Scope of Services

Service Provision

Heartstring ("the Platform") provides a digital tool that leverages AI technology to assist users in generating text for speeches, messages, and other written forms of personal communication ("the Services"). The Services are intended to serve as a starting point for writing and are not meant to replace professional writing or speechwriting services.


The Services are available on an "as is" and "as available" basis. The Platform does not guarantee that the Services will be uninterrupted or error-free.

User Responsibility 

Users of the Services are responsible for the final content that is used in their speeches or written communications. This includes the responsibility to review, edit, and approve any text generated by the Platform before it is used publicly or privately.

Compliance with Laws 

Users must use the Services in accordance with all applicable laws, including but not limited to, laws relating to privacy, data protection, intellectual property, and copyright.


Heartstring reserves the right to modify or discontinue, temporarily or permanently, the Services with or without notice at any time. You agree that the Platform will not be liable to you or any third party for any modification, suspension, or discontinuance of the Services.

If you choose to use the Site as a User, your relationship with Heartstring AI is limited to being an independent user, and not an employee, agent, joint venturer, or partner of Heartstring AI for any reason, and you act exclusively on your own behalf and for your own benefit, and not on behalf, or for the benefit, of Heartstring AI.

The Site may contain links to third-party websites or resources (“Third-Party Services”). Such Third-Party Services may be subject to different terms and conditions and privacy practices. Heartstring AI is not responsible or liable for the availability or accuracy of such Third-Party Services, or the content, products, or services available from such Third-Party Services. Links to such Third-Party Services are not an endorsement by Heartstring AI of such Third-Party Services.

Due to the nature of the Internet, Heartstring AI cannot guarantee the continuous and uninterrupted availability and accessibility of the Site or its services.

Data Processing

Heartstring uses a third-party artificial intelligence service, GPT, to generate the text for the Heartstrings. The information you provide is sent to GPT for this purpose.

Our website and the materials on our website are provided on an 'as is' basis. To the extent permitted by law, Heartstring AI LLC makes no warranties, expressed or implied, and hereby disclaims and negates all other warranties including, without limitation, implied warranties or conditions of merchantability, fitness for a particular purpose, or non-infringement of intellectual property, or other violation of rights.

Dispute Resolution and Arbitration Agreement

This Dispute Resolution and Arbitration Agreement shall apply if you (i) reside in the United States; or (ii) do not reside in the United States, but bring any claim against Heartstring AI in the United States.

Overview of Dispute Resolution Process. Heartstring AI is committed to participating in a consumer-friendly dispute resolution process. To that end, these Terms provide for a two-part process for individuals to whom this applies: (1) an informal negotiation directly with Heartstring AI’s customer service team, and (2) a binding arbitration administered by the American Arbitration Association (“AAA”) using its specially designed Consumer Arbitration Rules. Specifically, the process provides:

    •   Claims can be filed with AAA online (;

    •   Arbitrators must be neutral, and no party may unilaterally select an arbitrator;

    •   Arbitrators must disclose any bias, interest in the result of the arbitration or relationship with any party;

    •   Parties retain the right to seek relief in small claims court for certain claims, at their option;

    •   The initial filing fee for the consumer is capped at $200;

    •   The consumer gets to elect the hearing location and can elect to participate live, by phone, video conference, or, for claims under $25,000, by the submission of documents;

    •   The arbitrator can grant any remedy that the parties could have received in court to resolve the party’s individual claim.

Pre-Arbitration Dispute Resolution and Notification. Prior to initiating an arbitration, you and Heartstring AI each agree to notify the other party of the dispute and attempt to negotiate an informal resolution to it first. We will contact you at the email address you have provided to us; you can contact Heartstring AI’s customer service team by emailing us at [email protected], or at the contact addresses provided on the Site. If, after a good faith effort to negotiate, one of us feels the dispute has not and cannot be resolved informally, the party intending to pursue arbitration agrees to notify the other party via email before initiating the arbitration. To initiate arbitration, a claim must be filed with the AAA and the written Demand for Arbitration (available at provided to the other party, as specified in the AAA Rules.


Exceptions to Arbitration Agreement. You and Heartstring AI each agree that the following claims are exceptions to the Arbitration Agreement and will be brought in a judicial proceeding in a court of competent jurisdiction: (i) Any claim related to actual or threatened infringement, misappropriation, or violation of a party’s copyrights, trademarks, trade secrets, patents, or other intellectual property rights; (ii) Any claim seeking emergency injunctive relief based on exigent circumstances (e.g., imminent danger or commission of a crime, hacking, cyber-attack).

Arbitration Rules and Governing Law. This Arbitration Agreement evidences a transaction in interstate commerce, and thus the Federal Arbitration Act governs the interpretation and enforcement of this provision. The arbitration will be administered by AAA in accordance with the Consumer Arbitration Rules (the “AAA Rules“) then in effect, except as modified here. The AAA Rules are available at or by calling the AAA at 1–800–778–7879.

Modification to AAA Rules - Arbitration Hearing/Location. In order to make the arbitration most convenient to you, Heartstring AI agrees that any required arbitration hearing may be conducted, at your option, (a) in the county where you reside; (b) in San Francisco County; (c) in any other location to which you and Heartstring AI both agree; (d) via phone or video conference; or (e) for any claim or counterclaim under $25,000, by solely the submission of documents to the arbitrator.

Arbitrator’s Decision. The arbitrator’s decision will include the essential findings and conclusions upon which the arbitrator based the award. Judgment on the arbitration award may be entered in any court with proper jurisdiction. The arbitrator may award declaratory or injunctive relief only on an individual basis and only to the extent necessary to provide relief warranted by the claimant’s individual claim.



Severability. In the event that any portion of this Arbitration Agreement is deemed illegal or unenforceable, such provision shall be severed, and the remainder of the Arbitration Agreement shall be given full force and effect.

Changes. If Heartstring AI changes this section (“Dispute Resolution and Arbitration Agreement”) after the date you last accepted these Terms (or accepted any subsequent changes to these Terms), you may reject any such change by sending us written notice (including by email) within thirty (30) days of the date such change became effective. By rejecting any change, you are agreeing that you will arbitrate any Dispute between you and Heartstring AI in accordance with the provisions of the “Dispute Resolution and Arbitration Agreement” section as of the date you last accepted these Terms (or accepted any subsequent changes to these Terms).

Survival. This Section will survive any termination of these Terms and will continue to apply even if you stop using the Site or terminate your Heartstring AI account.

Applicable Law and Jurisdiction

You and we both consent to venue and personal jurisdiction in San Francisco, California.
