Comparison
Generic AI is great for many things—but analyzing legal documents isn't one of them. Here's why.
ChatGPT regularly "hallucinates" legal citations—confidently citing laws that don't exist or getting statute numbers wrong. For your housing and money, that's a dangerous gamble.

"California limits security deposits to 2 months' rent for unfurnished units."
Wrong. As of July 2024, California AB 12 limits deposits to 1 month's rent. ChatGPT's training data predates this law.
"California limits security deposits to 1 month's rent under AB 12, effective July 1, 2024."
Correct. With a clickable link to the actual California Civil Code section.

ChatGPT can read your lease and provide general observations, but it lacks real-time state-specific legal knowledge. It may cite laws that don't exist, miss state-specific protections, or give advice that's wrong for your jurisdiction. For something as important as your housing, this risk isn't worth taking.
Honestkey is purpose-built for lease analysis with a legal knowledge base updated with all 50 states', U.S. territories', and federal landlord-tenant laws. ChatGPT is a general-purpose AI trained on internet data with a knowledge cutoff, meaning it doesn't know about recent law changes and often 'hallucinates' legal citations. Each violation Honestkey flags names the statute behind it and is checked a second time against that statute.
ChatGPT has a free tier, but the free version is less capable. ChatGPT Plus costs $20/month. Honestkey starts at $19.99 per lease for the full analysis, with a free preview. The difference is Honestkey is specifically designed for this purpose, with a statute citation for each violation it flags.
Yes! Once Honestkey identifies specific issues and cites the relevant laws, you can ask ChatGPT general questions about concepts. Just don't rely on it to find the issues in the first place or to know your state's specific rules.
