For macOS · local-first · one agent
One continuous conversation with an agent that learns you. It drives the same surfaces you do: the browser tab you’re in, a real terminal, a serious block editor. Bigger jobs automatically fan out to background sub-agents, each with its own isolated off-screen browser and terminal, all watchable live. Everything stays on your Mac.
Spaces · Libraries · Projects
Writing journals. Growing social media accounts. Running online stores. A space is the room you walk into, with its own theme, vibe, and agent flavor, scoping what Partner sees, what it remembers, even which tabs sit open. The rooms change; the relationship doesn’t.
The finished draft. The signed contract. The final cut. A library is the space’s shelf: the work worth keeping, promoted up out of the mess and curated by you alone. You manage the shelf; the agent must ask.
Prep the talk. Launch the store. Plan Q4. A project is a goal in motion, with an Overview, a Todo board, and internals that stay messy so your space doesn’t. Archive it when it’s done. The agent manages the mess; you read the outputs.
What it does
No thread list, no “new chat” decision. You text Partner the way you text a person. The past comes back as ⌘K memory answers with sources, not transcripts to scroll.
Real Chromium, embedded. You and the agent share the same tabs, sessions, and logins. Hand a page over, or grab it back. Background work browses off-screen, in the agent’s own isolated browser.
Partner fans big jobs out to sub-agents, each isolated with its own browser and terminal. Watch the whole tree live: each agent’s current tool, terminal log, and browser screencast. Redirect or cancel any of them.
Before handing work to a helper, the agent proposes a task card with the goals and what you’ll review at the end, then waits. Nothing spawns until you say so.
Notion-parity blocks (slash menu, callouts, tables, to-dos) that round-trip losslessly to plain Markdown on disk. Select a passage and ask the agent to revise it in place.
One command bar for everything: search across every space, ask what Partner remembers, switch spaces, open files and terminals. ⌘P fuzzy-finds any file in the active space.
Trust & control
Read-only actions just work. Anything side-effecting waits in a queue of things blocked on you: approve, edit, or decline.
While the agent is mid-task, the browser and terminal show one button: Stop the agent / Take control.
The agent works freely inside projects, and is locked out of your Library. Approval-gated promotion is its only way onto your shelf.
Bring your own API key. Stored on your Mac, never on our servers. There are none.
Everything Partner remembers lives as plain markdown in a single folder.
Spaces are the interface; the folder is the truth. Open it in Obsidian or VS Code.
git init it. Sync it on your own remote. The database is just an index
you can drop and rebuild. No SaaS lock-in.
