Every button, up close.
See a real screen from the app, taken on a user's own computer.
The conversations are blurred on purpose.
Let it run, or click through at your own pace.
Prepare to be surprised.
Your personal account and your work account side by side on the same screen, with far more than that.
With AI triage and colour tags to find the conversation that matters.
Mac, Windows and Linux, three languages, and no server of ours anywhere in between.
Do not use the browser. Two WhatsApp Web tabs eat memory, fall asleep when you switch windows and let notifications slip. SplitChat is a real application: it opens fast, stays light on every system, and does far more than any tab could.
Drag the line in the middle, that is exactly how it works in the app.

Not an auto-reply. Real service: you teach it your business in a few steps and your AI starts answering on its own, on the account you choose, inside the hours you set.
Business name, signature, hours and the first message. That is all. Within minutes the AI knows who you are, what you offer and how to talk to whoever turns up.
The bot is capped. It never starts a conversation, never blasts a list and never answers the same contact twice in a row. That exists so your number does not look like a spam robot and so you do not risk a restriction on your WhatsApp Business account.
One account at a time, chosen by you. The work account answers on its own while the personal one stays untouched, with no bot replying to your family.
Set the days and the window. Someone writing at 11pm gets the away message and knows when you are back. No pretending there is someone awake on the other side.
Real screenshots, taken on a user's machine. The conversations are blurred and the phone numbers replaced with fictional ones: these are real working accounts.
The number connected on each side, the name you give each account and the folder its files land in. Nothing gets mixed up.
Pick the provider and paste your own key. On Gemini it is free and asks for no card. What you ask goes from your computer straight to the provider.
English, Portuguese or Spanish. Dark, light or high-tech. You choose once and the app opens that way every day.
If you answer clients on a work number and your family on a personal one, you spend the day switching apps, missing messages and replying from the wrong account. SplitChat fixes that with a single window.
Each side has its own login and its own QR code, fully isolated from the other. This is not one account mirrored twice, it is two different accounts, at the same time.
One button summarises everything still unanswered in that account, grouped by urgency. Another drafts and sends a message from a plain-text request, always asking you to confirm first. Works with Gemini, ChatGPT or Claude; Gemini has a free tier that does not even ask for a card.
Mark conversations green, orange or red. The row is tinted in the list, and one click on a colour shows only the conversations carrying it.
Close one side and the remaining account takes the whole screen. In place of the closed side you can open a tabbed notepad, today's call notes, what the client asked for, what you must not forget, right next to the conversation. Bring the account back with one click.
You get all three builds from the same link: .dmg for Mac, .exe for Windows and .AppImage for Linux. Mac at the office and Windows at home? Install both, same purchase.
There is no server of ours in the middle. The app talks straight to the messaging service, the way your browser does, and collects absolutely nothing. Here is exactly how.
Switch on automatic replies for the work account and it answers people who wrote and are still waiting: a greeting for new contacts, a numbered menu, keyword replies and an away message outside working hours. If you want, the AI writes the reply following the instruction you gave it.
It never starts a conversation, never sends a broadcast, and stops the moment you take over at the keyboard. The limits ship tight, because protecting your account matters more than answering fast.
English, Portuguese or Spanish, it changes the whole app, menu bar included. And three looks: dark, light and high-tech, graphite with cyan accents. The web interface follows the theme you pick.
WhatsApp Web in two tabs eats memory, falls asleep when you switch windows and lets notifications slip. This is a native application for Mac, Windows and Linux: it opens fast, takes little room and keeps working while you do something else. And it gives you what no tab can: two real sessions, AI, tags, notes and an automatic agent.
Lending the laptop, changing phones, selling the machine? One button disconnects just that account; another wipes everything, accounts, notes, tags, photos and AI key, without going through us.
Each account saves attachments to the folder you choose, automatically. Client documents never mix with family photos.
Ctrl 1 and Ctrl 2 expand one account to full screen; the other becomes a thin strip that still shows how many messages arrived. Ctrl 0 splits again. Zoom is per account: Ctrl + and Ctrl −. On a Mac, ⌘ instead of Ctrl.
Most apps that promise to "organise your WhatsApp" ask you to connect your account to a server of theirs. This one does not, because no server of ours exists. It is worth understanding that difference before installing anything at all.
No analytics, no automatic crash reports, no online licence check, no install ping. There is no sign-up and no user account, so there is no database of ours that could ever leak.
Your notes and your AI key are written to disk encrypted, with the key held by the macOS Keychain or Windows DPAPI and bound to your user account. Copying the file to another computer gets you nothing.
