Walk the exhibition floor at any Australian legal tech conference and you will hear the same pitch at every second stand: a purpose-built tool for one slice of legal work. Contract review here, e-discovery there, matter intake at the next table. Each one is competent at its single job, each one is priced per user per month, and each one adds another login, another data silo and another line to the software budget.
General-purpose AI agents change that maths. Claude, given secure access to a firm's documents and systems, can review a contract on Monday, summarise a lease on Tuesday and triage the intake inbox on Wednesday, with no new platform for any of it. This guide looks at where legal automation tools still earn their keep, and where a general agent now does the job better and cheaper for Australian firms.
What point tools still do well
Dedicated legal SaaS is strongest where the work is structured, high-volume and regulated. A litigation e-discovery platform that can ingest two million documents, deduplicate them and hold a defensible chain of custody is not something you rebuild with a general agent. The same goes for software with compliance obligations baked in. Trust accounting products encode the Legal Profession Uniform Law rules for NSW and Victoria, produce the reports your external examiner expects, and carry vendor accountability if the calculations are wrong.
Court and registry lodgement: tools with direct integrations into state e-filing systems save real time and reduce rejection rates.
Trust accounting: state-based compliance rules, audit trails and examiner-ready reporting belong in certified software.
Litigation-scale e-discovery: document volumes in the millions need purpose-built processing and defensibility.
Practice management systems of record: your matter database, time capture and billing engine should stay put.
Where a general agent beats the point tool
Most legal work is not high-volume and structured. It is a long tail of one-off tasks: précis a planning decision for a client email, cross-check a costs disclosure against the file, compare a supplier's amended terms against the version signed in 2023. No SaaS product exists for most of these because no single task has enough buyers to justify one. A general agent handles the whole tail.
Cross-system work. A point tool stops at the edge of its own database. Claude can read the email, draft the advice, update the matter spreadsheet and log the file note in one pass.
Judgment tasks. Template diffing flags what changed; an agent can also flag why a clause is unusual for this counterparty, this industry or this state.
The niche work no vendor serves. Regulatory summaries, tender responses, precedent bank tidy-ups and internal knowledge questions all fall outside every point tool's box.
Cost structure. One subscription covers every task type, instead of a per-seat fee for each category of work.
Portability. Prompts, playbooks and checklists are plain documents you own. Cancelling a point tool usually means losing the workflow along with the licence.
The pattern is consistent across the firms we talk to: the point tool wins inside its box, and the general agent wins everywhere between the boxes. The surprise is how much of a legal practice's week happens between the boxes.
The cost picture in Australian dollars
Mid-tier legal point tools typically land between $120 and $250 per user per month. A five-lawyer Sydney practice running a contract review tool, a document automation platform and an AI research add-on can pass $45,000 a year in subscriptions before anyone opens a matter. A Claude Team or Max plan for the same five people costs roughly $4,500 to $9,000 a year. Even after adding a proper setup engagement, secure document access and staff training, firms that consolidate two or three point tools onto a general agent commonly cut their AI and automation spend by more than half while widening what it covers.
The honest caveat: a general agent needs configuration to be useful. Out of the box it does not know your precedents, your house style or your risk positions. Budget for a short setup project, not just licences, and compare total first-year cost rather than sticker price.
What this looks like in practice
A suburban firm we spoke with ran the comparison on its commercial lease work. The point tool reviewed leases against a fixed checklist and produced a report. Claude, set up with the firm's own precedent bank and instructions, produced the same clause-by-clause review, then drafted the client letter, flagged two Privacy Act considerations in the data-handling clause, and filed the summary into the matter folder. Same review time, three extra steps completed, and the work product stayed in the firm's own systems, which matters for legal professional privilege and for the data residency questions Australian clients increasingly ask.
None of this removes the lawyer. Every output above went to a solicitor for review before it left the building, and professional obligations make that non-negotiable. The gain is that the solicitor starts from a completed draft instead of a blank page.
How to decide, tool by tool
Rather than an all-or-nothing swap, audit each subscription on its own merits:
Keep it if the tool performs a regulated function, holds a system-of-record role, or integrates directly with courts and registries.
Trial against the agent if the tool is mainly a wrapper around document drafting, review or summarisation. Run both on the same ten matters for 30 days and compare outputs.
Cancel-candidate if the tool is used less than weekly. The long tail is exactly where a general agent is strongest.
Most Australian firms that run this audit end up with a smaller, cheaper stack: practice management and trust accounting stay, one or two review tools go, and a general agent picks up the freed budget plus a much wider brief. If you want a second pair of eyes across your legal software stack before renewal season, book a no-obligation chat with us and we will map which tools are safe to keep and which the agent can replace.
