Your clients’ data doesn’t belong in ChatGPT.
Now it doesn’t have to.

Yes, completely. Stript runs multiple AI models directly on your hardware, not through a cloud API. You can verify this yourself: disconnect from the internet after the initial model download, and Stript works exactly the same. No document content ever touches a server. The only network requests are the one-time model download, a lightweight update check on launch (plus the update download itself, only if you choose to install one), and (if you activate a license) a license check with our payment provider, as well as (only if you explicitly enable them in the settings) optional crash reports (technical error data); none of them ever contains document content.

Cloud-based tools, even those hosted in Germany, still send your document to a server to process it. With Stript, the document content never leaves your device: detection and anonymization run entirely on your own hardware, and you can verify it in your network traffic. That is the core difference, on-device instead of hosted.

Stript collects no document content, no personal data, and no usage telemetry. Optional crash reports (off by default) send only technical error data with your explicit consent, never document content and nothing that identifies you. Encrypted anonymization mappings are stored only on your local machine.

Across our German and English benchmark corpora of legal, financial and HR documents, our three-stage pipeline achieves over 90% overall detection recall (measured 97–100% on the PII-sensitivity layer, depending on the corpus). Structured data like emails, IBANs, and phone numbers is detected with 99%+ accuracy. You always review and confirm before anonymization.

Stript supports PDF, Word (DOCX), email (.eml and Outlook .msg, including attachments), scanned or image-only PDFs (read on your device via OCR), and plain text. You can upload a file or paste text directly.

Absolutely. Stript is designed for professional use in regulated industries. The Enterprise plan includes self-hosted deployment via Docker, team management, and SSO/SAML integration. Your IT department stays in full control.

Stript is built for GDPR-sensitive workflows. Document processing happens locally on your device. Your document content is not sent to Stript or to third-party AI providers by the app. Stript supports reversible pseudonymization and anonymization workflows. You remain responsible for reviewing the output and deciding whether it is anonymous enough for your use case. Website, purchase, licensing, and optional crash-report data are handled separately as described in our Privacy Policy.

Stript runs on macOS (Apple Silicon, M1 or newer), Windows 10/11 (64-bit), and Linux (64-bit x86_64, as an AppImage or .deb package). Minimum 8 GB RAM, 16 GB or more recommended. You need between 3 and 20 GB of free disk space for the local AI models depending on your hardware tier, which download once on first launch and then run fully offline. Stript adapts to your hardware: on 8 GB it runs a lighter mode with smaller models, fully functional, but detection is slower and a little less accurate; with 16 GB or more it loads larger models and runs noticeably faster and more accurately. An optional GPU (Apple-Silicon GPU or NVIDIA CUDA) speeds detection up further. Either way, everything stays local on your machine.

That depends on the document and your hardware. Larger documents and scanned PDFs take longer to analyze than short letters or emails, especially on machines with 8 GB of RAM. Stript shows its progress while it works, and you can review the first detections while the deeper analysis is still running.

Because the work doesn’t stop at the download: the detection models keep improving, the app receives regular updates, and the license and update services run continuously. A one-time price couldn’t fund that ongoing work. You can cancel anytime, and the free tier stays free.

Purchases are processed by our payment provider acting as merchant of record. You can cancel a subscription at any time from the billing portal. It then runs until the end of the paid period. Details on withdrawal and refunds are set out in our Terms of Service. Read the Terms of Service →
