A verifiable shared context layerfor your project and every AI tool that touches it.
Aira’s Project Ledger turns your project’s state into a verifiable shared context layer — every claim is evidence-backed, every change is auditable, and every AI tool you use can read it.
- Drift detection
- A verifier called Guardian continuously checks Aira’s view matches reality. No more “Aira’s outdated, my code says something else.”
- Live context for your AI tools
- Aira writes your project’s state to plain-text files on disk. Claude Code, Cursor, your custom CLIs — they all read the same source of truth.
- One audit trail for everything
- Every event in your project — a Slack message, a GitHub PR, a task update — flows through one ordered log. Trace any claim back to its source in seconds.
What your AI tools see.
When you connect Aira, a structured snapshot of your project lands on disk and over MCP. Plain text, easy to read — for you and for any agent.

Where the Project Ledger sits in the Aira platform.
The Project Ledger is the first of four pillars. The other three read from it and write back to it, so everyone on your project builds from one verifiable reality.
Pillar I · You are here
Project Ledger
Evidence-backed truth in ~/.aira/context/ and over MCP, with Guardian checking it against your codebase.
Pillar II
Intelligent Project Orchestration
Turns intent into Living PRDs and capacity-sized sprints, written straight into the Ledger.
Explore orchestrationPillar III
AI Agents
Nine specialist agents and AI team members that read the Ledger before they act.
Meet the agentsPillar IV
Agent Workspace Fabric (AWF)
Runs coding agents in isolated worktrees grounded in the Ledger, merging through one governed queue.
