What is CAPI AI and how do you create social media designs with AI?
Updated
Quick answer
CAPI AI is the LUME Hub tool that creates social media designs and carousels with artificial intelligence. You pick a format, describe the design, attach a logo or photo and click Gerar arte (generate design). The finished design includes your text and stays in the gallery to download or schedule on Instagram. Each generation uses Capi Coins.
CAPI AI is LUME Hub's design tool. Capi, the Hub's AI, draws the whole piece for you: background, elements, your logo or photo and the text written in, ready to download or publish. This guide covers what it does, the formats, the screens and how to get started.
Who is CAPI AI for?
Anyone who needs social media designs often and doesn't want to open a design editor for every post: business owners, social media managers and agencies. It lives in the Content app under CAPI AI, from the Growth plan up.
What does CAPI AI do?
- Single design: a feed post, story, YouTube thumbnail, cover or banner from a description.
- Carousel: 2 to 10 pages in a matching style, through a three-step wizard, with AI-written page text if you want it.
- From script to design: pick a script from the Execution kit and the post's text fills the description.
- Straight to Instagram: Instagram designs can be scheduled or published from the gallery.
What formats does CAPI AI create?
| Format | Size | Use |
|---|---|---|
| Carrossel (carousel) | 1024 × 1536 px | Several pages, 2 to 10 |
| Feed Retrato (portrait) | 1024 × 1536 px | Vertical, fills more of the screen |
| Feed Quadrado (square) | 1024 × 1024 px | Classic 1:1 |
| Story | 1024 × 1536 px | Full screen, also for Reels covers |
| Thumbnail | 1536 × 1024 px | Horizontal YouTube video cover |
| Capa (cover) | 1536 × 1024 px | Horizontal, for any use |
| Banner Vertical | 1024 × 1536 px | Tall and narrow, for ads |
What screens does CAPI AI have?
The screen has two tabs:
- Criar arte (create design): starts with a format picker grouped into Instagram, YouTube and Outros (other). After you choose, you get the Roteiro do Kit de Execução block (when you have posts), Descreva a arte (describe the design), Imagens (images) and the generate button.
- Galeria (gallery): your designs, to download, download a carousel as a .zip, schedule on Instagram or delete.
At the top, the Capi Coins chip shows your balance. Click it to open the wallet, buy coins and see your history.
How to get started
- Open Content → CAPI AI and pick a format.
- Describe the design in detail and put the text that must appear in quotation marks.
- Attach your logo or a photo if they should be in the design.
- Click Gerar arte (generate design) and wait while Capi draws.
- Download it, generate again or schedule it from the gallery.

What are CAPI AI's limits?
- Up to 3 images that appear in the design (logo and photos) and up to 2 style references, each up to 5 MB, as JPG, PNG or WEBP.
- Carousels from 2 to 10 pages; each page takes about a minute to generate.
- A daily generation cap per account, which prevents unusual usage.
- No editing inside the image: to change it, adjust the description and generate again.
How do Capi Coins work?
Capi Coins pay for each generation. Your plan includes a monthly allowance, and you can buy packs when you need more. Plan coins expire at the end of the month; purchased coins don't. If a generation fails, the coins come back automatically, shown as a refund line in your history.
CAPI AI works with the rest of the Content app: the script comes from the Execution kit and a scheduled design marks the post as published. See the Content section.
Frequently asked questions
Which plan includes CAPI AI?
CAPI AI starts on the Growth plan and is also in Complete and in the free trial. Without it, the menu item shows a lock with a note that it is available on the Growth plan.
How much does each design cost?
Each design costs 1 Capi Coin. A carousel costs half its pages, rounded up, and regenerating a carousel page is free.
Does the AI write the text on the design?
Yes. Anything you put in quotation marks in the description is written on the design exactly as typed, accents included.
Where are the designs I created?
In the Galeria (gallery) tab, which shows your most recent designs. Carousels are grouped in a single card with the page count.
