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.

Key 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

Reads and writes the shared project graph so it has project context.

Cursor

Integrates as a coding agent that shares the same project memory.

Codex

Works with the shared graph to maintain continuity across sessions.

Antigravity

Supported coding agent integration that reads/writes the project ledger.

Copilot / OpenCode

Coding agents that can read and write the project's shared memory.

Grok Build

Agent integration for reading and writing the project record.

Kimi Code CLI

CLI-based agent integration option.

Any MCP-compatible client

Supports any MCP-compatible client through the hosted server.

Benefits

Provides continuity across tools and sessions so project context belongs to the team, not a single tool.
Reduces repeated mistakes by surfacing prior decisions, risks and lessons during work.
Simplifies coordination by making tasks project-level and claimable atomically.
Hosted, no infrastructure to operate; quick CLI-based onboarding.
Privacy-first: project data stays private, with export and deletion controls.

Limitations

Invite-only beta: access requires joining the waitlist; sign-in works only once you're invited.
Managed (hosted) product today; self-hosted/open SQLite-backed version is planned but not yet available.

Frequently Asked Questions

What is Stele?
Stele is shared memory for AI coding agents — one record of your project's decisions, tasks, and lessons that every agent reads before it acts and writes back to as it works.
Which AI agents and tools does it work with?
Claude Code, Cursor, Codex, Antigravity, Copilot, OpenCode, Grok Build, and Kimi Code CLI — plus any MCP-compatible client and the stele CLI.
How do I get access? Is it invite-only?
Yes — Stele is invite-only while we open up gradually. Join the waitlist at stele-ai.dev and we'll email you the moment a spot opens.
Can't I already do this with Notion, Obsidian, or a file in my repo?
You can store notes that way, but they are written for humans and go stale. Stele is read and written by agents automatically on every prompt and keeps itself honest by flagging stale facts, retiring resolved risks, and preventing reversed decisions from being served as truth.
Why pay when free, open-source graph and RAG tools exist?
Open tools provide a store or retrieval library, but you still must wire and operate the loop yourself. Stele provides the hosted, cross-agent loop (read before prompt, write mid-task, claim tasks, maintain freshness) out of the box; an open, SQLite-backed self-hosted version is planned.
Is my code and data private?
Yes. Data is private per project, never sold or used to train models without your say-so; your source code stays on your machine. You can export or delete everything yourself at any time.
Do I have to run any infrastructure?
No — Stele is hosted, so there's nothing to run. Install the CLI, sign in, and point it at a project.

Getting Started

  1. 1 Step 1: Join the invite-only beta via the waitlist at stele-ai.dev and sign in with the invited email.
  2. 2 Step 2: Install the stele CLI (one-line installer shown on the site) and sign in with your invite email.
  3. 3 Step 3: Inside your agent, run /stele:start to let Stele wire into your project and build the initial record; then continue working as before.
