Top 10 AI Tools Every Legal Professional in Viet Nam Should Know in 2025

AI matters for legal professionals in Viet Nam in 2025 because it's no longer hypothetical - global research shows rising use and mounting regulatory attention, and practical gains are tangible: generative tools can free up roughly 240 hours per lawyer per year, accelerate document review and eDiscovery, and turn repetitive work into strategic advice for clients who increasingly expect tech‑savvy counsel.

Local teams should watch global trends like Stanford HAI's 2025 AI Index for policy signals and begin retraining junior lawyers into oversight roles that validate AI outputs and manage client risk - practical moves outlined in our Vietnam guide.

Smart adoption in VN means pairing productivity wins with tight privacy and ethics controls, targeted training, and clear firm policies so AI boosts client value without compromising confidentiality or professional standards.

“The role of a good lawyer is as a ‘trusted advisor,' not as a producer of documents ... breadth of experience is where a lawyer's true value lies and that will remain valuable.” - Attorney survey respondent, 2024 Future of Professionals Report

Methodology focused on practical, Vietnam‑relevant criteria: prioritize enterprise‑grade security (SOC 2, encryption, clear data‑processing terms and zero‑data‑retention), measurable ROI and usability so tools actually save billable time, fit with local workflows and cloud choices (Microsoft 365/Azure integrations are common in VN firms), plus vendor transparency, implementation complexity and human‑in‑the‑loop controls for high‑stakes outputs.

Shortlists began with checklist-driven vendor reviews (the “five essential” security and trust pillars), hands‑on trials to test onboarding and language/workflow fit, and procurement questions that map to compliance and data residency needs; teams then scored candidates on integration, matter management vs.

point‑tool fit, and vendor support. This approach echoes practical buyer guidance on usability and security and Microsoft's Zero Trust‑style AI risk controls, so recommendations are defensible, auditable and tuned to Vietnamese legal practice.

One reminder: 80% of leaders name data leakage as a top concern, so security filters weren't optional - they were the gatekeeper.

Criteria	Why it matters for VN legal teams
Security & Compliance	Protects client confidentiality and meets cross‑border rules
Usability & ROI	Ensures adoption and real time savings for busy lawyers
Integration & Scalability	Fits existing Microsoft/Azure ecosystems and grows with firm
Vendor Transparency	Auditability, DPAs and clear data‑use terms

“A task that would previously have taken an hour was completed in five minutes. Something that would've taken us a couple of weeks to do, now gets back to the business‑side in a day or two. That's huge.” - Jarret Coleman, General Counsel

LEGALFLY - framed as the secure, in‑house approach Vietnamese legal teams should favour - means treating contract review and compliance as a tenant‑bound, auditable AI workflow rather than an open web experiment: choose solutions that ground outputs in your firm's Microsoft 365 data, keep prompts and responses inside your tenant, and enforce strict access controls so confidential clauses don't leak across teams.

Practical steps include testing each Copilot‑style surface (Word, Teams, Outlook) to see what artifacts are produced, insisting on vendor transparency about data use, and aligning rollout with staff retraining so junior lawyers move into oversight roles that validate AI drafts and preserve privilege (see Microsoft's guide to AI for legal and LexisNexis's work on Protégé for examples of Microsoft‑integrated, enterprise‑grade assistants).

For Vietnam, pairing this secure architecture with localized prompts and privacy mappings - like the mutual NDA healthcare prompt used in cross‑border deals - turns AI from a risky toy into a controlled productivity engine for compliance and review.

“LexisNexis is putting Gen AI technology to work for legal professionals in practical ways.” - Serena Wellen

CoCounsel (Thomson Reuters / Westlaw) is the professional‑grade AI assistant Vietnamese legal teams should evaluate first: it pairs Westlaw and Practical Law authority with agentic workflows and Deep Research to speed research, document analysis and drafting while keeping results verifiable and citable - think finding “the needle in the haystack among millions of pages” in minutes rather than days.

For cross‑border matters common in VN practice, features like AI Jurisdictional Surveys and Practical Law playbooks give fast, jurisdiction‑tailored starting points, and seamless Microsoft 365/DMS integration helps preserve firm‑level security and audit trails.

CoCounsel's emphasis on grounded, RAG‑style answers, the Practical Law AI Toolkit and prompting guidance make it a defensible choice where ethical duty and data risk matter; firms should pair rollout with governance and the retraining of junior lawyers into oversight roles (see our retraining guidance).

“The AI‑generated summary of results above the list of primary law authority can be extraordinarily useful for getting an overview of the issues and pointers to primary authority, but it should never be used to advise a client, write a brief or motion for a court, or otherwise be relied on without doing further research. Use it to accelerate thorough research. Don't use it as a replacement for thorough research.”

Lexis+ AI stands out as an all‑in‑one platform Vietnamese legal teams should evaluate for research, drafting and litigation analytics: its Protégé assistant and private Vault let users draft full transactional documents, run deep document analysis and even generate graphical timelines from multiple filings in moments, while Shepardize® citation checks and litigation analytics help verify authority and judge/court trends for cross‑border disputes.

