Legerly
AI companies know exactly what your conversations cost. You don't. We're fixing that — one tool at a time.
What we build
Every Legerly tool answers a question AI providers won't. Free, privacy-first, and built for people who actually use AI every day.
See what every AI conversation costs — tokens, dollars, water — in real time, right in your browser. Turn on usage tracking and export your numbers straight into the Subscription Auditor for a plan recommendation based on how you actually use AI, not a guess.
● Live on ChromeLive pricing across every major AI model, updated weekly. See exactly what you're paying per token before you commit to a model or subscription.
● LiveA live, ticking tally of what the world's AI runs on every second — prompts, energy, water, and dollars. Each unit gets cheaper; the total keeps climbing anyway.
● LivePaste your text, pick your model, and see exactly how much context window you're using. No more mystery limits mid-conversation.
Coming soonAnswer a few questions about how you use AI and get a clear recommendation on which plan, tier, or provider actually makes sense for you.
● LiveAn independent scorecard of how openly each major AI company discloses the water and energy footprint of its data centers — graded 🟢 / 🟡 / 🔴, with sources.
● LiveA neutral, ranked comparison of AI models by price-to-performance. No ads, no affiliate links. Just the data you need to pick the right model.
Coming soonWhy Legerly
When you use an AI product, the provider knows what it costs to serve you. You're left guessing. That asymmetry isn't a minor annoyance — it's how the value AI creates quietly flows to a handful of companies instead of the people using it. Our tools hand that information back.
01
Token pricing is buried in documentation. Real-time cost during a conversation? Nowhere to be found. We show it to you as you type.
02
$20/month sounds reasonable — but is it? Without knowing your usage, you're guessing. Our tools give you the data to decide.
03
AI uses significant water and energy. None of the major providers show you this. We do.
04
Every model comparison is written by someone selling something. We're not. Legerly tools are ad-free and have no affiliate relationships.
"AI companies can see exactly what your prompts cost — in dollars, energy, and water. You can't. We build the tools that close that gap."
Legerly — independent, ad-free, and honest about what we don't yet know.
