Planisphere Desktop
Create your Universe.
Steering, memory and knowledge graphs for the AI systems you already use. Watch every Claude Code and Codex session, keep them current, and keep a record of what they did.
Every session, by project
Agents, tools, context, receipts
Name the project; agents fill the rest
Policies, laws, duties, evidence
Steering
Steer all your Agents at once.
Steering opens on a start page: your projects as night charts drawn from each knowledge graph. Open one in a half panel, full screen, or beside another.
- A line under every prompt shows what Planisphere added and did on that turn
- A note can wait for the next turn, or go now into Planisphere's Terminal
Connect
Connect your Agents, Tools, Context, and Policies.
Harness the power of AI with a unified system for you.
- Memory works without an account
- Each connection shows whether it's on, off or needs attention
- Connecting to a console workspace also installs activity recording for Claude Code
Projects
Name the Project. The agents fill the rest.
A project keeps what its agents may read and what they may do in one place: folders, knowledge graphs and memory on one side, boundaries and response checks on the other.
- Pick what a project can read, one connection at a time
- Set a response for each boundary: Watch, Flag, Hold or Wall
- Project rules are saved on this computer; enforcement is coming
Governance
The rules you work under, on one page.
Governance gathers your policies, the laws that apply, the duties they create and the evidence you keep. It starts with seven boundaries at Watch and the laws in Planisphere's corpus.
- Policies, laws, duties and evidence, each with a count
- EU AI Act Article 50, California SB 942, ABA Formal Opinion 512 and more
- Sealed receipts and the policy backtest under Evidence
Knowledge graphs
Your notes, with a way back.
Open a folder of notes as a knowledge graph. Take checkpoints, compare any two, and restore an earlier one into a new folder. Measure shows how the graph is linked.
Notes and their history stay on this computer. No account. No Git repository.
Download
What installs, and how to take it out.
Planisphere hooks into the agents you already run, so here is exactly what it adds to your computer.
Free · 0.10.17 (51) · Nov 8, 2026 · 48 MB
A Mac with Apple silicon, running macOS 14 or later.
Signed with an Apple Developer ID and notarized by Apple.
Checks for updates on its own through a signed feed. Installing one waits for you.
Adds Planisphere's hooks to Claude Code or Codex. Your other hooks and settings stay as they are. Claude Code may ask you to review the new hooks in /hooks.
Installs a local reader so your agents can read the knowledge graphs you open, with each one's exclusions.
Only if you choose it: a one-time 2.5 GB download, checked against a pinned fingerprint, run as a login item that answers only this Mac.
Remove any hook from Settings › Hooks, then quit Planisphere and move it to the Trash.

Release notes
What's new.
Keep every agent's memory in Planisphere, voices and helpers you turn on with one line, and two voice slots.
Global, corrected: memory as Markdown in your Global vault, a faster Global page, setup for your agents' own rules, and an editor that scrolls.
A markdown editor: open any note in a tab or its own window, write in the rendered text, and every edit is checkpointed.
Before you install.
