What are attachments?

Attachments let you add files to a prompt so the AI can reference them when building or refining your project. You can attach a screenshot of a design you want to copy, a PDF brief with requirements, a CSV with sample data, or a Word document with copy you want to use verbatim.

Attachments are available both on the homepage prompt (when creating a new project) and in the chat input on any project page (when sending a refinement).

Supported file types

  • Images — PNG, JPEG, GIF, SVG, WebP, ICO
  • Documents — PDF, DOC, DOCX
  • Text & data — TXT, CSV

Long text prompts are also automatically converted to .txt attachments when they exceed the inline size limit, so nothing gets truncated.

Limits

  • Up to 5 files per message
  • Maximum 5 MB per file
  • Maximum 20 MB total across all attachments in one message

How to attach files

  1. Click the paperclip icon next to the prompt input.
  2. Select files from your computer, or drag and drop them onto the input area.
  3. Image attachments show a thumbnail preview; documents show the file name and size.
  4. Remove an attachment with the X button on its preview before sending.

Tips for using attachments effectively

  • Reference attachments in your prompt— Say "use this layout" or "match the style in the screenshot" so the AI knows what to do with the file.
  • Crop screenshots— Smaller, focused images give better results than full-page captures.
  • Use CSV for sample data— If you want the AI to generate a UI for specific columns, attach a CSV with a few example rows.
