Underline.AI

AI has a free plan that covers 5,000 AI-generated words, one seat, five Brand Voices, and more than 20 templates, plus a Chrome extension.

AI is an AI marketing platform that writes eCommerce content such as ads, blog posts, product descriptions, emails, and social media posts while keeping the copy in your brand's voice.

You can start from a template or just use the chat.

Paid plans are billed annually.

Lite is $29 a month and removes the word cap, adds unlimited Brand Voices, and raises the template count to 50 or more.

Pro is $39 a month, covers up to five seats, and lets you build your own AI templates.

It also swaps the basic editor for an advanced AI editor and docs.

Enterprise is $99 a month for teams that need more than five seats, and it comes with tailored onboarding and a dedicated account manager.

The free tier's word limit is the catch.

Anyone producing content regularly will probably hit it quickly, and Lite is the first plan without a cap.
