The 6 best Luminance AI alternatives to consider in 2025

So, you're on the hunt for a tool like Luminance. You're tired of the soul-crushing work of digging through dense documents and know there's got to be a smarter way than reviewing contracts line by line. I get it.

But here's an interesting thought. The problem Luminance tackles, finding that one crucial piece of information in a sea of text, isn't just a lawyer thing. Your customer support, IT, and HR teams are fighting the same battle every single day. They're just digging through support tickets and company wikis instead of legal agreements.

What if you could take that same AI magic and point it at your support queues or internal knowledge base?

In this guide, we'll look at the top direct Luminance AI alternatives for legal tasks. But I want to start with a different angle: a tool for teams who need that AI power not just in the legal department, but across the entire company.

What is AI contract review software?

At its core, AI contract review software uses fancy tech like natural language processing (NLP) to read and understand legal documents for you. It's kind of like having a paralegal who can read at lightning speed and never needs a coffee break.

These tools scan agreements to pull out important clauses, flag risky language, and spot weird phrasing that doesn't match your company's playbook. The big win here is pretty obvious: it saves a ton of time. Instead of getting buried in paperwork for compliance checks or due diligence, legal teams can actually focus on the stuff that requires a human brain.

How we chose the top Luminance AI alternatives

To put this list together, I looked for tools that do more than just show off a long list of features. I wanted to find products that actually solve problems without creating a bunch of new headaches. Here's what I was looking for:

• Does it actually work? Plain and simple. Does the tool deliver on its promises, whether that's contract review or answering support tickets?

• How painful is the setup? Can you get started right away, or are you looking at weeks of sales demos and begging your dev team for help?

• Can you make it your own? I looked for tools that let you adjust the AI's tone, control its knowledge sources, and set up workflows that fit your team's real process.

• Does it play well with others? The tool had to connect with the stuff you already use, like your help desk, Slack, or Google Docs.

• Is the pricing a mystery? I prioritized tools with clear, upfront pricing. Nobody likes getting a surprise bill.

The best Luminance AI alternatives at a glance

Here’s a quick rundown of the tools we’ll be looking at.

A closer look at the 6 best Luminance AI alternatives

Let's dive into what makes each of these tools a worthy alternative.

1. eesel AI

First up, let's look at something a bit different. While Luminance is hyper-focused on legal teams, eesel AI is built for businesses that want to use AI automation everywhere. It hooks into the tools your team already lives in, like Zendesk, Slack, Confluence, and Google Docs, to handle customer support, answer internal questions, and pull all your company knowledge together.

Legal-specific tools are great, but they can create another information silo. eesel AI tackles a wider problem by learning from your old support tickets, help docs, and internal wikis. The result? It gives instant, correct answers to support agents, IT folks, and anyone else who's tired of hunting for information.

What makes it different?

• You can set it up yourself, today. Forget scheduling sales calls or waiting for a demo. You can get eesel AI up and running on your own in a few minutes. That's a massive departure from the months-long setup common with a lot of legal tech.

• It connects all your knowledge. It pulls information from your help desks, chat apps, and wikis, so you finally have one place to find everything. No more departmental silos.

• You can test it safely. Before unleashing it on your customers, you can run a simulation on thousands of your past support tickets. This lets you see exactly how it will perform and build confidence in the AI from the get-go.

Pricing:

eesel AI has straightforward pricing with no weird usage fees, so you know exactly what you'll pay each month.

• Team Plan: $239/month (billed annually) for 1,000 AI interactions and 3 bots.

• Business Plan: $639/month (billed annually) for 3,000 AI interactions, unlimited bots, and extras like training on past tickets.

• Custom Plan: For when you need unlimited interactions and other enterprise features.

2. Ironclad

Ironclad is what you'd call a full-blown Contract Lifecycle Management (CLM) platform. It's not just a tool for reviewing contracts; it's designed to handle the whole shebang, from drafting and negotiation all the way to signing and storing.

It’s a popular pick for big companies that need one system to rule all their contracts. The AI isn't just an add-on; it's woven into every step, helping pull out key data and speed up reviews within a much bigger workflow.

• The good: It has some seriously powerful automation, connects with just about everything, and gives you one central place to see all your contracts.

• The not-so-good: Getting this thing set up is a major project that takes a lot of time and people. It's way more than most small teams need, and the price tag definitely shows it's built for the enterprise crowd.

• Pricing: Ironclad keeps its pricing under wraps. You'll have to book a demo and get a custom quote for your company.

