BY-4.0 is the default: it keeps credit flowing back to you while allowing forks, remixes and commercial use, which is what a prompt library is for.

"All rights reserved" is not offered. Forking and remixing is the core of the site, so everything published here is openly licensed. If you do not want others to reuse something, do not publish it on Incantory.

Open licences are irrevocable for copies already made: if you later delete a prompt, people who copied it under CC-BY may keep using that copy under CC-BY.

Forks

• A fork records its parent, and the page shows the full attribution chain: the original source, then each fork parent, then the current author. The same chain appears in the page's structured data, the API and exports.
• Share-alike stays share-alike: a fork of a CC-BY-SA prompt must also be CC-BY-SA. The fork form enforces this.
• Attribution is kept: a fork of a CC-BY prompt keeps the chain, and you may not remove it.
• A fork of a CC0, MIT or Apache-2.0 prompt may use any licence, but must still respect the parent's own conditions (for MIT and Apache-2.0, keep their notices).

The licence you give Incantory

Separately from the licence you choose, you give Incantory a non-exclusive, worldwide, royalty-free licence to host, store, display and distribute your content through the site, API, SDKs, CLI, MCP servers, embeds, feeds, bulk exports and the mobile app, and to make the derivatives needed to do that: preview images, summaries, translations, format conversions and search indexes. This lets us run the service even for features your chosen licence might not obviously cover (for example, a machine translation of a CC-BY-SA prompt shown next to the original).

You also confirm that you have the right to publish what you submit under the licence you pick.

Bulk exports and AI crawlers

Openly licensed content (by default CC0 and CC-BY) is included in weekly bulk exports with the licence and attribution on every row, so datasets built from Incantory carry the credit with them. Our robots.txt policy for AI training crawlers follows the same licence list.

Imported content

Some prompts were imported from public open-licence collections (the sources page lists them all). Each imported prompt:

• keeps its original licence (shown as a badge) and the original copyright holder's notice;
• credits the source repository, the exact commit, the original author, and whether we modified it;
• carries the credit line the licence requires (for example, CC-BY sources).

The full text of every licence used on the site, with copyright holders and NOTICE files, is on the licences page.

Claiming imported work

If an imported prompt is yours, use "Is this yours? Claim it" on its page. If your verified GitHub account matches the source author, the claim is approved automatically: the prompt moves to your account and the attribution is kept. Other claims are reviewed by a person.

Removal requests

Authors can ask for their imported work to be removed for any reason, without a formal legal notice, using the removal request form. We honour removal requests even for CC0 content. For copyright infringement, see the copyright policy.
