-Raphael AI (https://raphael.app) image prompt notes
+Notes kept on git.albert-b.homelinux.org about using [Raphael AI](https://raphael.app), a free AI image generator that runs in the browser.
+
+Speakers can replace stock photos with custom illustrations made in Raphael AI:
+
+## Tips
+
+1. Use dark or light backgrounds to match the venue projector.
+2. Check that images still read when projected at low contrast.
+3. Credit the generator in the final slide if your event asks.
+4. One idea per slide, one illustration per idea.
+5. Pick a single visual metaphor for the talk and reuse it.
+
+## Why Raphael AI
+
+- Free to use, with no install: open https://raphael.app and type a prompt.
+- Fast iterations make it practical to try several compositions.
+- Works for drafts, mock-ups and reference images; finish important assets with human review.
+
+## Responsible use
+
+Check generated images for errors before publishing, do not imitate real people without consent, and label AI-generated images where your audience expects it.