Multi‑model, privacy‑by‑design architecture (Azure/AWS Bedrock plus private models), DMS connectors like iManage and SharePoint, and features such as Default Jurisdiction and an uploads grid make it practical to embed AI into existing firm workflows without losing auditability.

For firms needing defensible, citation‑backed outputs, the combination of document upload + Brief/Agreement Analysis and guided research turns piles of discovery into usable strategy - a tangible way to move lawyers from document production to client advice.

“Lexis+ is my favorite tool - it is comprehensive, easy to use, and very helpful in its layout and functionality.” - Katherine Powell, Law Clerk

Bloomberg Law's Litigation Intelligence Center brings litigation analytics and contract‑focused drafting tools that Vietnam firms should seriously evaluate for cross‑border disputes and complex civil matters: its analytics surface judge and court patterns, attorney and firm histories, dockets and verdicts, and even expert‑witness profiles so teams can build a data‑driven strategy rather than relying on intuition alone (see the Bloomberg Law Litigation Intelligence Center for details).

Practical features like the Brief Analyzer speed review by extracting cited authorities, undisputed facts and argument structure from uploaded briefs, while the Litigation Analytics dashboards let lawyers compare judges, motions and outcomes to anticipate risks and craft targeted arguments - in short, turning dozens of dockets into a judge‑specific playbook instead of wading aimlessly through PDFs (read a clear feature summary in this Bloomberg Litigation Analytics overview).

For VN practices adopting AI, pair Bloomberg's outputs with oversight workflows and the retraining of junior lawyers into validation roles so analytics accelerate strategy without compromising client confidentiality or ethical duty.

Microsoft 365 Copilot offers a practical, tenant‑first way for Vietnamese legal teams to fold AI into everyday drafting and review: it works inside Word, Outlook, Excel and Teams, uses Microsoft Graph to ground answers in the documents and mail a user already has permission to access, and even lets editors reference up to three files to improve grounding in a draft - making clause‑level checks and client‑ready summaries far faster without lifting files into unknown services.

Copilot's strengths for VN practice are familiar and tangible: draft and refine clauses in Word, get formula or data‑insight help in Excel, and turn long email threads or meeting transcripts into concise action items in Outlook and Teams - capabilities that enterprise customers report shave meaningful time from routine work (some users save 30+ minutes daily).

Pair Copilot with Purview, Restricted SharePoint Search and scoped Agents during rollout, and follow local guidance - retraining junior lawyers into oversight roles - so productivity gains don't come at the cost of client confidentiality or compliance.

Copilot surface	Practical VN legal use
Word	Draft, rewrite and generate automatic summaries grounded in tenant files
Excel	Suggest formulas, clean data and create visual insights for deal models
Outlook	Summarize email threads and extract action items
Teams	Summarize meetings and create follow‑up tasks from transcripts

ChatGPT is the Swiss‑army knife many Vietnamese legal teams will use for first drafts, Q&A, client‑friendly explanations and internal knowledge bases - but only if firms pair it with tight controls and savvy prompts.

Practical guides show how to get reliable value (role‑based prompts, playbooks and chunked workflows) while avoiding hallucinations and overdependence; treat outputs as first drafts or summaries to be verified against authoritative sources and firm playbooks (see a hands‑on primer on ChatGPT use cases and prompt tips).

For cross‑border or confidential matters, enterprise features matter: ChatGPT Enterprise supports file upload, deep research and long context windows so a 120‑page judgment plus briefs can be turned into a single issue table - useful when time is tight - while giving administrators retention controls and encryption (see a feature overview of ChatGPT Enterprise).

Start with low‑risk tasks (templates, intake scripts, client summaries), redact sensitive data or run work in a private tenant, and align rollout with staff retraining so junior lawyers move into oversight roles that validate AI outputs and manage client risk (retraining guidance for Vietnamese firms).

With disciplined prompts, review gates and enterprise protections, ChatGPT becomes a force multiplier rather than a liability.

“The good news is, as lawyers, we work in language. And generative AI is built on large language models. So we're the perfect candidates to be great prompt engineers.”

Harvey AI is a domain‑specific assistant worth testing for Vietnamese teams that handle cross‑border contracts and complex litigation: its Assistant and Knowledge features are trained to deliver grounded legal answers and citations, while the Vault offers secure project workspaces that can upload, store and analyze thousands of documents - turning large document sets into an interactive Review Table for fast due diligence and clause extraction (see Harvey's product overview).

For VN firms already invested in Microsoft, Harvey's Azure deployment and DMS integrations make it straightforward to keep work inside tenant controls and audit trails, matching the secure, tenant‑first approach recommended for local practice (read more about Harvey on Azure).

Enterprise‑grade security and domain‑specific models mean firms can embed firm playbooks and generate defensible outputs, but rollout should still start with low‑risk pilots and clear validation gates: retrain junior lawyers into oversight roles that verify AI drafts and manage privilege so productivity gains don't compromise client confidentiality or ethics (retraining guidance for VN legal teams).

