What the category sells
A chat window
Most “private AI” for people is still a $20–$200 seat.
THE CATEGORY
What they sell. What we ship.
The market
The market sells private AI as a chat window with a privacy toggle. Literacy is prompting a rented model. The loop lives on someone else’s computer.

HOW TARX WORKS
How TARX works for people and small teams
01
Join on the Mac you have
TARX-OS seats are $0. First-run stays local. Nothing attaches until you opt in.
02
Run one real goal
Conversation is how you talk to it. The runtime stays on — Spaces, Control, Evidence.
03
Approve the write
Consequential actions wait on Deny or Allow once. Read Evidence after. That is literacy.
04
Add silicon if the desk needs it
Get a T-4 for indoor or vehicle work when shared work outgrows the laptop. Same OS.
Start on the Mac each person already owns. TARX-OS seats are $0. First-run stays local. Conversation is how you talk to it. The runtime stays on: Spaces, Control, Evidence.
Most teams only know chat seats. Put a real goal through Deny or Allow once. Read Evidence after. That is the product — not another subscription window.
When shared work needs dedicated NVIDIA, get a T-4 for indoor or vehicle work, indoor / vehicle. Same OS. Same approval. Join the Supercomputer. Or own Private Hardware.
THE WORK
WHAT PEOPLE ACTUALLY RUNS.
Daily work that cannot leave the laptop
Drafts, files, and context stay on this Mac. LOCAL by default.
A team that already has Macs
Same OS on every seat. No per-person license. Supercomputer only when shared work needs more.
Approval before a write
Consequential actions wait on Deny or Allow once. Evidence after.

| All-Pro floor | $100/mo | Still a seat. Still a hop. |
| TARX-OS | $0 | Always-on runtime on Macs you already own. |
| T-4 Supercomputer | $183/mo | Dedicated NVIDIA on the desk. List ÷ 36. |

What does a typical team spend on Claude instead?
Typical mix is 80% $20 seats and 20% $200 seats, counted as whole seats. Five people: 4 × $20 + 1 × $200 = $280/mo. All-Pro floor is 5 × $20 = $100/mo. A T-4 is $6,600 ÷ 36 = $183/mo.
When do we need a T-4?
When the team outgrows the laptop and needs dedicated NVIDIA capacity on the desk.
