# What is creative automation? Templates, data and a renderer — and the three ways to do it > Creative automation means producing many images, ads or documents from one template and your data: how it works, the three approaches, and what each suits. Published 2026-11-08 · https://shareglint.com/en/guides/what-is-creative-automation Creative automation is the production side of design: making **many versions of one design** without opening a design tool for each. A designer — or a developer — builds a template once; data fills it; software renders every version. One template, a spreadsheet of 400 products and six social sizes become 2,400 images. A launch announcement in eight languages becomes eight images from one design. Every page of a website gets its own share image the moment it is published. ## How it works Every creative automation setup, whatever the vendor, has the same four parts: 1. **A template** — the design, with some parts marked as variable: a headline, a photo, a price, a date. Everything else — layout, fonts, colours, logo — is fixed and approved once. 2. **Data** — the values for each version: rows in a spreadsheet, records in a database, a product feed, a form submission, an event in your app. 3. **A renderer** — the software that puts each set of values into the template and produces a file: PNG, JPEG, a PDF, a short MP4. 4. **Delivery** — where the files go: a social scheduler, an ad platform, an email, a web page's `og:image` tag, a download folder. The value is in the combination: designers control the look once; whoever owns the data — marketing, product, engineering — produces as many versions as needed, and they are all correct. ## A concrete example On 2026-11-08 we rendered our built-in `flash-sale` template, with one headline and discount, in all of our size presets — og 1200×630, square 1080×1080, portrait 1080×1350, story 1080×1920, pinterest 1000×1500, youtube 1280×720 — with a single API request on our development stack: ```json { "template": "flash-sale", "sizes": ["og", "square", "portrait", "story", "pinterest", "youtube"], "modifications": { "title": "48-hour flash sale", "discount": "30%", "ends": "Sunday midnight" } } ``` All six images came back in **3.4–4.0 seconds** over two runs, each laid out for its own shape rather than cropped. That is the core of creative automation: the work of resizing and re-typing disappears, and the result is consistent by construction. ## Three ways to do it ### 1. Design-editor platforms You design templates in the vendor's visual editor, much like a design tool, and fill them from spreadsheets, integrations or an API. Bannerbear, Placid, Abyssale and similar products work this way; some add approvals, ad formats and brand kits for marketing teams. **Good for:** designers who want a visual editor and marketers who run campaigns without developers. **Watch:** templates live in the vendor's format; seats and credits add up. Our comparison pages for [Bannerbear](https://shareglint.com/en/alternatives/bannerbear), [Placid](https://shareglint.com/en/alternatives/placid) and [Abyssale](https://shareglint.com/en/alternatives/abyssale) say where each is stronger than us. ### 2. HTML and CSS templates The template is a web page — HTML and CSS with placeholders — and a real browser, usually [headless Chrome](https://developer.chrome.com/docs/automation-and-testing/headless), renders it to an image or PDF. This is how we work (with a simple visual editor on top), and how teams build it themselves with Puppeteer or Playwright. **Good for:** developers, anything that is generated by code, layouts that must handle long text in many languages, and image URLs that render on request. **Watch:** someone has to write HTML and CSS; running your own browsers is real operations work ([building it yourself](https://shareglint.com/en/guides/og-image-with-puppeteer)). ### 3. Generative AI Instead of a fixed template, a model creates an image from a prompt each time. **Good for:** ideas, backgrounds, illustration, variety. **Watch:** each image is different, layout and brand are hard to hold, and text in images is unreliable — not what you want for a price, a date or a legal line. A common pattern combines the two: AI for a photo or background, automation to place it in an approved template with exact text. ## What teams automate - **Social media:** the same post in every platform size; a card for every blog post, podcast episode or quote ([social media images](https://shareglint.com/en/use-cases/social-media-images)). - **E-commerce:** product images with price and badges from the catalogue, sale banners, back-in-stock posts. - **Ads:** variants by audience, language and size from one design. - **Websites:** an [Open Graph](https://ogp.me/) image for every page, generated when the page is published. - **Documents:** certificates, tickets, badges and one-page PDFs from a list of names. - **Email:** personalized header images per recipient. ## Signs you need it - You make the **same design more than a few times a week** with different text or photos. - **Sizes multiply the work**: every post needs four or six formats. - **Mistakes cost**: a wrong price or a misspelled name in a hand-edited image. - **Content already lives in data**: a product feed, a CMS, a spreadsheet, a database. ## How to start small Pick one job you already do by hand every week — the blog post image, the weekly sale banner, the event speaker card — and automate only that: 1. Turn the current design into a template and decide which parts change. 2. Find where the data already lives and how to get it out: a CMS field, a spreadsheet column, a product feed. 3. Render ten real examples, including the longest title and the strangest name, and fix the template until all ten look right. 4. Connect delivery last — a scheduler, an email tool, the page's `og:image` tag. Measure the time saved on that one job before adding the next. Most of the effort goes into step 3: a template that handles real data, not the demo text. ## What we do, and do not do Shareglint is the second approach: HTML/CSS templates (153 built in, or your own) rendered in Chrome to PNG, JPEG, WebP, one-page PDF, or GIF/MP4 animations of up to 5 seconds, from an API, signed URLs, CSV batches, no-code HTTP recipes or an MCP server for AI assistants. We do **not** edit video, run ad campaigns or ad serving, host a digital asset library, or provide approval workflows; for those, the editor-based platforms or a dedicated ad stack are the better fit. The [one template, every size](https://shareglint.com/en/features/one-template-every-size) page shows the multi-size rendering from the example above. ## FAQ ### What is creative automation? Producing many versions of a design automatically: a designer makes a template once, data fills it — names, products, prices, dates, languages, sizes — and software renders every version. It replaces copying and editing a design by hand for each variant. ### What is the difference between creative automation and generative AI? Creative automation fills a fixed, approved design with exact data, so every version is on brand and the text is exactly what you sent. Generative AI creates a new image from a prompt each time: more variety, less control over layout, text and brand. Many teams use AI for ideas and automation for production. ### What can be automated? Anything that is the same design with different content: social posts in every size, ad variants, product and price images, Open Graph images for every page, certificates, event badges, quote cards, email headers. One-page PDFs and short animations work the same way. ### Do I need a design tool to use creative automation? It depends on the approach. Editor-based platforms let designers build templates visually; template APIs like ours take HTML and CSS (or a simple visual editor); both then fill the template from a spreadsheet, an integration or an API call.
