Announcing StackOne Documents API - a unified API and File Picker for your customers' knowledge
Integrate once to access every customer document — across cloud storage and knowledge bases — with a native picker and real-time, privacy-first architecture.
StackOne launched the Unified Documents API and File Picker, designed for AI agents, RAG pipelines, and enterprise SaaS applications requiring secure document access. The platform addresses integration challenges across multiple providers like SharePoint, OneDrive, Google Drive, Confluence, and Notion through a single unified interface.

- Lack of standardized file selection across providers

- File sharing in live chat conversations
- Policy and compliance document synchronization
