Thinkfree
Document SDKs for Apps and AI Agents
Thinkfree provides Office document SDKs for developers who need to create, edit, process, manage, and audit DOCX, XLSX, and PPTX files inside their own applications and AI agents. The Document Editor SDK handles word processing, spreadsheets, and presentations, while the Document Management SDK provides document search, retrieval, versioning, locking, and save-and-release workflows through REST APIs. The Document Governance SDK covers document governance, and Nextcloud is listed as an integration.
The platform supports AI document generation and offers a browser-based live demo with no sign-up required. Documentation includes a quickstart, playground, and API references for Word, spreadsheet, and presentation editing. Self-hosted deployment is supported through Docker-based setup on the customer's own servers, with a production checklist available.
Thinkfree is aimed at developers and organizations embedding document editing, automation, management, and governance into their products. Both SDKs are licensed by usage: the Editor SDK by maximum concurrent connections (MCC) and the Management SDK by managed account count (MAC). Free licenses cover up to 20 MCC or 20 MAC, with a 30-day trial, a renewable annual developer license for non-commercial use, and a 180-day free commercial license. Production licenses are annual, include version updates and technical support, and are priced by usage tier.
