# Time Momentum > Hours no longer measure the value of AI work. Time Momentum shows what really goes into your projects. Time Momentum is the CRM for people who work with AI agents every day: it captures the effort behind AI work per client and project, carries it through to the e-invoice and can be operated entirely by your own agents. Time Momentum records working time, AI agent runtime and tokens from Claude Code, Codex and Cursor per project, values them in euros and carries them through to client reports, invoices and fixed-price costing. Sign up: https://app.time-momentum.com/signup. Agents use the command line `tm` (npm package @time-momentum/cli) or the REST API; `tm schema --json` lists every command. ## Setup for agents - [Set up the agent collector: install tm, the human connects with tm collect init](https://www.time-momentum.com/agents/collector.md) - [Set up the command line tm: install, the human signs in with tm auth login](https://www.time-momentum.com/agents/cli.md) - [REST API as OpenAPI 3.1 (descriptions in German)](https://www.time-momentum.com/openapi.yaml) ## Product - [Home](https://www.time-momentum.com/): Time Momentum is the CRM for people who work with AI agents every day: effort per client and project, through to the e-invoice, run by your own agents. - [Effort](https://www.time-momentum.com/usage-tracking): AI sessions from Claude Code, Codex and Cursor plus your working time, captured automatically per project and client and valued in euros. - [Billing and costing](https://www.time-momentum.com/project-profitability): Value of work, revenue, costs and margin per project and client.
