GLM-Legal is Z.ai's legal AI model for contract review and compliance. Pricing is not stated on its site — the product appears tied to Z.ai's AutoClaw platform, and there's no public price or free tier to compare against, which makes it hard to know what you'd actually pay.

Superlegal
Superlegal (site) combines AI contract review with human attorney verification, aimed at businesses that need both speed and a sign-off they can rely on. It's the closest match to GLM-Legal's compliance focus, and its 75 launch-day votes suggest real traction. Pricing is billed annually, starting at $999/mo for Essential, up to $3,499/mo for Premium. The honest limitation: there's no free tier, so you can't try it before committing to an enterprise-level budget.
Maigon
Maigon (site) is a legal AI built specifically for contract review, pitched at individuals and teams who need a dedicated model rather than a general-purpose tool. The Individual plan runs €690/month (about $575/month USD, billed annually); Team and Enterprise plans require contacting sales. It suits legal departments with a set budget for software. Limitation: no free tier and no monthly option stated, so smaller teams or solo users without annual budget approval may find it hard to justify.
Clause AI
Clause AI (site) goes beyond review into drafting and negotiation simulation, useful if you want one tool for the whole contract lifecycle rather than just checking existing documents. It offers a free trial, then $39/mo (Starter, 50 credits) or $99/mo (Pro, 150 credits). Good for teams that negotiate contracts often. Limitation: credits are capped per plan, so heavy users may burn through them before the month is up.
Smart Legal AI
Smart Legal AI (site) generates and checks contracts across 85 countries, which makes it a fit for businesses operating internationally. It has a genuine free tier (1 case analysis and 1 contract per month) plus a 14-day trial, with paid plans from $14.99/mo. It's a reasonable low-cost starting point. Limitation: the free tier is very limited (one contract a month), so it's really a taste-test rather than something you could run a business on.
ReviewMyContract
ReviewMyContract (site) is a straightforward AI contract review platform with a free tier (200 credits for 30 days) and a Pro plan at $9.90/mo for 2,000 monthly credits. It's the cheapest paid option here, suiting freelancers or small businesses reviewing contracts occasionally. Limitation: it's priced and scoped as a lighter tool than GLM-Legal's compliance focus — there's no mention of dedicated compliance features, just review.
Contract-AI
Contract-AI (site) is described simply as an AI-powered contract analysis tool, with no free tier and no pricing stated anywhere on its site. It's worth checking directly if you want a no-frills analysis tool and don't mind contacting them for cost. Limitation: with no pricing or free tier disclosed, you can't compare cost upfront, which is a real drawback next to competitors that publish their rates.
Agreement Detective
Agreement Detective (site) focuses narrowly on spotting hidden risks in contracts, with a free tier to start. No paid tier or pricing details are published. It could work as a quick first-pass risk check before deeper review elsewhere. Limitation: with no stated pricing and limited launch traction (2 votes), it's unclear how complete or actively maintained the product is.
How to choose
If you need compliance sign-off with human backup, start with Superlegal or Maigon, accepting the higher, enterprise-style cost. If you want to try something free first, Smart Legal AI, ReviewMyContract, or Agreement Detective let you test before paying. If you also need drafting and negotiation tools, Clause AI covers more of the contract lifecycle than a pure review tool.
