Board utility · ship faster

Mirror Copy Booster

Copy values from one column into another on the same board — fast, obvious, and boring in the best way. No exports, no spreadsheet detours, no “why is this still manual?” energy.

Board-local only OAuth you approve Built for real workflows

What it does

Seconds, not side quests

Pick source, pick destination, run once. The UI is intentionally small so your team spends time on work — not on configuring a spaceship.

Sane defaults

Text, long text, and item name destinations keep things predictable. We’re not trying to sync the universe — just unblock the copy-paste grind inside monday.

Trust-shaped

The app runs where monday runs. Data handling depends on the scopes you grant and your account setup — we don’t sell lists, we don’t run sketchy side businesses.

Pro when you need it

Free tier for light use; Pro for groups, saved rules, and heavier teams — so you can grow without throwing the whole kitchen sink in on day one.

About the builder

Puffly — small apps, sharp focus

Hey — I’m the human behind Puffly. I build tiny productivity tools because I’ve spent too many evenings watching people fight the same repetitive tasks in perfectly good software. Mirror Copy Booster exists for the “just copy this column into that one” moment that happens on every board, every week.

My rule of thumb: one job per app, done clearly. If something needs a 40-minute onboarding video, I’ve probably scoped it wrong. I care about copy that sounds like a person, UI that doesn’t shame you for being in a hurry, and shipping fixes when real users poke holes in my brilliant ideas.

When I’m not shipping, I’m usually refactoring something I swore was “final”, or explaining to friends why monday automations are cool until they’re not. If you write in with a bug or a feature that actually saves time — you’ll get a thoughtful reply, not a ticket black hole.

Builder note: I’d rather lose a feature than ship something that makes your board feel scary. If Mirror Copy Booster ever feels “enterprise heavy”, tell me — I’ll trim it.
