Getting started
How do I install Kasah?
Kasah has two parts: a Chrome extension and a macOS desktop app. Install the extension from the Chrome Web Store, then download and install Kasah Desktop from kasah.ai/download. The desktop app connects Chrome to the Kasah privacy engine and manages local restoration.
Do I need both the extension and the desktop app?
Yes. The Chrome extension intercepts your prompts in the browser. The desktop app handles secure native messaging, local vault restoration, and the privacy-engine connection. Without the desktop app, the extension will show “Setup required.”
What are the system requirements?
Kasah requires macOS 12 or later on Apple Silicon (M1, M2, M3, or M4). The Chrome extension works with any recent version of Google Chrome.
How do I know Kasah is working?
When Kasah is active, you’ll see a small Kasah badge in the bottom-right corner of any ChatGPT page. The badge shows “Protected” and displays a count of items detected in your current prompt.
How protection works
What data does Kasah protect?
Kasah detects and protects names, email addresses, phone numbers, physical addresses, Social Security numbers, credit card numbers, financial figures, dates of birth, medical information, organization names, API keys, passwords, and many other types of sensitive data. It also redacts uploaded documents (PDF, DOCX, XLSX, PPTX).
What happens to my data?
Kasah’s privacy engine receives the original prompt to identify sensitive parts, then the desktop app replaces them with realistic fakes or safer generalizations before ChatGPT receives the request. When ChatGPT responds, Kasah restores reversible values in the response you see.
Does Kasah change the quality of AI responses?
No. ChatGPT receives a prompt that is structurally identical to what you typed — the only difference is that private values are replaced with convincing fakes or safer generalizations. You see your real data restored in the response.
What is the kill switch?
If Kasah cannot protect a prompt for any reason (daemon unresponsive, processing timeout), it blocks the prompt entirely. Your data is never sent to the AI unprotected. This is the VPN kill-switch equivalent — if protection is unavailable, traffic is blocked, not sent exposed.
Does Kasah work with file uploads?
Yes. When you upload a PDF, Word document, Excel spreadsheet, or PowerPoint presentation to ChatGPT, Kasah intercepts the file, parses it locally, asks the privacy engine what must be protected, rebuilds a protected version, and sends only that protected file to ChatGPT.
Troubleshooting
The badge shows “Setup required”
This means the Chrome extension cannot connect to the Kasah desktop app. Make sure Kasah Desktop is installed (download from kasah.ai/download). If you’ve already installed it, try restarting Chrome. The desktop app runs in the background — you don’t need to open it manually.
The badge shows “Starting...” for a long time
Kasah is connecting to the privacy engine. If this persists beyond 30 seconds, try reloading the ChatGPT page. If the problem continues, reinstall Kasah Desktop or contact support.
The badge shows “Paused”
You’ve disabled protection. Click the badge to open the panel, then toggle protection back on. The page will reload to reactivate prompt interception.
My prompt was blocked with “Protection is loading”
Kasah’s kill switch activated because protection was not ready in time. Wait a few seconds and try again. The badge will turn green when protection is available.
File upload failed with “File could not be processed”
This can happen if the file is encrypted, corrupted, too large for the private pilot, or in an unsupported format. Kasah supports PDF, DOCX, XLSX, and PPTX files up to 10 MB during pilot testing. Encrypted or password-protected files cannot be parsed and will be blocked to protect your data.
ChatGPT is slower than usual
Kasah protects the prompt before ChatGPT receives it, so some prompts can take a few extra seconds. If you experience persistent slowness, try reloading the ChatGPT page.
I see fake names in ChatGPT’s response
This means the stream restoration didn’t catch a fake value in real time. Kasah has a second safety net (DOM-level restoration) that scans the page and replaces any remaining fakes. If you still see a fake value, try scrolling past it and back — the DOM scanner runs on every page mutation. This is a known edge case when the AI splits a name across streaming tokens.
Kasah isn’t detecting some sensitive data
Kasah uses an AI privacy engine to decide what must be changed before ChatGPT sees the prompt. If you find data that should be protected but isn’t, please report it to info@kasah.ai so we can improve the system.
Account & billing
How much does Kasah cost?
Kasah is currently in private pilot. Pilot access is manually approved while production billing is being finalized. Public pricing will be shown before general availability.
How do I get pilot access?
Create or sign in to your Kasah account, then contact info@kasah.ai for pilot approval. Once your account is provisioned, return to kasah.ai/account and sync the Chrome extension.
How do I leave the pilot?
Email info@kasah.ai and we will remove pilot access for your account. You can also uninstall the Chrome extension and desktop app at any time.
Is my payment information stored by Kasah?
No payment information is required for the private pilot. When paid billing launches, payment processing will be handled by Stripe and Kasah will not store credit card numbers.
Privacy & security
Does Kasah collect my data?
Kasah does not sell your data, train on your prompts, or run prompt/content analytics. During private pilot, Kasah records privacy-safe operational telemetry such as setup status, error class, latency, and protected item counts. The configured privacy engine processes prompts only to decide what must be changed and create the protected version sent to ChatGPT.
Where does my data go?
The privacy engine receives the original prompt so it can produce protection operations. The AI provider receives only the protected prompt with private values replaced or generalized. Reversible restoration mappings stay local so the response can display naturally for you.
Can Kasah employees see my prompts?
No. Kasah is designed for automated privacy processing, not human review. We do not provide employee access to user prompts for support, analytics, or training.
Is Kasah open source?
The architecture is open and inspectable. The Chrome extension and Rust daemon communicate through Chrome’s native messaging protocol. You can verify the extension’s behavior by inspecting the ChatGPT request in Chrome DevTools — you’ll see that protected prompts are sent to ChatGPT, not your originals.
Compatibility
Which AI platforms does Kasah support?
Kasah currently supports ChatGPT (chatgpt.com and chat.openai.com). Support for Claude, Gemini, Perplexity, and other AI platforms is coming in future updates.
Does Kasah work on Windows or Linux?
Not yet. Kasah currently supports macOS on Apple Silicon only. Windows and Linux support is planned for a future release.
Does Kasah work with other browsers?
Kasah currently supports Google Chrome only. Firefox, Edge, and Safari support is planned.
Does Kasah work with ChatGPT Teams or Enterprise?
Kasah works with any ChatGPT plan — Free, Plus, Teams, and Enterprise. It intercepts prompts at the browser level regardless of your OpenAI subscription.
Uninstalling
How do I uninstall Kasah?
To remove the Chrome extension: right-click the Kasah icon in Chrome’s toolbar and select “Remove from Chrome.” To remove the desktop app: delete the ~/.kasah directory and the native messaging manifest at ~/Library/Application Support/Google/Chrome/NativeMessagingHosts/com.kasah.daemon.json.
Will uninstalling delete my data?
Removing ~/.kasah deletes the daemon, config, API-key file if you stored it there, and the local conversation vault used to restore historical chats. After that, Kasah can no longer restore old fake-to-original mappings.
