AI legal workflows inside Microsoft 365 — Lito AI agent, Kira contract review, and document automation used by 71% of the Fortune 100, with AI included at no extra charge.

Litera Review: The Legal AI Platform That Embedded Its AI Agent Into Core Products at No Extra Cost — and Saw 10x User Growth

Legal AI adoption has faced a persistent barrier — most tools charge separately for AI features, creating a two-tier system where firms that can afford the premium upgrade get AI capability and firms on standard contracts do not. Litera made a deliberate strategic decision in October 2025: embed Lito, its AI legal agent, into all core drafting products at no additional charge. The result was a 10x increase in monthly active cloud drafting users within months, with 26,000 plus AI document summaries generated in November 2025 alone. In 2026, Litera is the only major legal technology platform that has combined AI drafting, AI contract review through Kira, document comparison, and workflow automation in a single Microsoft 365-integrated platform — used by 71% of the Fortune 100, Am Law 100 and 200 firms, and government agencies across 700,000 plus licensed users globally.

Quick Summary

Litera is a global legal technology platform founded in 1995 — combining Litera One for Microsoft 365-integrated legal drafting and workflow, Lito AI legal agent embedded at no extra cost, Kira AI contract review platform, document comparison, metadata cleaning, deal management, due diligence, and knowledge management, across 700,000 plus licensed users at 15,000 plus firms including 71% of the Fortune 100, with module pricing from approximately $90 to $1,900 per year.

Is it worth using? Yes for law firms and corporate legal departments that use Microsoft 365 and want a unified legal AI platform where drafting, review, comparison, and workflow automation share the same AI layer — particularly the only major platform embedding its AI agent in core products without an additional cost layer.
Who should use it? Partners, associates, and legal technology leaders at Am Law 100 and 200 firms, corporate legal departments, and mid-size law firms who want enterprise-grade legal AI tightly integrated with their existing Microsoft Word, Outlook, and Teams workflows.
Who should avoid it? Solo practitioners and very small firms whose budget and workflow complexity do not warrant Litera’s full platform investment — simpler and more accessible AI legal tools like Spellbook or Harvey AI serve this segment better.

Verdict Summary

Best for

Law firms on Microsoft 365 who want legal AI that runs inside Word, Outlook, Teams, and web without requiring lawyers to switch interfaces — Litera One’s Microsoft 365 integration is its defining advantage over platforms that require a separate application
Corporate legal departments doing high-volume contract review who want Kira’s AI extraction working alongside Litera’s drafting tools in one ecosystem rather than running two separate legal AI platforms
Firms that want AI without an additional cost premium — Lito’s inclusion at no extra charge in all Draft plans is the most aggressive AI democratisation move in enterprise legaltech in 2025/2026

Not for

Solo practitioners and very small firms where Litera’s complexity and pricing are disproportionate to the team size and workflow
Firms whose primary need is AI contract review accuracy benchmarking — LegalOn has published third-party 2026 benchmark results; Litera has not published comparable head-to-head accuracy data
Teams who primarily use Google Workspace — Litera is Microsoft-first and the full platform value requires Microsoft 365 for the deepest integration

Rating
⭐⭐⭐⭐ 4.3 / 5

What Is Litera?

Litera is a legal technology company founded in 1995 — headquartered in Chicago with offices in London — that has grown through strategic acquisitions to become one of the most comprehensive legal workflow platforms available. The company’s acquisitions include Kira (AI contract review), Workshare (document comparison), Business Integrity (metadata cleaning), and others — creating a platform that covers the full legal document lifecycle from drafting through review, comparison, and archival.

In 2026, Litera’s strategic positioning centres on being the platform that best unifies the practice and business of law — not as a standalone AI tool but as the integration layer that connects lawyers’ daily workflows in Microsoft Word, Outlook, and Teams with AI that understands legal content, legal conventions, and legal knowledge management.

