The local search that actually understands Chinese — and understands you.
Your files never leave your computer. Even when you can’t recall the exact words, fanSearch still finds them — and takes you straight to the exact page.
100% Local & Private
Contracts, medical records, drafts, journals — nothing is ever uploaded. All indexing and searching happen entirely on your machine. No cloud, no account, no network required.
Find It Even by Meaning
Remember the idea but not the exact phrasing? Local AI semantic search finds the passage you mean — something keyword-only tools simply cannot do. Combined with precise keyword matching for the best of both.
Genuinely Great with Chinese
Most search tools handle Chinese poorly. fanSearch is built around proper Chinese word segmentation, so searching 时间同步 reliably finds 系统时间同步 — the way you’d expect.
Fast — But Far More Than Fast
Speed is the floor, not the ceiling. Here’s what you actually get.
Why fanSearch?
You don’t have to remember the exact words
Traditional full-text search fails the moment your memory is fuzzy. fanSearch pairs precise keyword matching with local semantic search, so “that thing I read about somewhere” becomes findable — privately, on your own machine.
Your files stay yours
Cloud search tools ask you to trust them with sensitive documents. fanSearch never sends anything anywhere. For lawyers, doctors, researchers, and writers, that’s not a bonus — it’s the reason it’s usable at all.
Lightning-fast, even on huge files
Many tools freeze the instant you open a large PDF or a long Markdown file. fanSearch’s optimized indexing engine keeps highlighting and navigation snappy even when a term appears thousands of times in one document.
Clean, focused, no hassle
- Deep text-layer indexing for accuracy and speed — no OCR guesswork.
- Native Windows 11 experience with smooth, integrated interaction.
- Lag-free preview that stays responsive as you rapidly switch files.

Developer’s note: I built fanSearch to solve my own daily frustration — “can’t find it, can’t open it, previews lag.” If you’re tired of slow, forgetful search, this was made for you.
