Litera One boosts workflows at US law firm with AI

Litera has shared new customer results from Hand Arendall Harrison Sale after the US law firm rolled out Litera One as part of a wider technology modernisation programme. Litera pointed to immediate returns and rapid user adoption.

Hand Arendall Harrison Sale is one of the larger firms in the south-eastern United States, with more than 85 lawyers across Alabama and Florida. The firm deployed Litera One across its document workflows in Microsoft 365, with access also available via web and mobile.

The deployment focused on drafting, document comparison and collaboration. By embedding tools in applications lawyers use every day, including Microsoft Word and Outlook, the approach reduced context switching, Litera said.

Document comparison was a key area of change. Some of the firm's most experienced users had faced friction with prior comparison tools, according to Litera. After the rollout, the firm recorded zero complaints and one Help Desk call.

Deborah Savadra, application support specialist and trainer at Hand Arendall Harrison Sale, said the firm saw a change in day-to-day work after the integration went live.

"Litera One just runs circles around Word, and the Outlook integration is a game-changer," said Savadra. "Having Litera One directly within Word and Outlook makes the user experience seamless, and the iManage integration removes friction so that the DMS remains our source of truth for client matter documents."

Platform approach

Litera One groups drafting and review tools in a single interface across Word, Outlook, web and mobile, according to the company. It also integrates with document management systems such as iManage and NetDocuments. Litera positioned this as a way for firms to maintain document governance while changing the authoring and review experience for lawyers.

The announcement also pointed to a broader pattern Litera says it is seeing across the legal sector: firms are moving away from separate tools for editing, comparing and collaboration, and towards unified workflows inside the Microsoft 365 applications lawyers already use.

The shift reflects a push for faster rollouts and fewer disruptions to established practices. In many firms, document production sits at the centre of fee-earning work. Any change to templates, comparison features, filing processes or email integration can affect productivity and user acceptance.

Hand Arendall Harrison Sale adopted Litera One as part of a broader upgrade to its technology environment, Litera said. Contract terms and deployment size were not disclosed. Litera did not provide a quantified return figure, but described the results as immediate and linked them to low support demand after rollout.

AI agent

Litera also highlighted Lito, its AI legal agent. It described Lito as using firm knowledge and context to provide guidance during drafting, review and knowledge management workflows.

Lito is positioned as a layer across the Litera One platform rather than a standalone product. Litera said it can interpret intent and recommend next steps in document-centric work. It also said Lito received a 2025 AI Core Technology Award from TMCnet.

Joey Benedek, VP of Product at Litera, said customer demand is being driven by pressure on legal teams to increase productivity without increasing headcount.

"Law firms are under more pressure than ever to do more with less, and experiences built on the Litera One platform delivers on that promise from day one," Benedek said. "What we're seeing with firms like Hand Arendall Harrison Sale isn't just faster document workflows. It's a fundamental shift in how lawyers work - with less friction, more confidence, and more time for the work that matters. When you combine that with the intelligence of Lito, our AI orchestration layer, you're not just modernizing a process. You're transforming a firm."

The comments come as vendors across the legal technology sector invest in generative AI features inside familiar productivity tools. Many firms already rely on Microsoft 365 as the base layer for email and document creation, making Word and Outlook key integration points for suppliers seeking adoption and usage at scale.

Litera is presenting customer stories and product demonstrations at Legalweek in New York, where it is showing Litera One's drafting and comparison functions alongside Lito's agent-based features.
