The problem

Your AI bill is one number with no story behind it.

  1. A single monthly invoice, zero attribution.
  2. No idea which repo or team is burning the tokens.
  3. Spikes land on the bill, not in real time.
  4. No way to tie spend to a feature, branch, or ticket.
  5. Budgets blown days before anyone notices.
What makes it different

See spend the way you organise work.

Most tools hand you one number. Lineman attributes every dollar of AI spend to the repository, developer, and branch it came from, so you know exactly where the cost went.

Real-time

Catch a cost spike in minutes, not on the invoice.
