The record

What it does: Precision File Search is a desktop application for searching, classifying, and understanding local files.
Search modes: It combines high-speed classic search, semantic search using a RAG pipeline, and natural-language questions with summarized answers.
Classification: Its trainable machine-learning model can classify scattered documents into user-tailored categories.
Local operation: The maker says the application and AI models can run entirely on the local machine, and that it works offline without cloud dependency.
Privacy: The maker says PFS never uploads files or search queries and that personal data is not sent to external servers.
Security: The maker lists path-traversal prevention, XSS sanitization, and prompt-injection hardening as security measures.
Languages: The site lists support for 18 languages, including English, Arabic, Chinese, French, German, Hindi, Japanese, and Spanish.
Intended users: The project README names researchers, students, developers, legal and business professionals, writers, and people organizing large local document collections as intended users.
Windows download: The project README directs users to download a Windows installer with an .exe extension.
AI model setup: The release page says an internet connection is needed on first run to download multilingual AI models, after which subsequent runs can be fully offline.
AI integrations: The README says PFS supports OpenAI-compatible inference URLs, including online providers such as OpenAI and Together.ai and local engines such as Ollama and LM Studio.
Hardware requirements: The README says the core platform runs on most modern consumer hardware with at least 8 GB of RAM; local LLM use is listed as needing a dedicated GPU, with at least 4 GB VRAM for smaller models.
License: The project README states that PFS is licensed under the Mozilla Public License 2.0 (MPL-2.0).
Business services: The README offers organizations custom feature development, enterprise integrations, priority support and maintenance, on-premise deployment consulting, and AI/RAG consulting.
