Legal professionals are dealing with growing complexity and rising workloads. As a result, many are turning to AI to streamline processes, enhance compliance, and deliver faster, more accurate work. However, not all AI tools are equal. 

This guide runs through the best AI tools for lawyers in 2025, with a focus on who they’re best for, and security. Some have been designed for legal work, while others are general use AI tools.

Why are AI tools important for lawyers in 2025?

Legal AI tools are becoming essential to meet today’s expectations of efficiency and accuracy. Manual processes and traditional methods cannot keep up with growing regulatory demands, tight deadlines, and client requests.

Some AI tools automate tasks like drafting, review, analysis, and risk assessment, reducing errors and freeing legal teams to focus on strategic work. Other tools can be used to streamline billing or communications, making it easier to manage third-party relationships. 

Wherever legal teams implement AI, they will gain the ability to deliver faster, more accurate services, optimise operations, and stay competitive in a rapidly evolving market.

ChatGPT

ChatGPT, developed by OpenAI, is a well known general-purpose AI model capable of drafting, summarising, and explaining legal documents. It could be used for basic legal research, preliminary agreements, and straightforward questions.

However, ChatGPT is not a specialised legal AI. A major limitation is that data inputs are not private or secure, making it unsuitable for handling sensitive client information. Outputs must also be reviewed carefully for accuracy and compliance.

Claude

Claude, developed by Anthropic, focuses on context-awareness, and could be used to help draft legal documents and analyse queries. It handles longer inputs, making it suitable for legal texts. 

However, data inputs are not stored privately, which means it shouldn’t be used for confidential information. Like ChatGPT, its outputs require human oversight to ensure compliance and precision.

Gemini

Gemini, Google DeepMind’s AI, uses advanced NLP and real-time data access for drafting, summarising, and analysing. Integrated with Google Workspace, it’s convenient for teams already using Google's ecosystem. 

Top features to look for in legal AI tools

Choosing the right legal AI tools begins with clearly defining your use cases. Evaluate whether it delivers efficiency and accuracy by testing in a sandbox environment. Integration with your existing legal software helps maintain uninterrupted workflows.

For cross-jurisdictional work, multi-language capabilities are essential, enabling precise drafting, analysis, and collaboration. Advanced natural language processing (NLP) can improve accuracy, reduce errors, and boost productivity.

Generative AI (GenAI) models are advancing rapidly, with vendors constantly improving their capabilities. Some models excel at specific tasks, so choosing model-agnostic tools allows you to make the most of various models for optimal performance.

Legal AI tools tailored for legal teams should limit sources of guidance to legal codes and court case histories relevant to specific jurisdictions. Ensure the tools you choose cover the necessary jurisdictions and constrain sources to provide accurate and reliable advice.

Why security and compliance are non-negotiable for legal AI

Legal work involves vast amounts of sensitive data, making robust safeguards essential. Breaches not only compromise client confidentiality but also expose organisations to legal and reputational risks. 

The best AI tools anonymise client information before processing, ensuring data remains protected at every step.

Compliance with laws such as GDPR, and frameworks like ISO 27001, and SOC2 is also important. These standards ensure data handling aligns with global regulations. Reliable legal AI combines security, compliance, while maintaining strict confidentiality. 

Challenges and ethical considerations in using AI for legal work

AI brings efficiency to legal work, but it also comes with challenges. These include:

1. Bias in algorithms  

AI systems can inherit biases from the data they’re trained on. This is a serious issue for legal work, where fairness is key. LEGALFLY, for example, tackles this by using transparent data processing and ensuring its training data aligns with jurisdiction-specific standards.

2. Transparency  

Legal teams need to know how AI reaches its conclusions. If outputs can’t be explained or verified, it undermines trust. The best tools prioritise transparency, making every output traceable to its source and reasoning. LEGALFLY, for example, delivers in-line resources for every AI output.

3. Accuracy and reliability  

AI outputs can be wrong, especially with incomplete or ambiguous inputs. Human oversight always helps to maintain accountability and credibility in legal decision-making.

Conclusion

AI tools are enabling lawyers to work faster, smarter, and with greater precision. By automating routine tasks, enhancing compliance, and ensuring data security, these tools address the growing complexity of legal work. 

As more firms adopt AI, those equipped with the right tools will deliver better results, meet client expectations, and stay competitive in an evolving market. Choosing the right tool will make all the difference. The best offer reliable security, jurisdiction-specific accuracy, and user-friendly design, tailored specifically for legal teams.
