The developer workbench
for your Mac.

Small utilities I kept rebuilding as web pages. Now they're one native window. Paste something, Bench guesses the tool. Works offline. Pay once.

02 · METHOD

Smart where it counts. Quiet everywhere else.

A small rule-based check reads your clipboard and picks a tool. It runs on your Mac. Nothing is sent anywhere.

Smart Paste

Paste a JWT. The decoder's already open.

Copy a chunk of JSON, switch to Bench, and the formatter is waiting. Copy a hex color, and the converter is open. Copy a JWT, and it's already decoded. Nothing to click.

The detection is regex and string checks. Maybe 200 lines. It's a rule‑based heuristic that runs on your Mac, with no network code compiled in. If it doesn't recognise what you pasted it just gives up quietly and lets you pick.

06 · FAQ

Questions you might ask before buying.

If yours isn't here, email [email protected]. Every message is read by a human.

Does it work offline?

Yes. Every tool runs entirely on your Mac. No tool in Bench makes network calls. The one exception will be Apple's purchase/restore flow once the app is live, which is handled by macOS itself and uses the network to talk to Apple, not to us.

How much is Bench, and what do I get?

Bench is $19, one‑time. That unlocks every tool, including Smart Detection, and includes one full year of updates. Your version keeps working forever. There's no time limit on what you bought.

What's the $9 renewal, and is it required?

It's optional. After your first year, you can pay $9 for another year of new updates. If you skip it, the version you already have keeps working with no nags and no expiry. There's no subscription and nothing auto‑charges. We have a dedicated renewal FAQ that spells out exactly how it works.

If you raise the price, does my renewal go up too?

No. Your renewal price is locked at the rate you started on. If the list price of Bench goes up later, the cost to renew your copy stays where it was. We made this an explicit commitment, not a vague intention.

What if I skip a year and want updates again later?

Come back whenever. You can renew at any time to start receiving new updates again. There's no penalty and no back‑payment for the years you skipped.

Does it sync between my Macs?

No. Bench keeps everything local on the Mac you're using. There are no accounts, no servers to sign into, and nothing is sent anywhere for you to sync against. If you want your recent inputs on another Mac, copy and paste them.

Is it a universal binary?

Yes. Bench ships as a universal binary that runs natively on Apple silicon and Intel Macs. The minimum system requirement is macOS 14.

What data does Bench collect?

None. Bench has no analytics, no telemetry, no third‑party SDKs, and no account system. Smart Paste reads your clipboard locally to pick a tool; the detection is a rule‑based heuristic that runs on your device. Whatever you type, paste, or generate stays on your Mac.

How do updates work?

Once Bench ships, updates will arrive through Apple the same way as any Mac app you install from the store. You won't need to do anything special; macOS handles the install when an update is available.

Can I get a refund?

Once the app ships, purchases and refunds will be handled by Apple. You'll be able to request a refund from Apple directly via reportaproblem.apple.com. If something in the app isn't behaving, email [email protected] first. There's a good chance it's a fixable bug.
