Bring Claude Code, Codex, GitHub Copilot CLI, Gemini CLI, and Pi usage into one place. See estimated costs by developer, project, repository, and model, with Git history behind the numbers.
Inspect captured usage allocated to recorded commits, branches, and pull requests, alongside estimated AI costs.
Review comparable work in your ledger, then make your own scope and budget assumptions. The illustration shows a manual comparison; Overview offers a calendar-period projection: simple extrapolation of estimates, not a bill or a forecast model.

Centrail collects usage and Git metadata. Your prompts, completions, code, and diffs stay out of the usage upload. Choose which repositories are shared with your team.
No SDK. No application code changes. No proxy. Install the Centrail CLI on the device you want to track, connect your free account, and sync supported agent logs. Your usage, costs, and Git history come together in your ledger.
Getting started: connect your first device ↗See environmental estimates alongside your AI usage and costs. Explore the assumptions and ranges through Centrail’s public methodology.
“Arguably the most important change will come from speeding up the transition to clean energy, and boosting the amount available so that demand for greener AI does not gobble up the low-carbon electricity also needed to decarbonise other sectors, from transportation to construction.”
Input, output, cache-read and cache-write tokens in the current selection. Counts do not establish capture completeness.
0 of 1,600,000 recorded tokens use the unknown-model default energy factor (1.0×; range 0.2–1.67×). Factor coverage is separate from pricing coverage.
Straight answers about capture, privacy, team sharing, and the numbers in your ledger.
Create a free account, connect the device where you code, and sync supported local logs. Team members connect their own devices and choose which repositories to share.
How team numbers work ↗No. Usage uploads contain tokens, model information, and allowed Git metadata, not prompts, completions, source code, or diffs. Repository names and commit identifiers are metadata, so choose the repositories you sync and share.
Read the privacy policy ↗Supported local logs supply usage context, and Git supplies repository and commit evidence. Centrail uses that evidence to allocate usage. Activity without a usable match stays visible rather than being forced into a commit.
Explore Git attribution ↗Costs are estimates over captured usage. PR and branch views are personal and follow the selected usage dates. Use the record to investigate the work and pricing behind a number.
Understand cost and linked work ↗GreenAI uses captured tokens, model assumptions, and environmental factors to estimate a footprint. The dashboard shows ranges and links to the public methodology.
Read the methodology ↗Yes. Tell us which agents you use, how your team works, and the question you need answered. You can request a feature or arrange a founder demo without sending private logs or code.