If you use the AI feature, the app replaces contact names with "Contact 1", "Contact 2"… before sending, and restores the real names in the answer, locally. The provider gets the subject without learning who you talk to. On by default.
The Hide conversations button (or Ctrl L) blanks the screen instantly, and only your 4 or 6 digit PIN brings it back. It can hide by itself after a few idle minutes, and when the computer sleeps or the screen locks.
The PIN is stored nowhere, only a one-way mark of it. Hiding the screen from someone walking past is exactly what it promises, and exactly what it does.
Settings → Privacy → Erase everything disconnects the accounts and deletes notes, tags, photos, layout and the AI key from that computer. It is immediate and it does not go through us, there would be no way for it to.
Because the content of your conversations never reaches us, we are neither controller nor processor of it. All of it is written down, without legalese, in the privacy policy and the terms of use.
A privacy promise is worth nothing unless you can verify it. Every line below comes with a way to check it yourself, without taking my word for it.
shasum -a 256 path/to/file. Windows: in PowerShell, Get-FileHash path\to\file. Linux: in the terminal, sha256sum path/to/file.
I do not claim the app makes you "anonymous" or "untraceable". It changes nothing about the messaging service itself: whoever has access to your phone or your account still has it. What I guarantee is what is under my control - that I never see, store or pass on anything of yours.
The app keeps working. It does not depend on a server of mine to launch, to validate a licence, or for anything else. If I stop shipping updates, you are left with a copy that runs exactly the same, which is not what happens with a subscription service.
The app ships with the AI ready to go. What it does not ship, and no app can ship honestly, is a built-in API key. You connect your own, in about a minute.
The recommended option and the app's default. You create the key in Google AI Studio with your Google account, with no credit card, paste it into the app and that is it. It is the only one of the three that costs nothing.
Pick the provider in settings and use your developer account's key. With those two, usage is billed by them, typically fractions of a cent per query.
Careful with this one: ChatGPT Plus, Claude Pro and Gemini Advanced are chat subscriptions and do not include API access, which is a separate product. If all you have is the monthly plan, use Gemini, it is free.
From download to first use
As soon as the payment clears you get the link with all three builds. On Mac, drag it to Applications; on Windows, run the installer; on Linux, make the .AppImage executable and open it.
Open the app and connect each account from its own phone, exactly the way you already do on the web version.
Drag the divider, pick a language and theme, add a photo to each account and set where its files should land.
One purchase. No subscription, no recurring charge.
No. The app runs entirely on your computer and talks straight to the messaging service, like a browser. There is no intermediary and nothing is collected. If you use the AI feature, only the names and previews of the selected conversations go to the provider you chose, with your key, at the moment you click, and by default the names are swapped for aliases first.
Two answers. The practical one: the app has no sign-up, no user account and opens no connection to any server of ours, there is nowhere for data to go. The verifiable one: an app like this is a package anyone technical can open and read, and the only connections in the code are to the messaging service itself and, if you configure it, to the AI provider you picked yourself.
It does not have to. The app supports three providers. Google Gemini, ChatGPT and Claude, and you choose in settings. Gemini has a free tier that does not require a credit card: create the key in Google AI Studio in about a minute, paste it in, done. And the app works perfectly with no AI at all, you simply won't have the summary and drafting buttons.
On both. One purchase gives you all three builds from the same link: the Mac .dmg, the Windows 10 and 11 .exe, and a 64-bit .AppImage for Linux that runs on current distributions without installing anything into the system. Every feature is identical across the three; only the shortcut key differs, Ctrl on Windows and Linux instead of ⌘.
Settings → Accounts → Disconnect, on whichever account you want. That login disappears from that side while the other keeps working. Your messages on the phone are untouched. To wipe the whole computer, Settings → Privacy → Erase everything does it in one go.
Yes. Install it on your other machine and scan the QR codes again, each computer keeps its own sessions.
Yes, exactly as with the messenger's own web version: the phone needs to be online for conversations to sync.
You can. The app takes as many accounts as you configure and divides the width between them. Two is the default because that is what fits comfortably on a laptop screen.
You get your money back. Write within 14 days telling us what happened and the refund goes through, no argument, no justification needed.
There is no call centre, no ticket number and no automated chat. The person who answers is the person who wrote the app. I send you the steps, and if needed I jump on a call and look at your screen with you.
Best for screenshots, error messages or a refund request. Reply within one business day.
Install on all three systems, connecting accounts, the AI and the auto-reply bot. It comes with the purchase.
14-day refund. If it does not work for you, write and you get your money back, no argument and no justification needed. It is written into the terms of use, not just a line on a sales page.
One purchase, one download, and your two accounts finally fit on the same screen.
