// the problem

Legal professionals rely on black-box AI they can't own, share, or monetise. There is no marketplace of legal AI workflows. Students struggle to build portfolios as firms prioritize automation. If big companies own all the datasets and workflows, a legal counsel won't be needed at all in the future.

Them — Closed

Owned by big company and their investors — not the legal specialist
Not collaborative
Black-box, no traceability
Vendor lock-in, no export
Big company, seeking profit, won't go in smaller countries

QueryLex — Open

You own your models, workflows, datasets
Fork, share, collaborate on GitHub
Transparent, traceable reasoning
Download locally, export anytime
Earn revenue when others use your workflows

💸

Earn revenue from your expertise

Share your workflows on the marketplace. Every time another user runs your workflow on the platform, you earn a share of the revenue. Your legal expertise becomes a product.

🔍

Transparency, not black box

Custom models with traceable reasoning. Not a generic AI query engine — a legal specialist ecosystem focused on workflows and ownership.

🌍

Horizontal, not gated

AI will not replace lawyers — lawyers who harness and own AI workflows will replace those who don't. Workflows and owned datasets become the real competitive moat.
