Features · Desktop app

Big transfers finish.
Even when you walk away.

KitSlate Desktop is the same Media Center in a small app for Mac and Windows, signed in as you. Drop a card and it sends in parts, many at once, and keeps going through sleep, a closed window and a restart. Big deliveries arrive the same way, into one folder.

01 · WHY AN APP — what a browser does to a big transfer

A browser is built to be closed. A card dump is not.

Browsers are excellent at pages and careless with a 200 GB job. Each of these has stopped a real transfer. The app is the same Media Center without the parts of a browser that give up. Everything still works in the browser, and the people you send to never need the app; it is for the jobs you cannot babysit.

The tab closes, the laptop sleepsIn a browser the upload stops where it was. In the app it keeps going: closing the window hides it, and the Mac stays awake while it sends.
“Reload site?”A browser can ask to reload in the middle of a send, and a 73 GB upload has stopped behind that box. Nothing in the app reloads while something is sending.
“Can’t open this folder”Chrome refuses to save into Desktop and some other folders, and Safari and Firefox save files one at a time into their downloads list. The app saves every file into one folder you choose.
A tab put to sleepA browser quiets tabs it thinks are idle. The app is its own process, with its own connections and the percentage in the menu bar.
02 · SEND — the same page, signed in as you

The same send page. Nothing to learn.

The app shows kitslate.app in a window of its own. Sign in once, through your own browser, and it stays signed in. Drop a camera card, a folder or a file, and the send page is the one you already know: who gets it, the note, how long the link lasts, a password, who may open it. Their link opens right away, so each file plays on their page the moment it is up.

One place for the settingsRecipients, link days, password and the Media Center defaults are set online. The app reads them.
Drop a cardA camera card, a folder tree or a single file. Folders arrive as they left the camera.
The link exists at onceAs online: the link works the moment the upload starts, and the email goes out when the last file is up.
Your recipients need nothingThey open the link in a browser, as always.
03 · KEEPS GOING — measured on our own line

Walk away. It finishes.

Close the window and it carries on from the menu bar on a Mac or the tray on Windows. Shut the lid and it picks up when the laptop wakes. Quit it, or restart the computer, and it goes on from the last part that arrived. We tested exactly that: a 1 GB upload force-quit at 33% carried on by itself when the app reopened, and one with the window closed at 22% finished hidden.

Through sleepThe upload pauses with the laptop and resumes with it. Nothing already sent is sent twice.
Through a restartThe app remembers which parts of which file have arrived, and goes on from there.
Through a dropped connectionEach part is sent again until it arrives. A network fault is a wait, never a failure.
Every part checkedEach part’s fingerprint is compared with what storage received. A file is done only when it matches.
KitSlate Desktop · Send · uploading
KitSlate Desktop uploading eight clips: 45 percent, about 6 seconds left, 10 of 12 connections sending, straight to storage, the link kitslate.app/t/gd9zkgu6 with Copy link and Open, Emailed Sam Okafor, and each clip with its own progress bar; under the progress, You can close this window. It carries on from the menu bar, through sleep, and after a restart.
Mid-upload: the percentage, the line’s speed, the parts and connections, each file’s progress, and the link already sent.
04 · RECEIVE — one folder, no account

Big deliveries arrive in one folder, and finish.

On a big transfer the download page offers Open in KitSlate. The page opens in the app, signed out, exactly as in a browser, and Download everything saves every file into one folder, in the sender’s own folders, over several connections at once. If the connection drops or the computer restarts, it carries on from the pieces already saved: in our test a 1 GB download killed at 39% picked up from there and finished.

No account, everReceiving needs no sign-in, in the browser or in the app.
One folder, all of itEvery file of the transfer, in the sender’s own folders, inside your downloads folder.
Carries on from the saved piecesA dropped line, a quit or a restart resumes the download, never from zero.
Your folderChosen once in the app’s Settings. Every transfer saves into its own folder inside it.

06 · LIGHT — a tenth the size, always current

No browser inside. It uses yours.

The app does not carry a browser of its own. It uses the one built into your Mac or PC and loads the site, so the installer is small and the pages are always the current ones: when kitslate.app changes, the app has changed. The native part, the part that reads files, sends and saves them and sits in the menu bar, updates itself.

Mac and WindowsOne Mac download for Apple silicon and Intel, and one for 64-bit Windows. The same app on both.
SignedIt opens on a Mac with no warning: signed and notarized by Apple.
Free to installYour plan’s transfer sizes and link days apply exactly as they do online.
Same speed, same routeThe browser already sends many parts at once straight to storage, and your connection is the limit. The app sends by the same route; what it adds is that the transfer finishes when you are not there.
07 · ONLINE OR THE APP — the same account, the same plan

What you get online, and what the app adds.

Everything in the Media Center works in a browser, on any computer, and the people you send to only ever need a browser. The app is the same Media Center with the parts a browser cannot do: the jobs you walk away from, and the work on files that are still on your computer.

QUESTIONS — the ones people ask first

Before you try it.

Is it faster than the browser?

On most lines, no. The browser already sends many parts at once straight to storage, and your connection is the limit. The app sends by the same route at the same speed. What it adds is that the upload carries on when the window is closed, the laptop sleeps or the computer restarts.

Do I need it?

No. Everything on this page works in the browser except carrying on through sleep and a restart. The app is for long uploads you do not want to babysit.

Does it change my plan?

No. It is free to install, and your plan’s transfer sizes, link days and storage apply exactly as online.

Where do the settings live?

Online, in the Media Center. The app reads them and has none of its own, so a change made online is already made in the app.

Do the people I send to need it?

No. They open the link in a browser and play, comment and download as always.

How does it update?

The pages are the live site, so most changes reach the app the moment they reach kitslate.app. The native part checks for a new version when the app opens and installs it on the next launch.

How do I get the best speed out of it?

The app has no speed settings; it finds the pace of your line by itself. What moves the number is your upload rate, a cable instead of Wi-Fi, and the drive it reads from. The manual lays it out, including what happens when the lid closes.

Which computers?

Macs with Apple silicon or Intel, and 64-bit Windows. There is no Linux app.

Do I need to know whether my Mac is Intel or Apple silicon?

No. One Mac download carries both, and your Mac opens the half that matches its chip. If you are curious: Apple menu → About This Mac says Chip for Apple silicon and Processor for Intel.

Drop the card. Close the laptop. It finishes.
