Frequently Asked Questions

It generates posters for promotions, menus, holidays, course enrollment, public service, product launches, grand openings and hiring. Pick a purpose to start from a template, then edit the prompt: lines with a colon are printed on the poster as written, and other lines guide the design. Product photos can be added as reference images, and Write with AI rewrites the whole prompt for the selected purpose while keeping the prices, dates and phone numbers you entered.

Yes. A flyer is made the same way as a poster: pick a purpose such as Promotion, Grand opening or Hiring, then enter the headline, offer, date and contact details you want on it. Choose 3:4 portrait for a classic flyer layout, and a higher resolution such as 2K or 4K if you plan to print it. Add a QR code to link the flyer to your store, menu or sign-up page.

No. A poster can be generated from the prompt alone. Reference images are optional: add product photos, a logo or a portrait in JPG, PNG or WebP. Each one is used according to what it shows, with products and faces kept true to the original and logos reproduced unchanged. In the prompt, refer to them as Image 1, Image 2 and so on.

Yes. In the QR code section, upload your code and choose a position: bottom right, bottom left, top right or top left. The poster is generated with that corner kept clear, and your original code is then placed there on a white card, so it scans the same as the image you uploaded. Use a sharp, high-contrast image of the code. The QR code does not count toward the reference images or change the cost.

Yes. Poster generation requires a free LubanAI account. Posters are billed to purchased credits or a subscription, starting at 2 credits each, and the exact cost appears on the generate button before you submit. Credit packs and subscriptions are available on the pricing page.

Poster cost depends on the model and quality tier. Starting price is 2 credits per poster. The exact cost is displayed on the generate button before you submit, and credits are returned automatically if the run fails.

Lines in your prompt that contain a colon are printed on the poster as written. Both models offered here were selected after character-by-character text accuracy tests, and shorter lines render more reliably, so keep headlines and offers concise and check each result before printing or publishing.

Posters come in three formats: 3:4 portrait (the default), 1:1 square and 16:9 landscape. Resolution depends on the model: GPT Image 2 offers 1K and 2K with low, medium or high quality, and Nano Banana Pro offers 1K, 2K and 4K. Higher resolutions suit printing, while 1K covers most social media and online use.

Along with the main poster, you can add Instagram Stories (9:16), Instagram feed (4:5), Facebook (1.91:1), Xiaohongshu (3:4) and Pinterest (2:3). Select the sizes you need, and the whole set downloads as one zip file.

Each additional size is charged as one poster at the model and quality you selected, with the main poster used as its reference image. Sizes that share the main poster's format are cropped from it at no extra charge. Every size is checked against your text: if a size does not match, it is regenerated once automatically, and if it still does not match, the credits for that size are refunded.

Yes, for images you own or have licensed. No attribution is required on paid plans or credit packs; free-plan outputs require attribution to LubanAI. Results are kept for 30 days (7 days for free accounts). See our Terms of Service for details.

Tasks are processed in the order they are submitted. Paid tasks from subscribers and credit pack buyers are picked up first. Free tasks may wait longer during peak hours.
