See it all. Keep the best.
Drag in a pile of photos, PDFs, or drafts. Gander lines them up side by side, scores them, and helps you cull to the keepers, fast. On your Mac. Nothing uploaded.
Three takes, side by side, scored on what changed between them. The keeper is a glance, not a re-read. Illustrative view.
The fastest way to pick the winner.
Choosing between near-identical versions is slow because you cannot hold them all in your head. Gander puts them in front of you at once and scores the differences, so the keeper is easy to spot.
- 1GatherDrag in a folder, a burst, a stack of PDF versions, or a set of drafts. Gander reads them all and lays them out together.
- 2CompareEvery item, side by side, scored on what matters: sharpness and open eyes for photos, what changed between versions for documents. Near-duplicates are grouped.
- 3KeepKeyboard-first culling, fast enough that you never reach for the mouse. Mark the keepers, and export them where they need to go.
Everything you need to choose. Nothing you don't.
One pass over any pile of almost-the-same, with the slow parts done for you and the call left to you.
Side by side
Every version in view at once, at full resolution, so the differences are visible instead of remembered.
Scored for you
Sharpness and open eyes for photos. What changed, page by page, for documents. The score informs the choice; it never makes it.
Near-duplicates grouped
A burst of forty becomes a handful of stacks, each holding its best frame, so you review groups, not frames.
Keyboard-first
Keep, cut, and move through the pile without reaching for the mouse. Fast enough to clear a shoot in one sitting.
Photos, PDFs, drafts
RAW and JPEG, PDF versions, and common document drafts. One tool for every pile, not one tool per file type.
Export your picks
Send the keepers on to your library or a folder when you're done. Gander fits a pass, then gets out of the way.
Version diff for documents
Line up versions of a contract or a deck and see exactly what moved, so you keep the right one with confidence.
On-device, private
No account, no cloud, no upload. The files you're choosing between are often the ones you most need to keep private.
Buy it once
One price, no subscription. No monthly tax for a tool you reach for a few times a month.
One tool for every pile of almost-the-same.
Anywhere you have many versions and need the best one, Gander is faster than your eye alone.
Your files never leave your drive.
Gander reads, scores, and compares everything on your Mac. It does not upload your photos, pages, or drafts. There is no account, and no cloud to opt out of.
The work you are choosing between is often the work you most need to keep private: client photos, unsigned contracts, drafts no one else should see. They stay where they are.
Culling is the slow part. Gander is the fast part.
The honest answers.
Does Gander upload my photos or documents?
No. Everything is read and compared on your Mac. No file is uploaded, and there is no account to create.
Does it decide for me?
No. Gander scores and groups to make the choice fast, but the keep and cut calls are yours. The scores inform you; they do not overrule you.
What file types does it read?
Photos including RAW, PDFs, and common document drafts. If there is a format you live in, send it to us and we will look at supporting it.
Will it work with Lightroom?
Gander is built to fit a photographer's pass: cull fast, then send your picks on to your library. Tell us the exact handoff you need and we will make sure it fits.
