Think hard. Prompt light.

AI is useful but the AI industry is reckless. TreadLightlyAI is a thinking tool for people who want AI's capabilities without ignoring what it costs.

Slide 1 of 5: Thinking modes
TreadLightlyAI on a laptop and a phone: a research answer with citations, a teaching conversation, and the energy each one used shown under the reply
A plan-mode conversation about cutting a data pipeline's energy use, with a monthly energy report card: renewable-powered models took 4 of every 5 calls, about a few phone charges in total
Challenge mode pushing back on a four-day work week plan, with the conversation list on a phone alongside
A project workspace for a volunteer tool library: its standing instructions on a laptop, with the project's notes and conversations as overlapping cards
A conversation shared as a public web page, open on a laptop and a phone, with a note saying its content was written by a user and an AI

Thinking modes

Each mode changes how the AI approaches your prompt. Balanced, Challenge, Research, Write, Teach, Plan, and Audit.

Real-time cost tracking

Every prompt has an energy and token cost. We show you both, on every message. Knowing what you spend changes how you prompt.

Green infrastructure

Hosted in Infomaniak's Geneva data center, which recovers 100% of the electricity it uses as heat for 6,000 homes. Their data centers run on local renewable energy at an annual PUE below 1.1, cooled by filtered outside air instead of refrigerant.

10% to AI safety

10% of all revenue funds AI safety research and advocacy, disbursed every six months and posted on our transparency page. Not a pledge. A line item. The risks of poorly aligned AI are real and present.

What is TreadLightlyAI?

TreadLightlyAI is a responsible AI thinking tool for people who want AI's capabilities without ignoring what they cost: energy, money, and societal risk. We run small and medium AI models on renewable energy infrastructure and show real-time energy and token costs on every response. We deliberately exclude energy-intensive options like image generation and frontier models. We also offer Claude's small and medium models from Anthropic, because Anthropic has shown stronger commitment to AI safety than most of the industry. Every prompt routes through one of our thinking modes, designed to sharpen reasoning quality rather than just return fast answers. 10% of every subscription funds AI safety research and advocacy.
