SMS & WhatsApp Terms

Effective date: September 21, 2026.

Last revised: October 8, 2026.

Program name: Sylvie, operated by Sylvie AI, Inc.

What the program is. Sylvie is a personal executive assistant you message through SMS or WhatsApp. After you ask to join at our beta signup page and enter your mobile number, and we approve your request, Sylvie sends one introduction message and then replies to what you text: calendar help, email drafts for your review, reminders you asked for, and a daily brief you can turn off. Messages are one-to-one and about your own account. No marketing messages.

How you opt in. Enter your mobile number and choose SMS or WhatsApp on our request form. For SMS, check the unchecked consent box agreeing to receive text messages from Sylvie about your beta request and assistant activity, then select “Request beta access.” For WhatsApp, select “Request beta access” beneath the statement agreeing to receive WhatsApp messages from Sylvie about your beta request and assistant activity. The form links to these Messaging Terms, our Terms of Service and Privacy Policy. We record the time, selected channel, consent method and wording for your request. Consent to receive messages is not a condition of any purchase.

Signup verification. Before submitting your beta request, we send a one-time SMS code to the number you provide, including when you choose WhatsApp for your assistant. The signup form explains this before you request the code. Twilio Verify delivers verification codes separately from Sylvie’s assistant conversations. You can request another code after a waiting period; message and data rates may apply. Receiving a code alone does not create a beta request.

Message frequency varies with how you use Sylvie. A typical day is a handful of messages, all in reply to you or scheduled by you.

Message and data rates may apply. Check with your carrier for the terms of your plan.

To stop: reply STOP to any message. Sylvie stops all messages to that number immediately, and sends nothing further. STOPALL, UNSUBSCRIBE, CANCEL, END and QUIT work the same way. Reply START to opt back in.

For help: reply HELP to any message, or email [email protected].

Carriers are not liable for delayed or undelivered messages.

Privacy. See our Privacy Policy. Your mobile number, messaging consent and opt-out records are essential service information. Messaging providers process information needed to deliver your messages. We do not sell or share mobile numbers or consent records with third parties for their own marketing.
