Sovereign Sheets

Your Data. Your Rules.

Overview

Sovereign Sheets is an open-source, privacy-first spreadsheet and data platform designed to provide the capabilities of spreadsheets, databases, business intelligence platforms, automation systems, collaborative workspaces, and AI-powered productivity tools within a single modular system.

The platform is designed around user ownership, data sovereignty, interoperability, extensibility, local-first operation, and encryption throughout the data lifecycle. Sovereign Sheets enables individuals, businesses, researchers, organizations, educators, developers, and communities to create, manage, analyze, visualize, automate, and collaborate around structured and unstructured data.

Sovereign Sheets uses a modular architecture in which core platform capabilities provide shared infrastructure and application-specific capabilities are implemented through specialized modules and AI agents. Optional plugin modules extend the platform without requiring application-specific functionality to become part of the core.

Core Architectural Rule

Sovereign Sheets must maintain a clear separation between platform infrastructure and application-specific functionality.

Core modules provide reusable capabilities.

Application modules provide specialized functionality.

AI agents provide intelligent application assistance.

Optional plugins provide extensibility.

Integrations provide external connectivity.

AI models provide interchangeable intelligence.

No application-specific feature should be placed into the core solely for convenience when it can be implemented as an independent module or plugin.

User Experience

The interface should provide a unified workspace while allowing users to discover capabilities progressively.

Interface Capabilities

Spreadsheet interface
Database interface
Natural-language interface
Agent interface
Dashboard interface
Workflow interface
Form interface
Search interface
Documentation interface
Plugin management interface
Permission management interface

Collaboration interface

Users should be able to accomplish complex operations through traditional interfaces, natural-language commands, or a combination of both.

Data Storytelling

Sovereign Sheets should allow users to transform structured data into understandable presentations.

Capabilities

Automated summaries
Narrative reports
Interactive dashboards
Charts
KPI summaries
Trend explanations
Comparative analysis
Executive summaries
Report generation
Presentation-ready outputs

Reversibility and User Control

Where technically feasible, actions that modify user data should support:

Preview before execution
Confirmation
Undo
Redo
Version restoration
Change history
Action logs
Rollback
Selective reversal

AI-generated modifications should be distinguishable from manually created changes.

Open Source Requirements

Sovereign Sheets is intended to be developed as open-source software.

The project should prioritize:

Transparent source code
Open development
Public documentation
Community contributions
Auditable security
Interoperable formats
Extensible APIs
Portable data
Self-hosting
Vendor independence

Future Expansion

The modular architecture must allow Sovereign Sheets to expand without requiring fundamental redesign of the platform.

Future modules may provide:

Additional application agents
Additional AI models
Additional database engines
Additional visualization systems
Additional integrations
Additional industry applications
Additional storage systems
Additional synchronization mechanisms
Additional collaboration systems
Additional automation capabilities
Additional privacy technologies

The platform should remain capable of evolving as new technologies, workflows, data formats, AI models, and user requirements emerge.

Project Goal

Sovereign Sheets aims to provide a comprehensive open-source environment for working with data, information, calculations, analysis, automation, and AI.

Rather than limiting the platform to traditional spreadsheet functionality, Sovereign Sheets combines spreadsheet capabilities, databases, specialized AI agents, natural-language interaction, analytics, visualization, automation, forms, collaboration, integrations, and extensibility within a secure modular architecture.

The system is designed so that users can begin with a simple spreadsheet and progressively add databases, dashboards, workflows, agents, integrations, and specialized application modules as their needs grow.
