4 points · Open discussionI have proof-of-concepted[1] building an entirely static website offering client-side semantic search using transformers.js[2] and Semantra*[3] with MiniLM-L12[4]. It's usable on fast connections and decent CPUs but is not delightfully fast and can't handle huge document loads. Still could be useful for some embedded documents! I hope to incorporate an auto-builder for these experiences in the next big release of Semantra.

In Serverless Semantic Search, Free tier onlyThat's a big part of the reason I built the open source tool Semantra[1]. I only really trust the semantic search part of this problem as it is constrained by context, so I tried to make the user experience good on top of simpler semantic search without any chatbot capabilities.

2 points · Open discussionHi everyone, I built Semantra over the past four weeks to showcase the power of semantic search and share the experience. I strived to make a general purpose tool so that others could easily spin up their own semantic search engines over their own content.
Semantra is a Python CLI that analyzes specified documents (text/pdf files), embeds them in chunks of text, and launches a local web server to interactively query them by semantic meaning. It is highly configurable and offers different embedding models, from Hugging Face transformers model (e.g. ones from SentenceTransformers) to OpenAI's embedding model (text-ada-embeddings-002).
The web app allows iteratively refining queries via tagging and adding/subtracting additional queries, allowing for very expressive and refined search experiences. It also presents "explanations" for search r

esults by highlighting sub-regions within the results that most closely match the query.
Take it for a spin! `pipx install semantra`
