AI support agent
Your support line runs itself.
Tell it about your business, add your policies, FAQs and price lists, and connect the tools it should check. It answers every text in seconds, day or night, in the voice you give it. A support line costs $49 a month.
Make it yours
Write how it should sound and what it should never say.
Give it your answers
Add up to 10 files: PDFs, Word docs, spreadsheets.
Let it look things up
Connect your order system or CRM, and it checks before it replies.
Example conversation. Customer: Hi, can I still return the boots I got last week? Stride Footwear: Yes. You have 30 days from delivery, and your order arrived Nov 6, so you’re covered until Dec 6. Stride Footwear: Want me to send a prepaid return label? Customer: Yes please. Stride Footwear: Done. It’s in your email now. Drop the box at any UPS store.
An example. The agent answers from your files and tools.

Questions, answered.
Is this real iMessage, or SMS with a blue coat of paint?
Every line uses real Apple hardware. On iMessage, your customers see blue bubbles, typing indicators and tapbacks. Eligible plain-text messages can use carrier SMS from the same number.
Do I need my own iPhone or Mac?
No. We run the Apple hardware and set up the number for you. You get an API token and a console; nothing to install or host.
How do I get a number?
Choose Get started to set up your number in the console. If all numbers are taken, you can join the waitlist. Pro is $49 a month, with a 30-day money-back guarantee. Cancel anytime.
Can customers reply, and do I get their replies?
Yes. Every reply and every tapback is POSTed to your webhook, signed, within a couple of seconds of landing on the phone. It shows up live in the console too, and you can read the full history through the API.
How long does integration take?
Minutes. The API is a bearer token and three endpoints: send, react, webhook. Paste the prompt from the docs into Claude Code, Cursor, or ChatGPT and it wires up the receiver, the signature check, and a test message for you.
Will my number get flagged as spam?
Not if you message people who asked to hear from you. Each line reaches out to at most 5 new contacts a day on Pro, and 25+ a day on Growth; replies and ongoing conversations don’t count toward it, up to 10,000 messages a day per number. The invite itself is two link-free texts before a link is ever sent, for the same reason. Unsolicited messaging gets a line suspended.
What if a number does get marked as spam?
It is rare. The API's rate limits are designed to keep every line out of spam filters, and across more than 10,000 messages a week we have seen it happen only twice. If it does happen, we replace the number right away at no extra charge. Your API token, webhook, and code stay exactly as they are, so your integration keeps running without changes.
Can texting people get my number banned?
Not if you follow the rules you already follow for email. The person agreed to hear from you, the offer is honest, and you stop when they ask: a text with the word STOP opts them out on every number on your account. Each number also has a limit on new people it can text (5 a day on Pro, 25+ a day on Growth), which keeps it out of spam filters.
What about consent and the law?
You need the recipient's consent, and the fines for not having it land on the sender: in the US, TCPA damages run $500 to $1,500 per message. Keep a record of who opted in, say who you are, and honor STOP immediately. The docs have a compliance section with the specifics.
How does my business name appear?
Name and photo sharing is included with Pro. Your dedicated line shares your chosen business name and contact photo through iMessage. iOS may show “Maybe: Your Company” before a recipient saves your number; the exact display depends on their device and contact settings.
Group chats, attachments, Android?
Every new signup includes SMS fallback. Your number sends eligible plain-text messages over SMS when iMessage is unavailable, including to Android phones. Photos, voice messages, videos and group chats of up to 31 people use iMessage.
Can I cancel?
Any time, from the console. If it is not for you, ask within 30 days and we refund the month in full.
