Show HN: Sift – Score your feed locally with EmbeddingGemma

Sift through the noise. Score your feed with EmbeddingGemma, right in the browser.

Sift is a Chrome MV3 extension that runs fully client-side using WebGPU + Transformers.js. It scores posts on Hacker News, Reddit, and X and dims low-relevance items so the good stuff stands out.

Users can label items (/) to collect training data, export it as CSV, and fine-tune the model using the included Python pipeline.
