How legal teams actually use document automation in 2026
The surprise of 2026 is that the rules-based tools did not die. Two years into generative drafting, a vendor whose AI drafting product was by its own account thriving, Gavel, shipped a major release of its questionnaire-and-logic engine and said why in one line: "When the document's structure is known, rules-based automation is faster, safer, and more accurate." Six months later Relativity, the e-discovery company, bought it. Josef, which sells to in-house teams, put its new AI not in the template but in front of it, reading the messy email that arrives before the template runs.
That is the shape of the good products now. A will, a lease, a court form or a regulatory dossier has a structure everyone knows; the part that has to be understood is the instruction that comes in and the exceptions that come out. The tools below split on where they put the model, and this guide sorts them that way: rules-based assembly, which fills a known structure from answers; generative drafting, which writes and reviews language against precedent; and bundles that do some of both inside practice-management software. A short section covers the separate world of regulatory submissions, where "document automation" means a submission dossier for a medicines regulator.
Adoption is no longer the question. Clio's 2025 Legal Trends report found 79 per cent of firms using AI in some form, and Thomson Reuters' 2026 survey of professionals has 74 per cent using it several times a week, a third of them on tools their organisation never approved. The ten tools here come from the 18 in our document automation directory. Nobody paid to be listed, there are no affiliate links, and where a price is not published the table says "quote" rather than inventing one.

The tools in detail
1. Gavel
Gavel, formerly Documate, is the rare vendor that does both halves and prints its prices. The core is no-code automation of Word and PDF templates driven by questionnaires that a client can fill in online, with a Workflows release in December 2025 adding nested conditions and calculations. Gavel Exec, launched in 2025 and extended to the web in April 2026, is the AI side: contract review and drafting in Word, and batch analysis that reads a stack of contracts and returns a table of terms. Lite is $83 a month, Standard $165, Pro $290, Scale from $417 on annual billing, with a seven-day trial. Relativity announced its acquisition of the company in June 2026 and says it will run independently. Visit Gavel.
2. HotDocs (Mitratech)
HotDocs is the template engine everyone else was measured against for three decades, and it still turns a firm's most-used documents into logic-driven templates that fill from existing data. Mitratech bought it in 2024 and now positions HotDocs Advance with AI-assisted authoring, meaning the model helps build the template rather than write the document. The company claims document creation time cut by up to 90 per cent, a vendor figure, and more than a million end users across legal, insurance and government. Pricing by quote. Visit HotDocs.
3. Knackly
Knackly is pure rules-based automation for the practices that generate the same documents all day: estate planning, family law, litigation, loan work. Guided interviews, client questionnaires, PDF automation, no generative AI on the feature list at all. The pricing is unusually honest about where the work is: Starter at $250 a month for four users, a $500 tier where Knackly automates your first document for you, and a $1,000 tier where they do all of it. It claims 80 per cent of drafting time saved, which is the vendor's number. Visit Knackly.
4. PatternBuilder MAX (NetDocuments)
NetDocuments bought Afterpattern in 2021 and made it native to its document management system, which is the point: the automation runs where the documents already live, with the firm's own permissions. MAX adds generative "Studio Apps" for summarising, drafting, extracting terms and checking a contract against a playbook, and Smart Answers, rolling out since March 2026, answers questions across a firm's whole repository with citations. There is an MCP connector for enterprise customers and direct integration with ChatGPT and Claude. More than 13,000 users at last published count; pricing by quote. Visit NetDocuments.
5. Legito
Legito is document automation for back-office teams beyond legal, procurement, HR and finance among them, with contract lifecycle and workflow tools wrapped around it. Its Kedy AI extracts metadata, converts an existing Word document into an automated template and drafts from an incoming email into the right template. The line that matters to a compliance officer is on its AI page: the data stays on Legito's own servers and no third-party service processes it. Quote pricing, with a 30-day trial that needs no card. Visit Legito.
6. Josef
Josef sells to legal departments rather than law firms, and its April 2026 release is the clearest statement of the 2026 design: a Rapid Ingestion Engine that reads a term sheet or a rambling email and turns it into structured inputs for a no-code workflow. Its founder's framing, that "AI should read the mess that arrives before the template runs", could be the caption for this whole guide. Josef Q, its earlier product, turns internal policies into a question-and-answer tool with a human in the loop. Named customers include adidas, L'Oréal and Bumble; L'Oréal says a contract that took over an hour now takes twenty minutes. Quote only. Visit Josef.
7. Clio Draft
Clio Draft, the product that used to be Lawyaw, is document automation for the solo and small US practice already running on Clio: AI turns your existing Word documents into reusable templates, a library of court forms covers all 50 states plus immigration forms, and questionnaires, document sets and e-signature sit on top. Since Clio's October 2025 relaunch, Draft AI produces first drafts inside the same platform. It starts from $49 a month, the same entry price as Clio's practice-management Starter plan. Visit Clio Draft.
8. Smokeball
Smokeball bundles document automation into practice management, with an automated forms library and, since July 2026, a next-generation Archie assistant that reasons through multi-step tasks, redlines in tracked changes and runs playbook reviews from add-ins in Word and Outlook. The company says Archie has taken 2.5 million prompts and has 20,000 daily users. Document automation is included in its higher tiers, Archie is an add-on, and pricing depends on users, tier and term, so it is quoted. Visit Smokeball.
9. DraftWise
DraftWise is the pure generative entry, and its idea is that the best precedent for your next agreement is the last hundred you signed. It reads a firm's own deal history and drafts, reviews and negotiates in Word against it; a Playbook Studio arrived in February 2026 and a Legal Ontology in August, which maps the judgement lawyers apply across amendments and side letters so it can be reused. Orrick and Gunderson Dettmer are named users. Pricing by quote, aimed at large transactional practices. Visit DraftWise.
