hand it a job that takes days. it works your computer while you check in, give direction or take over — and when you log off, the project keeps moving.

the bottleneck

managing agents is a job now.

today, you carry the context between tools, check every result and tell each agent what’s next. add more agents, and your attention runs out first.

long-horizon

one job. for days.

one agent researches the parts. another writes the tests. the board is routed in an engineering app on your computer. t1 keeps all three on the same job.

every agent on the job, and the step it’s on — check in or take over any time.

access

know the step. reach the app.

an agent that can’t reach the app is stuck. your computer sees t1 as a monitor plus a usb keyboard and mouse, so your agents can watch the screen, type and click. add the cosein app on your mac and it does more.

self-improving

it gets better at your work.

it learns from each job, and the steps you keep become skills. the next job doesn’t start from a blank prompt.

coordination

an agent that manages your other agents.

it decides what’s next, hands results between them and checks the work. on t1, you give direction and review the decisions that matter.

what keeps the job moving.

coordination

one agent keeps track of who does what, and in what order.

project context

a decision made in one tool still counts in the next.

days, not sessions

a session ends. the job doesn’t.

screen and input

the screen comes in. keys and clicks go out.

take over

steer it, or do the step yourself.

reviewed skills

a procedure you’ve reviewed is one it can repeat.

in your hand

where the job stands, on t1’s own screen.

one press

anything irreversible waits for you. nothing else does.

a short list.
