The AI Workspace That Actually Belongs to You
Stop renting your intelligence. Tandem is the local-first, zero-trust AI workspace designed for deep work, not just chat.
Native Intelligence
We don't just pass messages to an API. Tandem features a built-in vector database and long-term memory engine that runs locally. It learns from you without leaking your data.
True Ownership
Your data lives in a secure, encrypted vault on your drive. No cloud sync required. No "telemetry" spying on your ideas.
Infinite Extensibility
Turn Tandem into a Bio-informatics researcher, a Legal analyst, or a Screenwriter with **one-click installs** from our "Packs" library.
Powerful MCP Integration
We fully support the Model Context Protocol (MCP). Connect to any local or remote MCP server to give your AI direct access to your tools, databases, and internal APIs.
"If it speaks MCP, Tandem can use it."
The Open Alternative
You wouldn't let a stranger organize your physical desk; don't let a closed-source algorithm own your digital one.
Omnichannel Connections
Break out of the local sandbox. Connect Tandem seamlessly to external channels like Slack, Discord, and Telegram.
Manage persistent sessions and trigger workflows directly where your team collaborates.
Agentic Automation
Stop chatting and start delegating. Deploy specialized AI agents through the Agent Command Center to plan, execute, and verify complex tasks autonomously.
SEE TANDEM IN ACTION.
A beautiful, native interface designed for deep work. No complexity, just intelligence.

Smart Sidebar & Workspace Explorer
Premium Blackboard UX
Live decision spines, lineage rails, and context drift details shared across Orchestrator and Command Center workflows.
Agent-Team Fanout
Instantly scale operations with `/agent fanout`. Supports auto-switching from plan modes and rapid multi-agent task delegation.
Two-Pass Orchestration Planning
Complex objectives are processed through an analysis-first decomposition pipeline, significantly improving autonomous execution reliability.
Universal Providers
Configure any OpenAI-compatible API endpoint with auto-normalization, short-retry fallbacks, and persistent provider state.
Markdown Web Tools
New `webfetch` returns structured markdown by default, optimizing token usage and HTML-fallback comprehension for your agents.
External Channels
Connect Tandem to Slack, Discord, and Telegram. Manage sessions via specific slash commands (`/new`, `/resume`) and persistent user mapping.
Agent Command Center
Dedicated surface for Agent Teams with live mission visibility, approval gates, and a new Agent Automation workspace.
Mission Runtime
Engine-native orchestration. Define complex mission flows with shared resource blackboards and event-driven reviewers.
Self-Healing Substrate
Automatic stale engine replacement and managed-port fallback ensure the runtime recovers instantly from connection failures.
Governed Memory
Tiered learning architecture. Promote memories through rigorous scopes (Session, Project, Team, Curated) with full audit trails.
Global Stream Hub
Unified event substrate fans out events to Chat, Orchestrator, and Ralph with industrial-grade reliability and health signaling.
Sovereign Security
Provider keys are hardware-encrypted. Hardware-local execution ensures strictly sovereign data handling.
THE LOCAL-FIRST
AI ENGINE.
Most AI tools require you to hand over your data to the cloud. Tandem breaks this cycle. Using strictly local processing or point-to-point encrypted connections, your workspace stays where it belongs: on your machine.
Zero Telemetry
We don't track what you do, what you say, or what you build.
Supervised Operations
The AI never executes commands without your explicit one-click approval.
Verifiably Open
100% Open Source. Audit the code yourself. No backdoors, no exceptions.
A KNOWLEDGE PACK FOR EVERY ROLE.
Native Power Packs bring specialized capabilities to every department, now with enhanced Agent Teams, Blackboard visualization, and automated scheduling.
Marketing Core 9
Includes `seo-audit`, `social-content`, `launch-planning`, and 6 other canonical skills for complete market domination.
ChatOps Integrations
Manage sessions directly from Slack, Discord, and Telegram. Trigger mission templates and monitor bots remotely.
Finance & Legal
Automate reconciliation, draft NDA reviews, and perform SOX testing (`finance-sox-testing`) with strict isolation.
Sales Intelligence
Leverage `/agent fanout` to generate account research, prep for calls, and draft competitive assets in parallel.
Productivity System
Now with analysis-first two-pass planning and default `webfetch` workflows. A 'Deep Memory' system for tracking tasks.
Data Science
Validate datasets, build dashboard visualizations, and write SQL queries (`data-write-query`) automatically.
Enterprise Knowledge
Synthesize intelligence from vast document stores and manage knowledge sources (`enterprise-search-strategy`).
Design & Frontend
From theme generation to algorithmic art, transform text into visual components and web artifacts instantly.

"A mission to return power to the individual."
After many years contributing to open source code and using open source tools, I felt it was time to build something that solves a modern crisis: Privacy in the Age of Intelligence.
Tandem is my way of giving back. For the last two years, developers have had superpowers—automating tasks, generating code, and analyzing data. I built Tandem to give that exact same power to everyone else.
I wanted to take the raw potential of open source engineering and wrap it in a beautiful, completely visual interface that anyone can use. Zero coding required.
I only enjoy building apps that I will use and enjoy myself, so hopefully this brings joy and entertainment to others like it does for myself.
