AI SMS generator for copy that earns its place in a text thread
Abandoned cart nudges, flash sale alerts, welcome flows, and promo texts, written tight enough for one SMS segment and personal enough to sit next to messages from friends.
Free to start. No credit card.
How it works
Set your brand up once. Every generation after that is seconds.
Load the brand
Your stored voice, products, and offers give the generator everything it needs for texts that sound like you.
Pick the campaign type
Abandoned cart, flash sale, welcome, or winback, plus the offer in one line.
Copy into your SMS platform
Get tight, on-voice variants that fit one segment. Paste into Klaviyo, Postscript, Attentive, or wherever you send.
Why generic AI copy fails here
Copy Machine grounds every generation in your brand voice, website, products, and past copy. That changes what comes out.
✕SMS gives you 160 characters and zero room for warm-up
The generator writes for the segment limit from the start: offer, urgency, and link in one clean message. No 'Hi there! We wanted to reach out because...' preamble eating half your characters.
✕Texts that sound like a corporation get people unsubscribing
SMS lives between messages from actual friends, so tone matters more than any other channel. Your brand voice and emoji rules shape every text, with a casual register that still sounds like you.
✕Every SMS you send is the same discount blast, reworded
Presets for abandoned cart, back in stock, flash sale, welcome, VIP early access, and winback, each with its own psychology. Recent history context stops the repeats.
✕Compliance and clarity keep colliding with creativity
The generator keeps the offer unmissable and the CTA obvious while your voice does the work. You choose the CTA type: link click, reply keyword, or code at checkout.

Frequently asked questions
How is this different from ChatGPT for SMS?
ChatGPT pads texts with filler that blows the 160-character segment and sounds like a press release. Copy Machine writes to the segment limit, applies your brand voice and emoji rules, and uses campaign-specific psychology for cart recovery, flash sales, and winbacks. The output is paste-ready for your SMS platform.
Do I need to write prompts?
No. Choose the campaign type and CTA style from dropdowns and describe the offer in a sentence. Length discipline and voice are automatic.
Does it keep messages inside one SMS segment?
Yes, that is the default: copy is generated to fit a single 160-character segment so you are not paying for two. A character indicator shows exactly where each variant lands.
How much does it cost?
There is a free plan (25 generations a month, no credit card). The SMS generator is part of the paid plans, starting at $19/month with a free trial, so you can write your first campaign before paying anything.
