Frequently Asked Questions

Can Klause replace a lawyer?
No. Klause is an informational document Review tool. It helps you understand terms, obligations, risks, missing protections, and questions worth raising, but it does not provide legal advice.
Does Klause store my document?
Klause stores Review session data. Anonymous Review sessions are deleted after 24 hours. Signed-in saved Reviews and their document context remain until the Review or account is deleted, so eligible users can use Review History and document-grounded follow-up questions. See the Privacy Policy for the full retention schedule.
Are my documents used to train AI?
Klause does not use submitted documents to train a Klause-owned foundation model. Document text is sent through OpenRouter to the configured AI provider to produce the Review, and provider handling is subject to the applicable model and provider settings.
Which file types are supported?
The Review flow supports PDF, DOCX, TXT, Markdown, and CSV, subject to current file-size and document-length limits.
How accurate is a Review?
A Review can miss context, misunderstand wording, or produce incomplete findings. Severity labels prioritize attention; they are not probabilities or guarantees of legal accuracy. Verify high-stakes decisions with a qualified legal professional.
What does Klause cost?
The Free plan includes 1 complete Review with no credit card. Pro is $9.99 per month and includes unlimited Reviews, saved Review History, follow-up questions, and PDF reports. Business is not yet available.