“The legal industry is evolving rapidly, and AI is essential to keep pace with growing complexity. Harvey has transformed how we work - enabling us to navigate challenges with precision, tackle intricate legal issues, and focus on delivering strategic value.” - Dr. Claudia Junker, General Counsel, Deutsche Telekom AG

HyperStart CLM is a practical, tenant‑friendly contract lifecycle platform that Vietnam legal teams can evaluate when speed, security and easy integration matter: AI filters let users find contracts in under two seconds, auto‑extract metadata to prevent missed renewals, and AI‑powered redlining plus version control can shave negotiation time by as much as 75% - turning a 40‑page MSA review into a first‑cut list of ~20 critical items in under a minute.

Built to cover legal, sales, procurement and HR workflows, HyperStart connects with SharePoint, Outlook and common eSignature providers so firms using Microsoft 365 can keep work inside familiar systems, and the vendor emphasises enterprise security (ISO/SOC certifications, end‑to‑end encryption) and fast rollouts (claims of 3–7 day implementations).

Read HyperStart's product overview for feature details and see the negotiation and AI redlining capabilities on their contract negotiation page to judge fit for VN practice and compliance needs.

“An MSA from a big client sometimes goes to 40 pages. The usual time for the legal counsel to manually review it and revert would be between 4 and 6 hours. Using HyperStart, we can get a first-cut review with highlights of around 20 critical items in less than one minute.” - Om Prakash Pandey, Legal Counsel Head

Kira Systems brings machine‑learning clause extraction that Vietnamese firms should test when high‑volume M&A or cross‑border due diligence threatens to swallow junior teams: its lawyer‑trained AI “reads” contracts at scale, identifying and extracting 1,400+ clauses and data points across 40+ substantive areas, grouping amendments and producing exportable summaries so reviewers can focus on risk and strategy rather than line‑by‑line slog.

Built for scalability and collaboration - with on‑prem, private cloud and web deployments that help address data‑residency concerns - Kira surfaces clause frequency, relationships and outliers, speeds diligence workflows (often cutting review time dramatically) and plugs into familiar tasking and reporting steps; see the Kira product overview and the Kira M&A due diligence workflow guide to judge fit.

For VN practice, pair Kira pilots with clear oversight gates and retraining so junior lawyers validate outputs and turn faster reviews into higher‑value client advice.

For Vietnamese legal teams facing cross‑border disputes, internal investigations or growing DSAR workloads, Everlaw offers a cloud‑native, end‑to‑end ediscovery platform that turns huge, messy datasets into courtroom‑ready evidence: the product combines industry‑leading ingestion (900K docs/hour), machine learning‑driven predictive coding and the EverlawAI Assistant for near‑instant document summaries, plus Storybuilder for collaborative timelines and trial prep, so a terabyte of mixed files can be processed and made searchable in hours rather than weeks.

Practical for VN practice: native‑format review, automatic OCR/transcription and foreign‑language translation (109+ languages, including Vietnamese) speed multilingual matters, while security certifications (SOC 2 Type 2, FedRAMP/StateRAMP and ISO 27001) and API integrations with Office 365 help firms keep sensitive client data under control.

Teams piloting Everlaw should pair demos of the product tour and ediscovery features with governance steps from local guidance - retraining junior lawyers into oversight roles is a pragmatic way to validate AI summaries and preserve privilege during rollout.

See Everlaw's product overview and the dedicated ediscovery page for demos, or our retraining guidance for hands‑on rollout tips in Viet Nam.

Feature	From Everlaw
Processing speed	Up to 900K documents per hour
Language & media support	Automatic OCR/transcription and translation in 109+ languages (includes Vietnamese)
Security & compliance	SOC 2 Type 2; FedRAMP Moderate; StateRAMP; ISO 27001

“Everlaw is easily the most intuitive attorney-friendly coding platform I've ever used.”

Closing a toolkit for Vietnamese legal teams means marrying practical AI tools with hard compliance: start from Vietnam's evolving data protection framework (PDPD, upcoming PDPL and related laws) and treat DPIAs, Transfer Impact Assessments and data‑localization rules as operational checkpoints rather than paperwork - DLA Piper's Vietnam data protection overview is a useful reference on required TIAs, 60‑day filings and the MPS authorities to watch.

Pick tenant‑first, auditable tools, enforce human‑in‑the‑loop review and appoint DPOs where processing of sensitive data triggers additional safeguards, and convert faster drafting into higher‑value legal advice by retraining junior lawyers into oversight roles (see our retraining guide).

For teams that need structured upskilling, consider a focused program like the AI Essentials for Work bootcamp (Nucamp - 15 Weeks) to learn promptcraft, DPIA basics and vendor due diligence before a wider rollout.

The practical playbook is simple: map data flows, run DPIAs before pilots, enforce scoped access and review gates, and pair each tool with documented governance so productivity gains do not become regulatory risk.