10. Contract Express and CoCounsel Drafting (Thomson Reuters)
Thomson Reuters has both generations under one roof. Contract Express is the questionnaire-driven template product, with generative AI added in 2024 to build the template itself; the company claims a three-page contract that takes 30 to 60 minutes to automate by hand takes about two minutes, its own number. CoCounsel Drafting, part of the August 2026 CoCounsel Legal release, drafts and edits in Word from natural-language instructions with Practical Law content behind it. The company says a million professionals in 107 countries use CoCounsel. Quote only. Visit Contract Express.
Also in the directory: Spellbook, the Word-native contract assistant we cover in the contract review guide, and Filevine, whose case-management platform assembles documents from case data and generates demand letters and immigration forms with AI.
Regulatory documents: a different job with the same name
"AI software for regulatory documents" is one of the queries that brings people here, and it mostly means something other than legal templates: the submissions that medicines, devices and listed companies file with their regulators. Veeva's Vault RIM is the platform of record for pharmaceutical submissions, and its Falcon agentic layer, announced in May 2026, promises agent-drafted regulatory documents for early adopters in November. Certara's CoAuthor drafts clinical and regulatory sections in Word from templates and joined Veeva's partner programme in 2025; the company claims first drafts 30 per cent faster, its own figure. Freyr's freya fusion covers dossiers, labelling and health-authority questions and cites more than 200,000 submissions processed. Yseop, which automates clinical study reports and patient narratives, is one of the few in this segment with a printed price: $600,000 for a 12-month contract on the AWS Marketplace. On the financial side, Workiva added AI agents for SEC-style reporting in July 2026 and serves most of the Fortune 1000.
The regulator's own position is worth knowing. The US Food and Drug Administration's January 2025 draft guidance proposes a risk-based framework for AI used to support regulatory decisions, notes that its drug centre saw more than 500 submissions with AI components between 2016 and 2023, and remains a draft with non-binding recommendations. The regulatory compliance page in the directory lists the tools in this segment, and our risk management software guide covers the neighbouring category.
How to choose
Sort your documents before you sort the vendors. Which of them have a structure you could draw on a whiteboard? Those go to rules: Knackly, HotDocs, Gavel's core, Clio Draft's form library. Which of them arrive as a mess and leave as an exception? Those are where a model earns its keep: Josef at intake, DraftWise or CoCounsel against precedent, Gavel Exec for a stack of contracts. Most practices have both kinds, which is the case for the bundles that do both inside the software you already run.
Then decide where the check sits, because the sanctions record is now specific. In May 2025 a federal court in California ordered two firms to pay $31,100 after a brief built from an AI-generated outline cited authorities that "do not exist at all"; in March 2026 an appeals court fined two lawyers $15,000 each and put the rule in one sentence, that no brief should contain a citation the lawyer has not personally read and verified. A template cannot invent a case. A drafting model can. None of that argues against the model. It argues for knowing which paragraphs came from which.
Own the templates
Rules-based templates are an asset you keep if you leave. Ask how you export them, and whether the AI-built ones are in a format you can read.
Ask where the text goes
Legito keeps AI on its own servers; others send it to a model provider. For client documents, the data terms are part of the product.
Re-run last month
Take twenty finished documents and produce them again through the candidate tool. The differences, and who caught them, are the only benchmark that fits your practice.
There is a tension in this market that does not resolve into a recommendation: the tools that save the most time are the ones that write, and the tools you can trust without reading are the ones that only fill. Every vendor above is working on the seam between those two, and the ones that name it plainly, as Gavel and Josef have, are easier to buy from. For the wider category, the legal and compliance directory and our AI tools for lawyers guide cover research and practice tools; for the non-legal version of the same job, the document tools and PDF tools pages list the general-purpose options, and comparing two PDF versions with AI is the how-to for checking what changed.
Frequently asked questions
For a US practice already on Clio, Clio Draft from $49 a month is the obvious start. For a firm that wants client-facing questionnaires and AI review with prices in the open, Gavel at $83 to $290 a month. For high-volume estate or family work with no appetite for generative AI, Knackly at $250 a month, or $500 if you want them to build the first template. Smokeball suits a firm that wants everything in one system.
Document automation fills a template whose structure is fixed from answers to questions; it cannot produce anything the template author did not allow. AI drafting writes or reviews language from a model, usually against your precedent or a playbook, and can produce text nobody wrote before. The first is safer for known documents; the second handles the unknown ones. Most 2026 products do both, and the useful question is which paragraph came from which.
Published prices run from $49 a month (Clio Draft) through $83 to $417 (Gavel) to $250 to $1,000 (Knackly). Enterprise tools, HotDocs, PatternBuilder, Legito, Josef, DraftWise and the Thomson Reuters products among them, are quoted per seat on annual contracts. In regulatory writing the numbers are of a different order: one vendor lists $600,000 for a twelve-month contract.
Yes, and it is a separate market from legal templates. Veeva Vault RIM, Certara CoAuthor, Freyr's freya fusion and Yseop cover pharmaceutical and clinical submissions; Workiva covers financial and securities reporting. The US drug regulator's 2025 draft guidance sets out a risk-based framework for AI used in submissions and is still non-binding. See the regulatory compliance tools page.
Safe enough that most firms now use it, and risky enough that courts have sanctioned lawyers in 2025 and 2026 for filing AI-generated citations nobody checked. The tools that ground drafting in your own precedent or in a verified library reduce that risk; none removes the duty to read what you file. Where client data goes, and whether it trains anyone's model, is the other question to settle before a real matter touches the tool.
