BEFORE YOUR FIRST DOCUMENT
A short setup.
A local model.
What you need
- Windows 11 or Windows 10 22H2+, x64
- 16 GB RAM recommended
- About 12 GB free disk space for setup and model
- Internet for verification and initial downloads
- Your own OpenAI API key if you enable cloud chat
Python and Node.js are included or unnecessary. Ollama and model weights are separate from the installer.
Verify your email and install.
Download the Windows installer and follow the illustrated guide. Installation is per user by default.
Set up Ollama and the Qwen model.
Install Ollama if needed. SanitizeGPT reuses a compatible local model or asks before downloading the pinned qwen3.5:4b model (about 3.32 GB).
Start with a fictional PDF.
Review every finding and the outbound preview. Scanned PDFs and OCR are outside this beta.
Is the beta free?
Yes. SanitizeGPT is free during beta, with no announced end date. No payment card or automatic billing. Future pricing will be announced separately.
Do my original documents leave my computer?
PDF extraction, Qwen detection, review, and placeholder mappings run locally. Optional cloud chat sends the sanitized context and prompt that you review. Detection can miss information: always inspect the outbound preview.
What can I open?
The Windows beta supports PDFs with an existing text layer. Scanned PDFs and OCR are not supported. Review up to five documents in a chat session.
What is included in the installer?
The installer includes the browser interface, Python processing runtime, and self-contained launcher. You do not need Python or Node.js. Ollama is installed separately; the pinned qwen3.5:4b model is downloaded only with your permission.
Can I use it offline?
After Ollama and the model are ready, local PDF review and detection can work offline. Cloud chat requires internet access and your own supported OpenAI API key. Initial downloads and email verification also require internet access.
What should I know before trying it?
This is an early Windows x64 beta. The installer is unsigned, detection needs human review, and clean-machine verification is still pending. Use synthetic or de-identified documents for your first test.
