The Cost Problem in Legal AI
One of the biggest barriers for small and medium businesses using AI for legal work is cost. AI tools that review contracts, draft clauses, and check compliance are powerful, but they burn through tokens — and that means a growing bill. For a business that sends a handful of contracts through an AI legal tool each month, the costs can quickly add up to more than hiring a solicitor for a quick review.
A company called Syntheia has found a way around this problem. Their approach is not about using a cheaper AI model — it is about being smarter with how the contract is processed before the AI ever sees it.
How It Works
The core insight is simple. When you feed a large contract — say, a commercial lease or a supplier agreement — into an AI model, you pay for every word the model processes. Most AI tools treat the entire document as one block, processing every clause, every definition, every schedule in one go. That is expensive, because large language models charge by the token (roughly, by the word).
Syntheia’s innovation is to “slice” the contract differently before applying AI. Instead of processing the whole document at once, they break it into meaningful sections, identify which parts actually need AI analysis, and only process those. Redundant clauses, standard terms that never change, and boilerplate language are handled by traditional rule-based systems that cost almost nothing to run. The AI is only called in where human-level judgment is actually needed.
The result is a dramatic reduction in token usage — and therefore in cost. Early reports suggest the approach cuts AI processing costs by a significant margin, making automated contract review viable for businesses that would previously have been priced out.
Real-World Example
Imagine you run a small construction company in Kildare. You take on a subcontract for a larger developer. The contract is fifty pages long, full of legal jargon about liability caps, indemnity clauses, and dispute resolution. You could spend €1,500 on a solicitor to review it, or you could run it through an AI tool that flags the five clauses that need attention — and then pay the solicitor €300 to focus only on those parts. That is the kind of saving the new approach enables.
And it is not just about money. It is about speed. In a competitive tender, being able to review and sign a contract in hours rather than days can be the difference between winning the job and losing it to someone else.
Why Irish Businesses Should Care
Irish businesses deal with contracts constantly. Commercial leases for shopfronts in Galway and Cork. Supplier agreements for the hospitality sector. Service contracts for IT and professional services. Employment contracts for growing teams. For most small and medium businesses, getting a solicitor to review each contract can cost anywhere from a few hundred to several thousand euro, depending on complexity.
AI tools that can handle the initial review — flagging unusual clauses, checking compliance with Irish and EU law, highlighting risks — could save significant money. But only if the AI costs less than the solicitor. That is where the token-saving approach matters. By reducing the processing cost per contract, tools like Syntheia make legal AI accessible to businesses that are not multinationals.
There is also a time benefit. A contract that would take a solicitor a day to review can be analysed by AI in minutes. For a busy business owner, that speed can make the difference between signing a deal this week or next month.
What to Watch For
This approach to legal AI is still emerging. The technology works best for standard commercial contracts — leases, supply agreements, NDAs, employment terms. Highly specialised or unusual contracts still need a human solicitor. And even with efficient AI processing, legal advice from a qualified professional remains essential for important decisions.
But the trend is clear. Legal AI is getting cheaper, faster, and more practical for everyday business use. Irish businesses that keep an eye on this space will be well placed to benefit.
