Harness
It's just the harness.
Planisphere doesn't build AI. It wraps the Claude Code and Codex you already use with memory, boundaries, sign-off and records. It starts on your Mac.

The difference
The model does the work. The harness keeps it on track and on record.
Your agents, your accounts, your models. Planisphere doesn't replace them.
What surrounds them: what they remember, where they cross, who signs off and what gets recorded.
On your Mac
Memory and steering, free, no account.
Codex and Claude Code share memory on your Mac. Context reaches them as plain prose, with no account needed.
See every Claude Code and Codex session on this Mac and who started whom. Leave a note for the next turn, or send it now.
Checkpoint, compare and restore. Your notes and their history stay on this Mac, with no Git repository needed.
Planisphere connects through Claude Code and Codex hooks, so you keep working the way you do now.
Steering is new in 0.10.0.
Boundaries
See what crossed, and who guarded it.
Seven starter boundaries: Production, Main branch, Permissions, Secrets, Shared systems, Money and Delivery. Each starts at Watch.
| Rung | What it does | Today |
|---|---|---|
| Watch | Record and seal every crossing. | Live: crossings come from agent transcripts |
| Flag | Raise the crossing for a named person to review. | Not yet: the gate has no Flag outcome today |
| Hold | Pause the crossing until a guard approves it. | When your system asks the gate API first |
| Wall | Refuse the crossing outright. | When your system asks the gate API first |
Boundaries observe today. Draft a policy and backtest it against crossings already recorded. Drafts aren't saved or enforced yet.
Sign-off and records
Proof you can hand to someone else.
Each review decision is sealed as its own receipt, attributed to whoever is signed in.
Once your Mac is connected to a console workspace, work that runs through Planisphere is sealed as a record you can open later.
Anyone can check a receipt.
Download records as one package. Each bundle verifies offline on its own.
A record shows what was recorded and sealed. It is not a legal finding or a certification.
For your team
Starts at home, grows into the console.
The Mac app is free for anyone. The console is where a team keeps records, proofs and organizations: 1,000 free credits every month, then 1¢ a credit, never more than $25 per action.
Questions.
Is Planisphere an AI model?+
No. It's the harness around the agents you already use. The Mac app can also run a small model on your Mac for local support. That's optional, and its savings haven't been measured.
Which agents does it work with?+
Claude Code and Codex on your Mac today.
Does it stop an agent from doing something?+
Not by itself. Boundaries observe and record. An action is held or refused only when your system asks the gate API before acting.
