Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://truthgpt.gitbook.io/truthgpt-whitepaper/ai-chatbot/memberships.md). # Memberships ## Free Users By default, everyone who is interested in utilizing TruthGPT is welcome to do so, free of charge. Free members will be able to access TruthGPT, but will have ads shown on their devices and a limited number of queries per day. We recommend that who are unsure of, or simply want to try the technology, use the free version. Those who intend to use it often, whether for work or personal life, are incentivized to purchase a premium membership. ## Premium Users By upgrading to a premium membership, users will gain access to an ad-free platform, unlimited queries, custom backgrounds, chat-saving history and much more to come. The upgrade feature works in a completely decentralized manner; once a user upgrades by holding $TRUTH in their connected wallet, the address they upgraded with will become the designated premium account. Users of the mobile app will soon have the option to unlock the premium version through our in-app premium membership subscription ($12.99/month or $79.99/year). *Additional details regarding memberships will be released periodically and are subject to change without notice.* --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://truthgpt.gitbook.io/truthgpt-whitepaper/ai-chatbot/memberships.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
