Content License

The Cleverbot API uses Artificial Intelligence software to provide responses to textual inputs that occur in sequence, in the form of a conversation.  These responses are here referred to as the Content.

This Agreement, and your accordance with its Terms, provides you with a license to access the Cleverbot API, but also to gather, store, alter, publish and distribute the Content in specific, limited ways. You may:

      1. Gather and store representations of the Content as complete conversations, in their original sequence, but never so as to gather or use a pool of conversational lines out of the context of their conversations;
      2. Alter or edit the words or sequences in your stored copy of the Content to an extent, but never so as to greatly change the meanings people would assign to the the Content, and never in ways that combine the Content of many conversations;
      3. Create derivative works from conversations, in the form of text, visualisations, video, sound representations and more, but never so as to create new, different conversations, and never using the Content as data or ‘training’ for any other kind of AI;
      4. Publish the original conversations or your derivative works, on the internet or elsewhere, but always with Attribution as to their Cleverbot source;
      5. Create a wrapper for the Cleverbot API, or equivalent form of code library, and publish it for others to download and use, but only if is made available for free, if it delivers every request directly to the Cleverbot API , if you clearly link to the Cleverbot API pages, and if you state that every user of it must Sign up for their own Cleverbot API Key.

In more informal terms, what the above Content License Terms 1 to 4 above mean is that you may ‘play’ with the Content to a fair extent, be creative, and come up with new formats by which Cleverbot conversations can be enjoyed, and can present the results to the general public, as long as you clearly state that Cleverbot is behind it. Examples of things you may not do include the engineering of a new bot using the Content, caching of the Content for re-use without API requests, and the building of Machine Learning models using the Content.

Subject to the terms and conditions of this Agreement, Existor grants a non-exclusive, non-sublicensable, non-transferable license to use, copy and modify the Content solely for personal or internal business purposes. No right is granted to sublicense, sell, syndicate or otherwise share the Content with any third party.

Except as expressly authorized herein, you may not publicly release or disclose data or usage statistics or other information regarding the Cleverbot API or Content. You agree to make available to Existor, upon request, usage statistics or other information regarding your access and use of the Cleverbot API.


Where or very close to any publishing of Content derived from the Cleverbot API, you agree to conspicuously display at least one of the following names textually, or their logos, in such a location and manner that your users or viewers understand the source of conversation used.  You agree also to include a web link wherever technically feasible.
