THE WORK BEHIND THE NUMBERS

Explore the usage allocated to your Git work.

Inspect captured usage allocated to recorded commits, branches, and pull requests, alongside estimated AI costs.

PLAN WITH HISTORY

Use historical costs to inform your next budget.

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.

YOUR WORK. YOUR BOUNDARIES.

Your prompts and source code stay yours.

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.

THE FOOTPRINT BEHIND THE WORK

Estimate the energy, water, and carbon footprint of your AI usage.

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.”
The Economist, “The tricky task of calculating AI’s energy use” (2025)

1,600,000 recorded tokens · per-model split

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.

A FEW GOOD QUESTIONS

What do you want to know?

Straight answers about capture, privacy, team sharing, and the numbers in your ledger.

How do I track coding-agent usage across a team?

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 ↗
Do you upload my prompts or source code?

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 ↗
How does Centrail connect AI usage to Git history?

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 ↗
How should I read costs by project, PR, or branch?

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 ↗
Where do the energy, water, and carbon estimates come from?

GreenAI uses captured tokens, model assumptions, and environmental factors to estimate a footprint. The dashboard shows ranges and links to the public methodology.

Can I request a feature or talk about my team's workflow?

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.
