Show HN: Moss – AI-Powered Semantic Search Running In-Browser (No Cloud)

Hey HN,

We’ve been heads-down building MOSS - a semantic memory layer that brings AI-powered search and personalization fully on-device (No cloud | No latency | No data leaving the user’s device)

We just launched a live demo showing MOSS running entirely in-browser, performing lightning-fast semantic search over local in-browser VectorDB. This unlocks a new class of privacy-first, hybrid AI experiences that work even without a server connection.

If you’re curious about:

- how to run AI search right inside the browser

- the technical challenges behind on-device vector search

- why we believe the future is hybrid (edge + cloud)

… we’d love for you to check it out, break it down, and share your thoughts.

Let’s push on-device AI forward together!

how are you thinking this will be deployed and how will developers initially integrate this? ie is this a language-level library, or an internal service in a docker container to deploy?

one idea, is vitepress (vitepress.dev) has a local search engine, it would be cool to have moss integrated in that project, https://github.com/vuejs/vitepress

who benefits from this?

MOSS benefits any team or developer who wants to add "ask anything" semantic search and personalization without standing up extra backend services. That includes `indie devs`, `small SaaS teams`, `mobile apps`, and `privacy-conscious or regulated products` where sending data to the cloud is problematic. By bundling the entire stack - embeddings, vector DB store, and retrieval - into a lightweight on-device module, you avoid months of backend integration, reduce ongoing costs, and unlock private, instant UX even offline. Beyond search, we see this enabling per-user personalization without the privacy trade-offs of cloud-based systems.
