Photo Mosaic & AI Collage Maker - Collager.ai
A photo mosaic maker and AI photo collage maker for Claude, ChatGPT and any MCP-capable agent. Turn your own photos into:
- a photo mosaic - one picture (a portrait, a couple, a pet) recreated from hundreds or thousands of your small photos. Zoom in and every tile is a real photo;
- a photo collage in seconds - a heart, a number (birthday, anniversary, year), a word, "I love you", a star or a flower made of photos.
