Pick Gemini 2 if
- ·Similar / fuzzy matching — Gemini finds visually similar photos (different sizes, angles, edits) and similar files. Diskaroo finds exact byte-identical copies only and will not catch near-duplicates.
- ·Guided one-click cleanup — Gemini's Smart Selection auto-picks what to remove. Diskaroo is deliberate manual review through a collector tray, by design.
- ·Deep Mac photo/music-library awareness — Gemini is tuned for Apple Photos and music libraries in a way Diskaroo is not.
- ·Large, established, heavily reviewed Mac app with a big existing user base.
- ·If your problem is photo libraries full of near-identical shots, Gemini 2 is the better tool and Diskaroo is the wrong one.
Pick Diskaroo if
- +Runs on Mac and Windows — Gemini 2 is Mac-only; one Diskaroo $19.99 lifetime license covers both desktops.
- +Dedupe and a disk-usage treemap in one app — Gemini is a standalone duplicate finder with no space visualization, so you'd still need a separate tool to see where space went.
- +Exact, byte-identical detection (Pro) via a three-pass match — built for re-downloaded files, copied folders, and screenshot dupes where a match must be literally identical.
- +Review-before-trash collector tray — you confirm the whole batch before anything is deleted, instead of trusting an auto-selection.
- +One purchase, both desktops, no per-Mac licensing question.

Bottom line
If your problem is photo libraries full of near-identical shots, Gemini 2 is the better tool — its similar-image matching and Smart Selection are genuinely good and Diskaroo does not do fuzzy matching at all. We find exact, byte-identical duplicates only. Where Diskaroo wins is narrower but real: you own a Mac and a Windows PC, you want to see where space actually went and clear exact duplicate copies, and you'd rather pay $19.99 once for both machines than buy a Mac-only dedupe tool plus a separate visualizer. That's the buyer we're for. Anyone who needs similar-photo cleanup should buy Gemini.
FAQ
Does Diskaroo find similar photos like Gemini 2?+
No. Diskaroo finds exact, byte-identical duplicates only — it will not match resized, re-encoded, or visually similar photos. For similar-photo cleanup, Gemini 2 is the better tool.
Is Gemini 2 available on Windows?+
No, Gemini 2 is Mac-only. Diskaroo runs on Mac and Windows, and one $19.99 lifetime purchase activates Pro on both desktop apps from the same account.
Does Diskaroo show disk usage like a treemap?+
Yes. Diskaroo's core is a disk-usage treemap with drill-in, list view, and filters — free. Gemini 2 is dedupe-only with no space visualization, so you'd need a second tool for that.
Does Diskaroo have auto-selection like Gemini's Smart Selection?+
No, and that's deliberate. Diskaroo uses a review-before-trash collector tray so you confirm the whole batch yourself before anything is deleted, rather than trusting an automatic pick.
