Hey Product Hunt, A month ago, I launched Dup 1.0 here because my Mac was drowning in duplicate photos and videos, and every existing tool only compared filenames. So I built one that actually looks at the pixels — perceptual hashing, entirely on-device — and it finds copies the big-name apps literally cannot see. Since then, the #1 request from users hasn't been "find more duplicates." It's been: **"Can I just delete every photo of [this person]?"** Breakups. Family falling-outs. Ex-coworkers. Old flatmates. The messy human reasons people want a clean photo library. That request shaped all of v2.0. ## What's new in 2.0 - Remove Someone — On-device face detection. Point at one photo of a person, Dup finds every photo and video they appear in, and the whole set is deleted in one click. Nothing ever leaves your Mac. No cloud, no account, no "we use your data to improve our AI." - Video matching — 4K original vs 720p compressed copy, different codec, different resolution, same footage? Now it matches. This was the hardest part of the rebuild. - 7 languages — English, Japanese, German, French, Korean, Simplified Chinese, Thai. ~1,500 strings, reviewed by natives (machine translation gets roasted in reviews). - The redesign — New unified design system, glass UI, a dark mode that doesn't look phoned in, and animations that make the whole app feel different. - Smart pre-selection — For free users especially: Dup picks which copy to keep (highest resolution, newest, best format) so you don't have to triage. - Stricter privacy posture — File paths are never tracked, analytics has PII filters, and all ML is on-device. The threat model assumes we are the adversary. ## Pricing - **Free** — full scanning + up to 250 MB of actual cleanup, so you can see what it finds before paying - **Pro Annual** — $24.99/yr, 7-day free trial - **Lifetime** — $39.99 one-time Available direct from https://dup.devpon.com or on the Mac App Store https://apps.apple.com/us/app/du.... macOS 13+. Under the hood, it's Tauri 2 + Rust, using `img_hash` for photos and `vid_dup_finder_lib` for video (with some invasive patches). Both libraries are really good and deserve more love than they get. **I'll be in the comments all day.** The most useful feedback you can give me is something Dup *misses* — a duplicate case it doesn't catch, a face it confuses, a UX thing that feels off. I want the roasts. — Notsu
