Image Caption Recommender

Suggests the best-fitting social media caption for a photo using CLIP

1-2 weeks build

Overview

Rather than generating text, this kit retrieves it. A bank of a few thousand captions is embedded once with OpenAI's open-source CLIP model, and each uploaded photo is embedded into the same space and matched by cosine similarity. Users can filter by mood such as funny, travel or motivational and get the five closest captions.

What makes it stand up

  • 01Retrieval-based design with no text generation needed
  • 02CLIP image and text embeddings in one shared space
  • 03FAISS index for instant nearest-neighbour lookup
  • 04Mood and hashtag filters on the caption bank
  • 05Top-five suggestions with similarity scores
