Not a hundred features — just the eight things that hurt the most
Forgot the filename? Forgot which drive? Just describe it in plain words: "find the cherry blossom photos I took in Osaka last year".
Photos are recognized by content, recordings become searchable text, documents are read in full — you search content, not just filenames.
Duplicates identified by content, not by name. Find the duplicate videos and photos hoarding hundreds of GB, clean them safely, free up space.
PC drives, external drives, NAS (SMB) and WebDAV clouds — one entry point to search and manage everything, no more digging around.
Brighten and denoise photos, restore old photos, compress and convert videos, normalize loudness, fix subtitles — processing never touches your originals.
Not everything gets backed up — you choose what. Supports local, WebDAV and SMB targets, encrypted before it ever leaves the machine.
Full + incremental backup, one-click restore, complete recovery after a system reinstall. Even if the PC dies, your files come back.
Scanning, recognition and processing all happen on your own computer. Private files are never uploaded, never leave. That's the bottom line.
