3 Years Building a CLM. Here’s Why We Stopped and Why We’re Open Sourcing the Best Part.

We spent the last 3 years building a CLM with AI. We did everything, drafting, review, and data extraction. We put a lot of work into making the AI accurate and adding citations so people could actually trust it.

But we recently realized the world doesn't really need the full tool, so we’re stopping. Instead of letting the code go to waste, we open-sourced the contract review part.

When we built it, we focused on trust. We didn't want another "chat with PDF" tool that just sounds smart but hallucinates. So we added a feature where the AI has to show exactly which clause it’s looking at. No source link, no answer.

It also works with multiple files (like amendments or annexures) because contracts are usually messy and spread out over different documents.

So we released LexReviewer. It's open source now.

Repo: https://github.com/LexStack-AI/LexReviewer

Check it out if it’s helpful for what you're building. Let me know if there’s anything else from our old project you'd want us to release!
