Every prompt has a footprint.
We're building the ledger.
Token Offset is the first platform built to account for the environmental cost of artificial intelligence: for individuals who want to use AI without the guilt, and for organizations getting ahead of what's coming.
AI is the fastest-growing line item on the planet's power bill, and almost nobody is paying for it.
Data centers, driven mostly by AI workloads, are projected to consume by 2030, rivaling small industrialized nations.

To offset what their prompts cost the grid, the watershed, or the atmosphere. Until now, no easy way existed.
“The greatest threat to our planet is the belief that someone else will save it.”
Estimate. Price. Offset.
A clear, audit-friendly loop. No black boxes, no marketing math. Every dollar maps to a measurable intervention.
Estimate your usage
Pick the band that fits, from Casual to Extreme, or paste an Anthropic or OpenAI admin key and we'll sample your last 3 months. Token counts only; we never see your prompts.
See what that costs the planet
We turn your estimated tokens into Wh, mL of water, and grams of CO₂ using transparent, peer-reviewed coefficients we publish openly.
Cover it monthly
A single subscription routes funds to vetted carbon removal, watershed restoration, and grid decarbonization projects, with receipts.
Where do you fit?
AI usage spans six orders of magnitude across users. We calibrated four bands against public studies, operator disclosures, and real agent traces so the math feels true to your reality.
Occasional questions to Claude and ChatGPT
A few thousand tokens on use days, or roughly a few dozen short conversations per month.
Average human knowledge worker, daily AI use
20,000 to 250,000 tokens per workday for writing, research, analysis, and repeatable GPT/project workflows.
Coding agents and multi-step workflows
Hundreds of millions of tokens per month for daily coding agents, long-context tasks, retries, and context replay.
Internal devs, eval pipelines, agent fleets
Up to 210 billion tokens in a single week at the very top of the distribution.

Whether you're one person or ten thousand, the math is the same.
Use AI without the quiet guilt.
If you've ever paused before sending a 200-message thread to ChatGPT, this is for you. Pay a transparent monthly contribution and know that the carbon, water, and load you generated are accounted for.

Get ahead of the regulation that's coming.
The EU AI Act has begun naming environmental disclosures. California, New York, and the UK are circling. The companies that build offset infrastructure now will define the standard, and avoid retroactive compliance scrambles in 2027.
- Org-wide gateway, SSO, RBAC, audit log
- Quarterly attestations for ESG reporting

No greenwashing. No vibes-based credits.
Just receipts.
Transparent coefficients
Our energy, water, and emissions estimates are published with sources and revised quarterly. Nothing is invented to make a graph look impressive.
Verified offsets only
We allocate to vetted, registry-backed climate projects, with bias toward durable removal (mineralization, biochar, DAC) over avoided-emissions credits.
Customer-owned data
We never see, store, or train on your prompts. We measure usage at the token-count level. Nothing more.
Receipts you can show
Every dollar maps to a project with a public registry ID. Your annual report doubles as a regulatory artifact.
Ready when you are.
Token Offset is in private beta. Reserve your spot in 30 seconds, no payment required today.