3. Spellbook

Spellbook has one job: to make contract drafting faster. It’s a clever add-in that works right inside Microsoft Word, using GPT-4 to suggest language, point out missing terms, and help you fly through redlines.

People seem to love how quick it is and how well it turns a blank document into a respectable first draft in just a few minutes.

Reddit

If you're a lawyer who spends all day in Word, this tool feels like a natural co-pilot. People seem to love how quick it is and how well it turns a blank document into a respectable first draft in just a few minutes.

• The good: It works inside the program you already use, it's pretty easy to learn, and there's a free trial. The pricing is also a bit clearer than some of its competitors.

• The not-so-good: It’s really just for drafting. Don't expect it to manage your contracts like Ironclad or handle massive due diligence projects like Luminance.

• Pricing: Spellbook doesn't post its full pricing online, so you'll need to talk to their sales team for an exact number. From what I've seen, plans seem to start around $589 per user, per month if you pay for the year upfront.

4. LegalOn

LegalOn's big selling point is its huge library of ready-to-go legal playbooks, all checked by real lawyers. This means you can start using it on day one without having to spend weeks training an AI model.

This is a fantastic option if your team mainly works with standard contracts like NDAs, MSAs, or vendor agreements and needs accurate reviews immediately. For these common documents, it's one of the quickest ways to get up and running.

• The good: You get value right away because there's no training period. It's also known for being very accurate for the contracts it's designed for.

• The not-so-good: The catch is that it's not as flexible for unique or heavily customized agreements. If your contracts don't fit its pre-built molds, you might struggle.

• Pricing: LegalOn does custom pricing. Based on what people are saying, small teams can expect to pay somewhere between $3,000 and $8,000 per year.

5. Harvey

Harvey is the big gun. It's backed by serious cash and used by some of the fanciest law firms on the planet. This tool isn't just for contracts; it's a general-purpose legal AI built for heavy-duty tasks like legal research, deep analysis, and writing complex memos.

Think of Harvey as the absolute top of the pyramid. It uses custom-trained AI models that can learn a firm's specific style and expertise.

• The good: It's insanely powerful and can be molded to fit almost any kind of specialized legal work.

• The not-so-good: It's exclusive and has a price tag that will make your eyes water. For most in-house teams, it's like using a sledgehammer to crack a nut. The setup is also a huge, hands-on process.

• Pricing: Harvey doesn't advertise its prices, but let's just say it's for big spenders. Word on the street is that it can start at $30,000 a month, maybe even more.

6. ContractPodAI

ContractPodAI is in the same camp as Ironclad, offering a complete CLM platform to manage contracts from creation to expiration. They have a GenAI assistant named "Leah" that's designed for legal work and can use different language models to do its analysis.

It's a dependable option for larger businesses that need one system to handle all their contracts and want a capable AI engine to help out.

• The good: It's tailored for legal teams, gives you choices on the AI models it uses, and is built to handle a high volume of contracts.

• The not-so-good: Just like other big CLM systems, it's really geared toward medium and large companies. The setup process can also be pretty involved.

• Pricing: You won't find pricing on their website. You have to get in touch with their sales team for a demo and a custom quote.

How to choose the right Luminance AI alternative

Feeling a bit lost in all the options? I don't blame you. Here are a few things to keep in mind to find the right tool for you.

• Figure out your real problem. Are you just trying to fix a legal review bottleneck? Or is your bigger issue that information is scattered and hard to find across the whole company? A niche tool like Luminance is fine for legal, but something like eesel AI is built to solve that bigger problem for everyone.

• How quickly do you need a win? If you don't have the time or patience for a months-long implementation project, focus on tools you can sign up for and start using yourself, right away.

• Don't accept mystery pricing. Avoid tools with complicated or hidden pricing that could lead to a nasty surprise on your bill. Look for flat, predictable fees so you know what you're getting into.

• Think bigger than just one team. The most valuable AI tools are often the ones that help multiple departments. Look for something that can help out your legal, support, IT, and HR teams all at once.

Final thoughts: It’s not just about legal anymore

There are some great Luminance AI alternatives out there if you're focused squarely on legal work. But the real power of this technology comes from using it to connect and automate your whole company.

Your legal team is drowning in contracts, sure. But your support team is drowning in tickets, and every employee is tired of digging through a messy wiki to find a simple answer. It's all the same problem: information is trapped, and finding it is a manual, frustrating process.

If you're looking for an AI tool that can help your support and internal teams, without the pain of a long and expensive setup, then eesel AI is probably what you're looking for. It’s a simple, fast, and affordable way to finally put all your company's knowledge to work.

Ready to automate more than just contracts? You can get started with eesel AI in just a few minutes.
