MindPalace: Local AI Second Brain

Privacy-first semantic search for your browser history, powered by local AI running inside your browser.

MindPalace: Your 100% Local AI Semantic Memory Bank Have you ever tried searching your browser history for an article you read three weeks ago, but you couldn't remember the exact title or URL, so it was lost forever? MindPalace solves this by replacing standard keyword search with AI-powered Semantic Vector Search. Instead of searching for exact words, you can search for concepts, vibes, or natural language questions (e.g. "those fast future computers"), and the AI will instantly find the exact Wikipedia page you were reading about Quantum Computing. How it works: MindPalace uses an open-source neural network (Transformers.js / all-MiniLM-L6-v2) running entirely inside your browser via WebAssembly. When you click "Remember Current Page", the AI reads the article, slices it into overlapping chunks, and mathematically converts the text into high-dimensional vectors, which are saved to your browser's local IndexedDB. Features: Deep Document Chunking: We don't just read the first paragraph. MindPalace slices long articles into chunks, ensuring that even a single sentence buried at the bottom of a page is instantly searchable. Hybrid Search Engine: MindPalace uses both Semantic Cosine-Similarity and Lexical Keyword boosting. If you search for an exact word, it guarantees that exact matches float to the top, while fuzzy concepts act as an unbreakable safety net. 100% Private & Local: There are no cloud servers, no APIs, no tracking, and no subscriptions. Your data never leaves your computer, and the AI model runs entirely on your own hardware. MindPalace is completely free, open-source software built to help you never lose a thought again.
