Why Legerly

The information
gap is real.

When you use an AI product, the provider knows everything. You know almost nothing. That's not how markets are supposed to work.

01

Hidden costs

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

Opaque subscriptions

$20/month sounds reasonable — but is it? Without knowing your usage, you're guessing. Our tools give you the data to decide.

03

Environmental blind spots

AI uses significant water and energy. None of the major providers show you this. We do.

04

No neutral comparison

Every model comparison is written by someone selling something. We're not. Legerly tools are ad-free and have no affiliate relationships.

"Markets work best when both sides have the same information. AI isn't there yet. We're here to bring that to you."
