Preview-first local file sync manager

See every change before overwriting a single photo or file

Problem

A developer launched FileLever to solve the lack of preview in sync and backup tools. Many people shuttle photos and videos between local drives, NAS, USB, SD cards, and cloud folders, terrified of overwriting files that aren't backed up or duplicating everything. Most tools either execute blindly or overwhelm users with complexity, so hitting sync feels risky.

Solution

A local-first folder sync and backup tool built around preview-before-write. It scans source and destination, then shows adds, overwrites, deletions, and duplicates in a clear list for item-by-item confirmation. Works with local drives, external HDDs, NAS, SD cards, and locally synced cloud folders, with photo archival as a first-class use case.

Users

Everyday users with large photo/video libraries, photographers, content creators, and anyone managing multiple external drives and NAS.

MVP

Scan and compare two folders; categorize as new, modified, deleted, duplicate; confirm item-by-item or in bulk; generate a change log after execution; support local, external, and NAS-mounted paths.

Revenue

One-time purchase at $19–$39, or free basic tier plus $3–$5/month subscription for advanced photo archival.

Why now

Personal data keeps growing while cloud storage prices rise and privacy concerns grow, pushing people back to local multi-drive backups. Existing sync tools target programmers or enterprises, leaving room for a preview-first experience for normal users.
