TEAM HARNESS · BUILT FOR COLLABORATION
A team Harness built for collaboration
Every task is planned, executed, and reviewed the way your team works—with visible progress, human approval for critical actions, and safe rollback.
01 — Every work surface
At home with any kind of work
Hand the work to TabTin and it picks the right surface itself: writing code, drafting documents, organising data, digging through research — all on one workbench, so you never explain the context twice.
02 — Group collaboration
People and Agents, move work forward in one group
Agents find issues in group messages, create tasks, and @owners. Progress and results sync back automatically.
03 — Shared task
An Agent conversation shared by a friend, open it and keep talking
Share a task with a friend in a direct message. They can open the complete conversation on the right, review its context and deliverables, and continue with Agent from where it left off.
04 — Projects
Tasks, owners, and results all live in one project
Everyone knows where the work stands and who owns the next step, while important content stays together.
05 — AI avatar
An AI avatar that understands you, keeps working your way
Define its role and rules, then equip it with memory, skills, and tools. It can take on recurring work and carry your judgment from one task to the next.
06 — Keep going
Switch devices and keep going
Move work forward on your computer, then check, reply, and approve from your phone. Work keeps going when you leave your desk.
07 — Organization settings
Members and quotas, clear in one place
Give each member an AI quota, follow usage as it happens, and get warned before anyone runs out.
