Problem
People struggle to retain and retrieve information from their personal notes, documents, and images, especially when that data is scattered across multiple tools and lacks contextual linking. Existing solutions often store data in centralized servers, expose it to third‑party training, or provide only keyword search without true understanding.
Solution
The Wheel is a private knowledge engine that lets users store notes, images, and other content and later ask natural‑language questions that draw on all saved material. The platform encrypts data end‑to‑end, ensuring only the user can decrypt and view it, and never uses the information for model training or sharing. An embeddings model converts queries into vector representations, which are matched against encrypted document vectors via semantic search. OCR extracts text from images, named‑entity recognition strips identifying details, and semantic chunking preserves context for accurate answers. Lightweight and frontier LLMs handle simple and complex reasoning respectively, all processed ephemerally to maintain privacy. Over time, the system builds connections between entries, improving relevance and recall as the user's knowledge base grows.
Target Audience
Primary users are knowledge workers, researchers, and professionals who need a secure, searchable personal knowledge base, as well as privacy‑focused individuals who want AI‑assisted recall without data exposure.
Features
- End‑to‑end encrypted storage with user‑only decryption keys
- Vector‑based semantic search across all user‑uploaded notes and extracted image text
- OCR and named‑entity recognition to index image content while stripping personal identifiers
- Semantic chunking and context linking that strengthen answer relevance as the knowledge base expands
- Hybrid LLM inference: lightweight models for quick queries, larger models for deep reasoning
- Ephemeral processing pipeline that never retains query data after response generation
- Export and delete tools giving users full control over their data at any time
