Everything.exe for content, not filenames — and it speaks HWP

What it does “Anything” is a local-first desktop search tool that chews through folders and builds an offline index of their contents. Type a keyword and it surfaces matches from inside the body text of HWP, HWPX, Word, Excel, PDF, images (via OCR), and email files, usually in under a second. It also keeps an in-memory filename cache for instant name-based lookups while indexing catches up.

The interesting bit The standout is obsessive support for Korean document formats, including HWP3 files from 1996–2002 and modern HWPX, rendered natively without installing Hancom Office. It even runs semantic vector search and optional RAG-style Q&A entirely on-device using local ONNX models, falling back to Gemini only if you explicitly add an API key.

Key highlights

• Indexes thousands of documents locally using SQLite FTS5 and a vector DB; with AI features disabled, the app generates zero network traffic.
• Renders native previews of .hwp, .hwpx, and .pdf without external viewers, including original layout view and side-by-side document diff.
• Supports proximity search with morphological awareness (~N token distance) and boolean operators directly in the search bar.
• Optional AI summarization works offline via TextRank; online Gemini integration is strictly opt-in.
• Real-time file system monitoring automatically updates the index on adds, edits, and deletes.

Caveats

• macOS support is Apple Silicon only; Intel Macs are not supported.
• First launch requires an internet connection to download a ~420 MB ONNX search model, so “offline-first” assumes you were online once.
• No code signing yet, meaning Windows SmartScreen and macOS Gatekeeper will complain during installation.

Verdict Grab it if you manage large archives of Korean-language documents—especially HWP—on Windows or Apple Silicon Macs. Skip it if you need Linux support or a centrally managed, enterprise-signed installer.
