Chakloon Sign is an online service for signing PDF documents that allows users to send documents to multiple recipients or sign them personally. The platform utilizes simple electronic signatures (SES) in accordance with the eIDAS regulation. It is part of the Chakloon package and is built upon the open-source DocuSeal engine. The service supports four languages, including English, Ukrainian, Russian, and German, with the interface language determined by the user's Passport profile.
Features and functionality
The service provides tools for managing documents through folders and a dedicated interface for signers, where they can choose to sign or refuse a document. Users can access document templates and a specific section for signing received files. To ensure transparency, the platform maintains an event history for every document, tracking stages such as upload, sending, opening, signing, refusal, completion, or cancellation. This is supplemented by an audit log and a signature certificate embedded within the PDF. Additionally, the service offers an API for developers as part of the broader Chakloon platform.
Organisation
Chakloon Sign operates as a component of the Chakloon ecosystem. It integrates with the Passport system for user authentication and utilizes a shared notification system for alerts. The service became available at its primary address in October 2026. While the underlying engine is open-source, the platform incorporates specific logic and custom interfaces developed for the service. The platform's availability and core functionalities were established during its initial launch period in October 2026.
