What is Collager.ai?
Collager.ai is a photo mosaic maker and AI photo collage maker. It turns the user's own photos into a photo mosaic - one big picture (a portrait, a couple, a pet) recreated from hundreds or thousands of small photos - or into a photo collage in a shape: a heart, a birthday or anniversary number, a word, a star or a flower.
This remote MCP server lets any assistant (Claude, ChatGPT, Cursor, VS Code, Codex) make these collages right in the chat. No sign-in and no API key are needed to connect.

How the result is delivered
The preview is watermarked. The full-resolution file without the watermark is downloaded on collager.ai (one credit). Prices are never shown in the chat.
Privacy
Photos are used only to build the collage or mosaic - never published, sold or used to train AI models - and are deleted automatically within 30 days. Collager.ai arranges the user's own photos; it does not generate people or scenes with AI.
