 ### Embeddings & Semantic Search
 
-- [ ] Implement **Hybrid Embeddings**:
-  - [ ] Default: transformer.js
-  - [ ] Optional: pull Ollama-hosted(locally) embedding models when toggled
+- [ ] Implement **Ollama Embedding Models**:
+  - [ ] Integration with Ollama embedding models (e.g., `nomic-embed-text`, `all-minilm`)
+  - [ ] Generate embeddings for chat messages and store in IndexedDB
+  - [ ] Semantic search over chat history
+  - [ ] Semantic filtering for chat sessions
 - [ ] Enable **Local RAG** over chats, PDFs, and image text
+- [ ] **Browser Search Feature**:
+  - [ ] Contextual search within webpage content
+  - [ ] Semantic search over extracted content
+  - [ ] Search result highlighting
+  - [ ] Search history
 - [ ] Optional **Web Search Enrichment**:
   - [ ] Offline-first architecture
   - [ ] Opt-in Brave / DuckDuckGo API (user-provided key)
   - [ ] WASM fallback (e.g., tinysearch) when no key
 
+> **Note**: Hybrid embeddings with client-side transformers (`@xenova/transformers`) have been tested and show degraded model response quality compared to direct text prompts. The focus will be on Ollama-hosted embedding models instead.

 ### File Upload & Processing
 
 - [ ] Plain text-based formats: `.txt`, `.md`, `.js`, `.ts` (direct read)
