Mo-Search in action
Why Mo-Search feels different.
Private and fast by design; honest about what we do.
Instant ranked results
Weighted relevance blends hits, density, recency, and favorites so the right file is usually first.
Scales to millions
Indexes 2M+ files across long-lived archives with a small memory footprint and background AutoIndexer.
Deep filters & viewer
Combine text, filename, path, type, and date. Preview and analyze files without leaving the results.
Search that corrects itself.
Misspell a word in Advanced Search and Mo-Search offers the fix before you notice the mistake — accept it and the ranked results follow. Every search is saved too: reopen the history dropdown to rerun one from last week without retyping it.
What's new.
Only the latest release shown here — full history and search on the Releases page.
