AI that writes for you - in any text field
Postly’s AI Assistant is a standalone, inline toolbar that lives inside your text boxes. Generate captions, threads, first comments, and product posts from templates - then save, copy, post, or share straight from your Content Library.
Instagram Caption • Inline Editor
Powered by Brand KitTemplate: Instagram Caption

Tip: Use templates for X threads, LinkedIn posts, first comments, and product promos - all inline.
Brand-aware in every text field
The assistant reads your workspace’s Brand Kit so every caption, thread, and comment stays on-brand. Tone, keywords, banned words, and audience are applied automatically whenever you invoke AI.
- Tone of Voice: apply your default style without manual tweaking.
- Keywords: subtly blended in for consistent messaging and SEO.
- Banned Words: automatically excluded from suggestions.
- Audience: complexity and references tuned to who you’re speaking to.
Inline, not another screen
- • Appears when you highlight text, pause typing, or click the ✨ icon.
- • Keyboard shortcut: Cmd/Ctrl + /.
- • Classic “before vs after” preview - accept, regenerate, or cancel.
- • Fully undo-friendly: obeys your editor’s normal undo/redo.

Pick a template, fill a few inputs, and the AI Assistant generates ready-to-use content directly inside your caption, title, or description box. No separate AI screen, no copy-paste gymnastics.

FAQs
Where does the AI Assistant appear?
Anywhere you can type in Postly - captions, titles, descriptions, and first comment fields. It is an inline toolbar, not a separate screen.
What kind of content can it generate?
Captions for Instagram, X, TikTok and more, X threads, LinkedIn posts, multi-platform first comments, and e-commerce product or promo posts, all from simple templates.
How are AI credits counted?
Credits are based on AI text usage (characters). LTD plans include 20k characters per month; LTD Upgrade, Basic, and Team have unlimited usage. The AI Studio Add-on unlocks unlimited usage where applicable.
What happens when credits are exhausted?
When you hit your monthly limit, AI actions in the Assistant pause until renewal - unless you have the AI Studio Add-on, which keeps the AI Assistant fully active.
Can I reuse content later?
Yes. Save any generated content into your Content Library, then copy, post, or share it across campaigns and workspaces.
Do I have to use templates?
No. You can start from your own text and use Rewrite, Tone, Hashtags, and other actions without choosing a template.
