Sáttmál
Sáttmál (Old Norse for agreement) is a private, AI-powered contract signing and analysis app for macOS. It is designed for individuals, families, and small teams who want to handle confidential PDF agreements without relying on cloud services or external servers. The app runs locally in the user's browser interface via a standalone macOS installer, ensuring that documents and signatures remain on the user's own computer. All data is stored using local JSON and filesystem storage, with no external database or third-party server involved, making it a highly privacy-centric alternative to widespread cloud-based e-signature platforms. Core functionality includes easy PDF upload and organization, browser-based digital signing through drawn or uploaded signatures, and complete local document management. Sáttmál also offers a unique Explain Mode, an optional AI-powered feature that can simplify complicated legal text using Ollama or OpenAI integrations. This allows users to receive plain-language explanations of contract clauses before signing, helping them make more informed decisions. Signed documents can be shared securely via email directly from the app, and end-to-end encryption is advertised to keep files and signatures safe. The application is lightweight and standalone, requiring no heavy software installation or database setup beyond the macOS installer. Its user experience is tailored to both home and small office scenarios, supporting multiple users on the same machine. By combining local storage with optional AI analysis, Sáttmál aims to give users confidence, clarity, and control over their agreement workflows. Sáttmál is developed by Social Climate Tech and is supported by donations, requiring a minimum contribution of 49 EUR for the downloadable macOS app. The product page emphasizes privacy, simplicity, and transparency, distinguishing it from mainstream cloud-based contract signing tools.
