Reddit user ColdPudding5326 released a free, no-signup web tool for captioning LoRA training datasets. Drop in images, it calls your own API key (Gemini, Vertex, Kie, WaveSpeed or Grok) to generate captions, auto-renames files, verifies every image has its .txt, and exports a training-ready zip. Captions run through cloud APIs (images go to the provider; keys stay in your browser), but cost is tiny — roughly 50 images on a flash model costs a few cents.
