In-Depth Review: What is LocalChat?
LocalChat is a private AI assistant that runs entirely on your Mac. It reads full documents (PDFs, spreadsheets, notes) and answers questions without any data leaving your device. Ideal for professionals who handle sensitive information—lawyers, doctors, accountants, therapists. No cloud accounts, no subscriptions, always offline. Supports 300+ open-source models. One-time license.
Core Features
Whole file reading
Hand it a 200-page deposition, a full patient chart, or a contract. LocalChat reads the entire document on your Mac without copy-pasting.
No account or login
No sign-up required. Your prompts, files, and answers stay on your laptop; no usage tracking or cloud accounts.
Project workspace per matter
Each project keeps its own files, conversations, and embedded memory. Toggle 'answer only from this project's files' to stay case-specific.
Obsidian vault integration
Point LocalChat at an Obsidian vault to scan notes, follow links, and create searchable memory for the assistant.
Offline availability
Once models are downloaded, no internet is required. Works on planes, in basements, or on patchy Wi-Fi.
Curated model library
25+ on-device models (reasoning, vision, OCR, image gen, embeddings) tested on Apple Silicon. Swap mid-thread; conversation persists.