Lito — Litera’s AI legal agent running on the best available large language models including GPT-5.6 Sol and GPT-5.6 Terra — is embedded throughout the Litera platform, available to existing Draft Base, Pro, and Advanced customers at no additional charge.

How Litera Works

Work inside Microsoft 365. Litera One runs natively inside Microsoft Word, Outlook, Teams, web, and mobile — lawyers access all Litera capabilities without leaving their daily Microsoft environment. No new application interface to learn.
Draft with AI assistance. Litera’s drafting tools combine clause libraries, document assembly, template management, and Lito AI — which generates AI summaries, recommends next steps in drafting, flags potential issues, and navigates complex document hierarchies with firm knowledge context.
Review contracts with Kira. Kira’s AI contract review extracts key terms, identifies risky provisions, and highlights non-standard language across uploaded contracts — supporting due diligence, M&A, commercial contract review, and compliance workflows.
Compare documents with AI. Litera Compare detects changes between document versions — integrated with iManage, NetDocuments, and SharePoint — providing lawyers with accurate redlines without switching document management systems.
Clean document metadata. Litera Clean removes metadata, hidden text, and tracking information from documents before sharing externally — a critical workflow step in legal document handling that Litera has provided since 1995.
Manage matters and deals. Litera’s matter management and deal management tools provide budget oversight, out-of-scope work notifications, and transaction management — converting manual deal coordination into structured workflows.

Real-World Use Cases

No-cost AI adoption at scale: A 200-lawyer firm already on Litera Draft receives Lito as part of their existing subscription at no added cost. Within three months, 85% of lawyers are using Lito for document summaries, drafting assistance, and knowledge queries — adoption that would not have occurred if Lito had been priced as a premium add-on requiring separate budget approval.
M&A due diligence acceleration: A corporate team uses Kira to review 500 contracts in a seller’s data room — Kira extracts key terms, identifies change of control provisions, and flags non-standard indemnification clauses across all 500 agreements simultaneously. The extraction work that previously required a junior associate team working two weeks completes in hours.
Document comparison workflow: A partner receives a counterparty redline on a 60-page agreement. Litera Compare opens directly from within Word through the Litera One integration — generating a tracked-changes comparison against the firm’s last clean version without opening a separate application or uploading files to an external tool.
Lito knowledge query: An associate working on a complex transaction needs to understand how a specific clause type has been handled in the firm’s previous comparable deals. They ask Lito directly in Word — Lito queries the firm’s knowledge base, surfaces relevant precedent language and handling approaches, and surfaces the specific clause examples from past matters without the associate manually searching document management.

Pros and Cons

Pros	Cons
Lito AI agent embedded at no extra cost — the most significant AI democratisation move in enterprise legaltech, driving 10x user growth in months	Complex platform with many modules — understanding which combination to purchase for a specific firm’s needs requires dedicated evaluation and potentially implementation support
Microsoft 365 integration depth — lawyers work inside Word, Outlook, and Teams without a new interface, the highest-adoption legal AI approach available	Module-level pricing from $90 to $1,900 per year per module adds up — full platform deployment requires significant investment when all relevant modules are combined
Kira AI contract review processing millions of files is among the most validated AI contract review capabilities in the market	No published head-to-head accuracy benchmark data comparable to LegalOn’s 2026 Contract Review Benchmark — buyers evaluating on accuracy need to run their own pilots
71% Fortune 100 adoption and 700,000 plus licensed users — enterprise validation at a scale that few legal technology platforms match	Google Workspace firms do not get the same integration depth — Litera is Microsoft-first and the full value requires Microsoft 365
10x growth in cloud drafting users post-AI democratisation — the usage data validates that no-cost AI access works as an adoption strategy	Acquisitive growth model means platform integration quality varies across the acquired product suite — Lito and Litera One are tightest; older acquired modules may feel less unified

For any legal technology leader whose firm wants AI workflows inside the Microsoft tools lawyers already use, without a separate AI budget line and without a new application to learn, Litera provides the unified platform that makes legal AI genuinely accessible at scale.
