Stele
Stele is a hosted, invite-only shared memory (agentic ledger) for AI coding agents that provides a live project record of decisions, tasks, lessons and risks which every agent reads before acting and writes back to as it learns.

Stele
Stele is a hosted, invite-only shared memory for AI coding agents: a live project ledger that records decisions, tasks, lessons, risks and provenance. Every agent reads this project record before it acts and writes back what it learns, so the project context persists across tools and sessions. Stele is aimed at development teams and their agents: tasks belong to the project (not a person), agents claim work atomically to avoid duplicated effort, and the system surfaces prior decisions and risks during work to prevent repeated mistakes. The product is provided as a hosted service with a CLI installer and is currently invite-only beta.
Shared memory for AI coding agents — Claude Code, Cursor, Codex. Decisions, tasks, and lessons in one shared record.

Claim this listingKey Features
Shared project ledger (project memory)
A live record of decisions, tasks, lessons and risks that every agent reads before it acts and writes back to as it learns.
Atomic task claiming & coordination
Tasks belong to the project and are claimed atomically so two agents never start the same work; operators can read the open queue and hand off work between sessions.
Agent integrations / MCP compatibility
Plugs into common coding agents (e.g., Claude Code, Cursor, Codex) and any MCP-compatible client through the hosted server so multiple tools read/write the same graph.
Self-maintaining graph
Stale entries are flagged, resolved risks retire, duplicates surface, and agents re-verify facts against live code so the record remains trustworthy.
Provenance & traceability
Trace why anything exists by walking from a decision back to the task, document, risk and the person who made the call.
Built-in assistant
A project assistant answers from the live graph for status, history and where to start, with context already loaded.
Hosted service with CLI
Hosted product requiring no infrastructure to run; a one-line installer provides the stele CLI to sign in and seed a project record.
Privacy controls
Data is private per project, not sold or used to train models without consent; users can export or delete their project data.
Pricing

Use Cases
Catch returning bugs
When a change risks reintroducing a past problem, the linked risk surfaces while work is happening so the agent can pause and ask instead of guessing.
Cross-agent continuity
Plan with one agent and build with another; multiple agents read and write the same graph so work continues when switching tools or sessions.
Team coordination & handoffs
Operators can pick up the open queue, run tasks end-to-end, and write handoffs so the next session resumes with full context.
Onboarding contributors
Point Stele at an existing repo to map code and docs into the record, making new human or agent contributors productive from day one.
Integrations
Claude Code
