What this is, in one minute

Claude is the AI made by Anthropic. Its Design feature makes a real designed page from a sentence: a big headline, colors, shapes and your details, on a canvas next to the chat. You can click any text on it and change it, ask Claude to move things around, and download it as a PDF to print or send.

It's free. Anthropic's help page says Claude Design is on every plan, including Free, and we used a free account on 10/22, on a computer. Everything in this guide worked.

No design app, no templates, no boxes that won't line up. You say what the poster is for and what it must say.

Which way to use

Claude Design is for a page with words on it: a poster, a flyer, a sign or an invitation. Other guides cover the jobs around it.

Use Claude Design when

  • You need a poster or a flyer for an event, a sale or a notice, and you know what it should say.
  • You want your words on it exactly as you wrote them, big and easy to read.
  • You'll print it, hang it, or send it as a PDF or a picture.

Use something else when

  • Use Canva: You want to start from a ready template, or put your own photos on it.

    Read the guide

  • Create images with AI: You need a picture or a drawing, not a page with text.

Claude puts on the poster what you give it. It didn't make up an address for us when we didn't write one. Put every detail in your request: the day, the time, the place, a phone number.

Your first poster, step by step

Our example: the Pine Street Library is holding a book swap on a Sunday, and it needs a poster for the door.

  1. Step 1: Open Claude and click Artifacts

    Go to claude.ai and sign in. A free account is enough. In the menu on the left, click "Artifacts".

    Claude's menu on the left: New, Projects, Artifacts (marked), Code and Customize.

  2. Step 2: Click Design

    Under "Make something new" there are three cards: Docs, Slides and Design. Click "Design". A new chat opens, with a "Claude Design" label under the box.

    Make something new, with three cards: Docs, Slides and Design (marked).

  3. Step 3: Describe the poster in one sentence

    Say what it's for, every detail it must show, and how it should look. Ours: "Design a one-page poster for a book swap at the Pine Street Library: Sunday, November 15, 10 am to 1 pm. Bring a book, take a book. A big headline, three short lines of details, warm colors, no photos of people." Then press Enter.

    The request typed in the box, marked: Design a one-page poster for a book swap at the Pine Street Library. Under the box, the Claude Design label.

  4. Step 4: The poster opens next to the chat

    Claude adds a few lines of its own under your request ("Make this a Design artifact..."). That's normal. A card with the poster's name shows up in the chat ("Claude Design · Only you"), and the poster opens on the right. Ours was ready in under 4 minutes. Claude also said what it decided on its own: the library's name went in a banner at the top.

    The poster's card in the chat, marked: Pine Street Library Book Swap Poster, Claude Design, Only you. Next to it the poster: Pine Street Library at the top, a big Book Swap headline, Sunday, November 15, 10 am to 1 pm, Bring a book, take a book, and a row of colored book shapes at the bottom.

  5. Step 5: Change any text by clicking it

    Double-click a line of text on the poster. It turns into a box you can type in, with a small toolbar over it for the font, the color and bold. Type the new words. We made the swap an hour longer: "10 am - 2 pm". Then click an empty gray spot on the canvas, next to the poster. That keeps the change. When we pressed Enter instead, the old text came back after we reopened the poster.

    The poster with the time line open for typing, marked: 10 am - 2 pm.

  6. Step 6: Export it as a PDF

    Happy with it? Click "Export" at the top right, then "PDF". "PNG" makes a picture instead, to send in a message or post online. "HTML" is a web page.

    The Export panel: Sharing isn't included in your plan, but you can export a copy. HTML, PDF (marked), Document for printing and sharing, and PNG.

  7. Step 7: Click Save file

    Claude asks "Let this artifact download a file?". Click "Save file". The PDF goes to your Downloads folder. Ours was one letter-size page with every word exactly as it was on the poster, our new time too. Print it, or attach it to an email.

    The question Let this artifact download a file?, with Pine Street Library Book Swap Poster.pdf, 281.8 kB, and the buttons Cancel and Save file (marked).
