Hooks
A first line that stops the scroll
Every post opens with a hook. When a post matters, ask for several and pick the one you like. The rest of the caption keeps one call to action.

Written for the place it is posted
Instagram, LinkedIn, X, YouTube and Google each need a different length and style. A Google Business update leads with the offer, carries one button and keeps the phone number out of the text.

What it writes
All the words your marketing needs
Every draft uses facts from your brand kit and waits for your approval.
Hooks and captions
A strong first line and a clear caption for every platform you post on.
Hashtags and keywords
Relevant hashtags for Instagram and keywords for YouTube, Pinterest and Google, without stuffing.
The Copywriter studies the samples you upload, your brand description and the edits you make to its drafts. If you keep shortening captions, it writes shorter ones. If you always replace "customers" with "guests," it learns that too. Over the first few weeks, drafts need fewer changes. Your banned-words list and the Quality lead's checks act as a safety net, so phrases you never want to use stay out of your posts.
Who It Is For
Owners who know their business but struggle to write, marketing teams publishing across many platforms, and agencies writing in several brand voices every day. It is also valuable for brands reaching customers in more than one language, since the Copywriter can produce English, Hindi and Telugu versions of the same message with the right tone for each audience.
Write less, post more, sound like you
Start the free trial, add your brand kit and ask Zoe for your first captions.
The Copywriter learns from your samples and brand rules, and the Quality lead checks tone before you see it.
Can it write in my local language?
Yes. It supports major Indian languages and Hinglish.
Can I edit the captions?
Always. Edit directly or ask for a new version.
Does it write ad copy?
Yes, for Meta, Google, LinkedIn and X ads. Zoe can also plan and check the ads themselves: see Ads.
Does it make up facts?
No. It writes from the facts in your brand kit and your own words, and never invents a price, an offer, a phone number, an address or a link. Always review prices, claims and dates before approving.
