AI poster maker: an event poster from one message
Making a poster usually means fighting a design app for an hour. This prompt has your todo.is agent design the poster from your event details, keep the text readable, and give you matching versions for print, an Instagram post and Stories.
The prompt
- Make a poster for [EVENT NAME] on [DATE AND TIME] at [VENUE]. The big headline is [HEADLINE] and it should also show [OTHER TEXT]. Style and colours: [STYLE AND COLOURS]. Use [IMAGE IDEA OR ATTACHED PHOTO] as the main image. Make it portrait in A4 proportions as a PNG, with the headline readable from across a room and every word spelled exactly as I wrote it. Then make the same design as a square 1:1 version for Instagram and a 9:16 version for Stories.
What to change
- [EVENT NAME]: E.g. "Northside Jazz Night", "Spring Bake Sale", "Grand Opening".
- [DATE AND TIME]: Written as you want it on the poster, e.g. "Fri 14 March · 19:30".
- [VENUE]: Place name and short address.
- [HEADLINE]: The 2 to 6 words people should read first.
- [OTHER TEXT]: Keep it short: price, a website or "free entry". Less text means fewer mistakes.
- [STYLE AND COLOURS]: E.g. "bold Swiss style, red and black", "soft watercolour, pastel", "neon 80s".
- [IMAGE IDEA OR ATTACHED PHOTO]: Describe a scene ("a saxophone in smoky blue light") or attach a photo and write "my attached photo".

- Before you print or post
- • Check every word and number at full size; fix mistakes by replying "the date should say 14, not 4"
- • Ask for the largest size available and view it at 100% zoom before printing
- • Print at a local print shop or on your own printer; todo.is doesn’t print or post for you
- • Leave space around the edges if the printer trims the paper
How to do it with todo.is
- Copy the prompt and fill in the event details, headline and style.
- Paste it in todo.is or send it to your agent, attaching a photo if you want it on the poster.
- Your agent delivers the poster and two social versions as PNG files to download.
- Reply with fixes in plain words, like "bigger date" or "make the background lighter".
Tips
- Attach your logo and ask your agent to keep space for it, or to put it in the corner.
- For a recurring event, ask for "the same design with a new date" each time to keep a consistent look.
- Ask for a matching Instagram caption at the end of the to-do to post with it.
- Less text means a better poster: keep the main details and put the rest in your caption.
FAQ
- Can I print the poster? Yes. Download the PNG and print it at home or at a print shop. Check it at full size first, and ask your agent for the largest size it can make.
- Can I edit the text afterwards? Ask your agent to change it and it makes a new version. For full control, ask for a version without text and add the words in a design app.
- Can I use it for a commercial event? Generally yes, but it depends on the image model’s terms. If you use photos of other people or brand logos, make sure you have the right to use them.
- Will it post the poster on Instagram for me? No. It makes the files and can write the caption; you post it yourself.
